1.0 INTRODUCTION
During the week of September 1, 1986, Entropy Environmentalists, Inc.
(Entropy), under contract to the U. S. Environmental Protection Agency,
Emission Measurement Branch, conducted an emission measurement program at the
Exxon Refinery in Baytown, Texas operated by the Exxon Company, U. S. A. The
purpose of the measurement program was to provide data on chromium emissions
from cooling towers in support of a possible chromium standard under the
National Emission Standards for Hazardous Air Pollutants (NESHAPS).
Comprehensive testing was conducted at two cooling towers located at the
Baytown Refinery. Cooling tower No. 68 consists of two sections with two
counterflow cells in one section and a crossflow cell in the other section.
Both sections of No. 68 are equipped with typical-efficiency drift
eliminators. Cooling tower No. 84 consists of four counterflow cells, each
equipped with a high-efficiency drift eliminator. These two cooling towers at
the Baytown facility were selected for source testing for the following
reasons:
o The refinery operates both high-efficiency and typical-efficiency drift
eliminators on cooling towers with chromate-based cooling water
treatment programs. The test data should provide a basis for comparing
the performance of these two drift eliminator types.
•	Cooling tower No. 68 has both crossflow and counterflow sections and
provides a comparison of emission characteristics from these two types
of tower design.
•	The facility operates the two cooling towers in a manner considered
representative of other industrial cooling towers.
•	Operating parameters were easily maintained and monitored during the
tests to ensure proper conditions existed.
1-1
-------
• The facility agreed to allow the addition of sodium bromide (NaBr) to
the cooling tower water for further evaluation of bromide as a
surrogate compound for cooling tower drift emissions testing.
The cooling tower emissions were characterized using a Method 13~type im-
pinger train following the draft cooling tower test method (Appendix C) to
collect the drift from the cooling tower exhaust. The impinger contents were
analyzed by Research Triangle Institute (RTI) for total chromium content by
solubilizing the chromium with nitric acid and using graphite furnace atomic
absorption (GFAA). The velocity of the airflow through each fan cell was deter-
mined using a propeller anemometer following the draft method (Appendix C). The
gas temperature and percent moisture were also determined. The corresponding
cooling water samples collected during each sampling run were analyzed by RTI
for hexavalent chromium using the diphenylcarbazide wet chemical method and by
North Carolina State University (NCSU) for total chromium in the filtered
residue using Neutron Activation Analysis (NAA). Sampling was also conducted
using an "aligned nozzle train" and a "disc train" (see Chapter 4) to determine
the percentage of chromium emissions associated with drift particles smaller
than a certain particle size (approximately 15 um).
An independent determination of the drift rate and drift size distribution
was conducted by personnel from Environmental Systems Corporation (ESC) using
their Sensitive Paper (SP) system and microscopic analysis. ESC personnel also
conducted the waterflow measurements on the two cooling towers. For this, ESC
used calibrated pitot tubes and a methodology similar to EPA Methods 1 and 2 for
air velocity measurements.
A sampling protocol using absorbent papers and ion exchange papers in a
sensitive paper holder was evaluated as part of an effort to develop a potential
screening technique for cooling tower emission testing and to determine the
percentage of chromium emissions associated with particles greater than a
1-2
-------
certain particle size (approximately 30 um). These AP's were analyzed for
total chromium content by NCSU using NAA.
Mr. David Randall of Midwest Research Institute (MRI) monitored the
operating conditions of the cooling tower and determined when conditions were
suitable for sampling. Mr. Dan Bivins (EPA Task Manager) of the Emission
Measurement Branch (EMB) was present to observe the testing program. Mr. E. W.
Biggers of Exxon Company served as the contact for the Baytown Refinery
facility.
This report is organized into several sections that address the various
aspects of the testing program. Immediately following this introduction is the
"Process Operation" section describing the process involving the cooling tower
tested, the cooling tower systems, and the control equipment in each tower.
Following the "Process Operation" section is the "Summary of Results" section
presenting tables summarizing the test conditions, the calculated emission and
drift rates, the drift size distribution, and the analytical results. The next
section, "Sampling Locations and Test Methods" describes and illustrates the
various sampling locations for the emissions testing program and then explains
the sampling strategies used. The final section, "Quality Assurance,"
describes the procedures used to ensure the integrity of the sampling and
analysis program. The Appendices present the Test Results and Example
Calculations (Appendix A); Field and Analytical Data (Appendix B); Sampling and
Analytical Procedures (Appendix C); Calibration and Quality Assurance (Appendix
D); MRI Process Data (Appendix E); and Test Participants and Observers
(Appendix F).

2.0 PROCESS OPERATION
2.1	PROCESS DESCRIPTION AND OPERATION
The two towers tested, Nos. 68 and 84, provide cooling for a number of
refining processes. Tower No. 68 serves the catalytic light end units which
recover ethylene and other light end products. The cooling requirements of the
vacuum distillation unit for lube oil provide the main heat load on tower No.
84. Both towers handle a constant heat load 24 hours per day. Figures 2.1 and
2.2	are sketches of tower Nos. 68 and 84, respectively.
2.1.1 Tower 68
Tower Description - This tower consists of four counterflow cells and one
Marley crossflow cell. Each cell has one single-speed fan and redwood
herringbone drift eliminators. The counterflow section has redwood splash fill
and is served by two risers that distribute the water over the fill through a
manifold and pressure spray nozzles. The crossflow section has plastic splash
fill and is served by one riser that supplies a water distribution deck
equipped with gravity flow nozzles. Water flow rates were not known before the
test, but pump curves indicate that peak efficiency would be achieved at a flow
rate of about 19,500 gallons per minute (gal/min). Two pumps circulate water
from the northern end of the common basin to the process heat exchangers, and a
third pump is on standby. Blowdown is withdrawn from the system before the
water is returned to the tower. Makeup water from the San Jacinto River is
supplied through a 4-inch pipeline to the basin. The fans are 18 feet in
diameter in the counterflow cells and 24 feet in diameter in the crossflow
cell, but the airflows were not known before the test.

Chemical treatment and monitoring system - The corrosion inhibitor is Betz 10K,
which is a chromate/zinc formulation. The target concentration of chromate in
the recirculating water is 10 to 15 parts per million (ppm). The solution is
added automatically at a rate that is set manually. Dispersant is added
automatically at a rate that is set manually. Dispersant is added in the same
manner. A free chlorine residual of 0.2 to 0.5 is the target for control of
microbiological growth. Chlorine gas is injected into a side stream of the
makeup water and added to the southern end of the basin. Both the chromate and
free chlorine residual are measured once per shift by the operating personnel
and about twice a week by the Betz representative.
The pH of the water is monitored continuously, but it is not used as an
automatic controller. When pH exceeds the critical control range of 6.0 to
9-0, it must be corrected by manually adding acid or caustic soda. The ratio
of calcium hardness in the recirculating water to that in the makeup water
defines the number of cycles of concentration. This value is only used as a
general indicator of system operation. Blowdown is dictated by the
conductivity, which should not exceed 1,500 micromhos (umhos). Part of the
blowdown is discharged through a rotameter, but the capacity of the rotameter
is insufficient to provide measurement of the full blowdown flow. Thus, a
bypass is used for part of the blowdown discharge. Maximum discharge through
both lines (as during the test) generally keeps the conductivity in the control
range of 900 to 1,200 umhos. If it is necessary to reduce the blowdown
(perhaps because of reduced load, and, therefore, reduced water recirculation),
flow through the rotameter or bypass can be reduced. However, if it is
necessary to increase the blowdown (because of increased conductivity of the
makeup water, for example), a valve in the process area or at the pumps must be
opened to increase the discharge.

Operating Conditions During the Testing - The operating parameters that were
monitored throughout the test period to ensure that appropriate conditions
existed included fan motor amperage, pump outlet pressure, hot water line pres-
sure, water flow in each riser, temperature in each riser, basin water temper-
ature, pH, conductivity, wind speed and direction, and dry bulb temperature.
The makeup flow rate was also monitored September 2, and the blowdown was
estimated that afternoon. Table 2.1 is a summary of the cooling tower
operating parameters and meteorological data recorded during the test period.
On Sunday, August 31. ESC personnel measured the recirculating water flow
rates. The flow in the crossflow cell was about 20 percent greater than the
flow in each of the counterflow cells. The pump head pressure and the
manufacturer's pump curve indicated that the flow should be about 21,500
gal/min, which is 92 percent of the measured flow (23,400 gal/min). Design
flow rates for the tower were not available, but the pumps were being operated
normally within 90 to 100 percent of the design flow and near peak efficiency.
The amperage required by the fans was constant, although different among the
four fans, and the fans were also operating normally. Therefore, no changes
were made to the air or water flow rates for the test.
The drift eliminator on one side of the crossflow cell was determined to be
in good condition on the visual inspection through the doorway at one end of
the tower. The drift eliminators in the counterflow cells could not be
inspected, but the quantity of drift out of each stack appeared similar
although it may have been slightly less from cell No. 1. The quantity of steam
(presumably a combination of drift and condensed water vapor) rising from cell
No. 1 also appeared to be slightly less than that from the other cells. Some
of the nozzles in the distribution deck on cell No. 5 were plugged, and a few
of the redwood slats in the lower sections of the counterflow cells were
broken; however, the overall condition of the tower was reasonably good.

Water meters are not installed on the makeup and total blowdown lines. To
estimate these flows, alternative methods were attempted. On September 3.
1986, a meter was connected to the pressure taps on an existing orifice plate
in the makeup line. This indicated an average flow of about 280 gal/min over
the 6 hours of monitoring (greater in the afternoon than in the morning), but
did not include the 15 to 20 gal/min diverted for chlorine injection or the
amount leaking through a valve into the system from a nearby tower. That tower
(No. 58) is treated with a phosphate inhibitor from Calgon. The Betz
representative used the phosphate concentration in the recirculating water of
tower No. 68 to calculate a gain of about 25 gal/min. The Calgon
representative estimated the loss from tower No. 58 to be about 100 to 150
gal/min. The Betz calculation is probably more accurate, since Calgon only
made a rough estimate of the difference in blowdown from tower No. 58 on
Friday, September 5. from the blowdown earlier in the year without the benefit
of a meter on the blowdown line. (Later work by Exxon confirmed that the Betz
estimate was correct.)
To estimate the tower No. 68 blowdown, the combined flow through the
rotameter and bypass was diverted to a 55~gallon drum. The time to fill the
drum a couple of times was recorded. This produced a flow rate within 20
percent of the estimate calculated by the Betz representative based on cycles
of concentration and an estimate of evaporation.
Water temperatures also are not monitored by online equipment. Therefore,
fittings were attached to taps on the three risers and the hot water return
line itself. Mercury-in-glass thermometers were used to record the
temperature. The basin temperature was determined about 5 feet from the basin
wall below cell Nos. 1, 2, and 5- A mercury-in-glass thermometer was placed in
a perforated can that was attached to a length of conduit. With this method,
it was not possible to determine the actual temperature drop in each cell, but
the average basin temperature in all three locations was the same.
2-8
-------
Two sources of meteorological data were available: one station set up at
the tower and one maintained by Exxon refinery personnel less than a mile from
the tower. Both stations indicated that the wind direction was from the
southeast, and very few directional changes deviated more than 45 degrees from
the southeast. Both average and peak wind speeds, however, were considerably
higher at the tower station. Other than instrument calibration differences,
the reason for this is not clear. There may have been a slight tunneling
effect created at the tower station where the wind had to pass between the
cooling tower and a cryogenic process column (and other shorter equipment) 30
to 40 yards downwind of the station. Gusts rarely exceeded 15 mph, and drift
was never visible from the side of the crossflow tower. The ambient
temperature also varied between the stations. The actual temperature is
probably that obtained at the tower site since the several thermometers that
were used recorded the same levels.
On Friday, August 29, 1986, the Exxon process personnel responsible for the
tower disconnected the chlorine injection line to preclude any possible adverse
health effects on test personnel. Chlorine will also react with most
hydrocarbons. Thus, a decrease in the free chlorine residual concentration
(normally determined once per shift) is the best indicator of a process fluid
leak into the water. Alternatively, gas traps on the hot water return line,
visual inspection of the surface of the water in the basin and the distribution
deck of cell No. 5. and the chromate concentration were used to confirm that
the process heat exchangers were not leaking. The chromate concentration, as
determined by the operators each shift, was essentially constant and within the
desired control range during the testing period. The Betz analysis on Tuesday,
September 2, agreed with that of the operators. The pH and conductivity were
also within control ranges.

-------
2.1.2 Tower 84
Tower Description - The tower is a 4-cell (riser and fan) Marley counterflow
design with one 22-ft diameter constant-speed fan per cell. The average
airflow per fan as measured by Entropy was about 550.000 dry standard cubic
feet per minute (dscfm). Each cell is equipped with PVC film fill and a
high-efficiency Marley XCEL-15 drift eliminator. Water is distributed over the
fill through a manifold and spray nozzles. Two pumps circulate the water from
the basin extension at the south end of the tower through the process heat
exchangers. A recent potassium retention time study determined that the system
volume was about 550,000 gallons of water.
Blowdown is designed to be controlled by the conductivity of the
recirculating water. At certain set points, a valve is actuated in a line off
the main hot water return. Most of the makeup water is supplied through a
6-inch pipe to the basin extension, but part of it is diverted continuously
into five smaller lines. The inhibitor, dispersant, chlorine, sulfuric acid,
and caustic soda are injected into the smaller lines automatically.
Chemical Treatment and Monitoring System - The corrosion inhibitor, Nalco 737^,
is a chromate/zinc formulation in a 7:1 ratio. The target concentration in the
recirculating water is 8 to 12 ppm. The solution is injected into one of the
small makeup lines for a specific fraction of every 10-minute interval. The
on/off time fraction can be changed by entering new values into the computer
memory. The dispersant is injected into another makeup line in an identical
manner. Acid and caustic are injected based on pH set points within the
control range of 6.8 to 7-5- Chlorine gas is injected continuously at a rate
controlled by a free chlorine residual monitor that is generally set to keep
the concentration in the range of 0.3 to 0.5* For this system, the ratio of
the conductivity of the recirculating water to that of the makeup water
2-10
-------
defines the number of cycles of concentration. The conductivity of the makeup
water is about 150 umhos, and the control range for the number of cycles is 6
to 8.
Operating conditions during the testing - The tower is operating at less than
design capacity, but in July 1986 full-time operation began. The following
operating parameters were monitored throughout the test period to ensure that
appropriate conditions existed: (1) fan motor amperage, (2) pump outlet
pressures, (3) cold water line pressure, (4) water flow in each riser, (5)
temperature in three of the risers, (6) basin temperature, (7) temperature in
pump inlet lines, (8) pH, (9) conductivity, (10) wind speed and direction, and
(11) dry bulb temperature. The computerized system that monitors inlet and
outlet temperatures and the makeup, blowdown, and recirculating water flow
rates was not calibrated correctly at the start of the test. With the
exception of the blowdown, attempts at calibration were not successful. These
problems are not considered to affect the amount of drift, and only the makeup
and blowdown could not be monitored directly by the test personnel. Table 2.2
is a summary of the cooling tower operating parameters and meteorological data
recorded during the test period.
On Wednesday, September 3. 1986, ESC personnel measured the water flow
rates in each riser and found the flow in Risers A and B to be about 15 percent
less than the flow in Risers C and D. The total flow was 25 percent greater
than the tower design, and 20 percent greater than the pump ratings. From the
pump head pressure and the manufacturer's pump curves, it was calculated that
the flow should be about 20,600 gal/min. The measured rate was about 10
percent greater than this calculated rate. As scale and fouling increase, and
with additional process heat loads, the head pressure will increase slightly
and cause a decrease in the flow rate. The conditions as measured (and with

all the fans running) represented normal operation. Therefore, no attempt was
made to even the flow in the risers or to reduce the overall flow to the
designed rate.
The drift eliminators could be inspected through a porthole in the fan
stack below the fan. The drift eliminator in Cell A is assumed to have at
least one defect because entrained droplets were observed periodically in the
same area of the stack. The other drift eliminators appeared to be in good
condition. The water distribution through the fill was even, although it did
cascade along some vertical beams at a greater rate than along others.
The quantity of blowdown was not easily determined because the conductivity
control was not working and the valves in the line were closed. Also,
recirculating water can be withdrawn from the system in the process area for
general ground cleaning purposes. The operators, however, indicated that they
had not been using any of this water on the test days. Finally, a water
balance on the process side of the overhead vacuum condensers indicated an
excess of about 50 gal/min. This is just about the amount that the Nalco
representatives calculated for the blowdown based on the cycles of
concentration and an estimation of the evaporation loss. An analysis of the
process fluid for chromate was negative. The makeup could not be monitored
because of the inaccurate calibration.
The recirculating water temperature was measured with mercury-in-glass
thermometers in fittings attached to taps in three of the risers. The basin
temperature was determined with a mercury-in-glass thermometer at the
intersection of the main basin and the basin extension. The temperatures
indicated by gauges on the lines to the pumps were also recorded; they were
always 2 degrees lower than the thermometer reading.

As with tower No. 68, meteorological data were available both at the tower
site and from the Exxon meteorological station almost a mile away. The wind
direction continued to be steady from the southeast, and the wind speeds were
higher on the chart recorder at the tower station. At this site, there were no
obstructions around the station except for the tower itself.
The operator log of the chromate concentration in the recirculating water
was constant at the upper limit of the control range over a 2-day test period.
The concentration agreed with that obtained by the Nalco representative on
August 29. The pH, conductivity, and free chlorine residual were also within
the control ranges.
Possible Effects on Drift Measurements - Several conditions discussed above
could have an effect on the drift measurements; each is considered below.
1.	The recirculating water flow through tower No. 84 is higher than
design, which may result in a higher rate of drift than would be
produced if the tower were operating at the designed rate (and at a
higher temperature range). Comparison of drift measurement from Cell B
(5,200 gal/min) with measurements from Cells C and D (6,100 gal/min)
should confirm this. However, the current operating conditions are not
an operating problem, and there is no incentive to modify them.
2.	The rate of drift from Cell A in tower No. 84 is likely to be higher
than that from Cell B because of the apparent defect in the drift
eliminator of Cell A.

3.0 SUMMARY OF RESULTS
Tests were conducted to determine the mass emission rates of hexavalent
chromium and total chromium from cooling tower Nos. 68 and 84 at Exxon
Company's Baytown Refinery in Baytown, Texas. Four of the cells on tower
No. 68 (fan cells No. 1-4) were counterflow cells and were served by two
risers. Fan cell No. 5 was a crossflow type and had its own riser. Because of
its configuration, tower No. 68 was treated as two separate towers for testing
purposes and represented: 1) a counterflow tower with standard-efficiency
drift eliminators and 2) a crossflow tower with a standard-efficiency drift
eliminator. Tower 84 was a counterflow tower with a high-efficiency drift
eliminators. The mass emission rate tests used a Method 13~type impinger train
to sample the five fan stacks on three riser cells on tower No. 68 and the four
fan stacks on four riser cells on No. 84. The testing schedules that were
followed for the Exxon cooling towers are presented in Tables 3-1A and 3-IB.
The results of these tests are discussed briefly below and in detail in
Section 3-1-
The pollutant mass emission rates for hexavalent chromium, calculated by
the ratio of areas (PMRa) method, for the counterflow cells on tower No. 68
ranged from 275 to 25,000 milligrams per hour (mg/hr), for the crossflow cell
on tower No. 68 ranged from 2,500 to 58,500 mg/hr, and for the four riser cells
on tower No. 84 ranged from 210 to 9.900 mg/hr. As is evident, the pollutant
mass emission rates measured for hexavalent chromium were highly variable from
run to run even for runs conducted on the same cell. Measured emission values
for the same cell showed, in most cases, a 10- to 50-fold difference. However,

when simultaneous runs which were conducted on different cells were compared,
the mass emission rate values typically showed only a 1- to 5~fold difference.
This indicates that cooling tower chromium emissions may vary widely with time
and/or ambient conditions.
The drift size distribution (drift being defined here as cooling water
entrained in the exit air and emitted to the atmosphere in droplet form), along
with the drift rate, was determined by Environmental Systems Corporation (ESC)
using their sensitive paper (SP) technique. The results of the SP testing
suggest that the drift emissions from the counterflow fan cells on tower No. 68
had an average mass mean diameter of 290 um; from the crossflow cell on tower
No. 68, an average mass mean diameter of 360 um, and from the counterflow cells
on tower No. 84, an average mass mean diameter of 235 um.
Another particle sizing method was evaluated for determining the percent of
hexavalent chromium in particles smaller than a certain size (approximately
15 um under these sampling conditions). The sampling protocol involved using a
set of paired trains; one, referred to as the "disc train," was designed to
capture only the smaller particles (less than 15 um) and the other, a Method
13~type train with the nozzle aligned directly into the flow of the fan exhaust
(referred to as the "aligned nozzle train"), was designed to capture all sizes
of drift particles. Data from two screening techniques being evaluated
utilizing absorbent paper (AP) and ion exchange paper (XP) were also used for
particle sizing purposes. The AP and XP data were used based on collection
(under these sampling conditions) of particles greater than approximately 30 um
in diameter.
The paired train particle sizing data suggest that most of the hexavalent
chromium emissions from the fan cells tested on the two towers are associated
with particles less than 15 um. The data from the paper collection techniques
for these cells suggest that 1.0 to 15-1 percent of the chromium emissions from
3-3
-------
the standard-efficiency drift eliminators and 1.0 to 2.9 percent from the high-
efficiency drift eliminators are associated with particles greater than 30 um.
The particle sizing results and the differences between the two methods are
discussed in detail in Section 3.2.
The analytical results for hexavalent chromium and residue (trivalent)
chromium in the cooling water samples and the total chromium in the impinger
samples are presented in Section 3-3 along with the analytical results for the
blanks and the quality assurance samples. The results of the analysis of the
absorbent papers and ion exchange papers, which are being evaluated as screen-
ing techniques for cooling tower emissions, are also presented in Section 3-3.
and the techniques are discussed in Section 3-4-
Drift rate calculations based on the water flow to the riser cells, the
concentration of chromium in the cooling water, and the mass emission rates
calculated from the impinger train samples and the AP and ion exchange paper
samples are presented in Section 3-5- Drift rate calculations from the SP data
are also presented and the drift rates calclulated by the various methods are
compared.
3.1 HEXAVALENT CHROMIUM AND TOTAL CHROMIUM EMISSIONS
The mass emission rates for hexavalent chromium and total chromium for the
nine fan cells on the two towers were determined. Sampling was conducted
isokinetically with the isokinetic values for the fifteen sampling runs ranging
from 99-7% to 109-5% (see Table 3-2). The sampling runs were typically 2 hours
in length, with a single traverse on each fan stack cell comprising a single
sample; for fan cell 5 on tower 68, which was treated as a separate tower, two
perpendicular traverses were conducted. Stack gas conditions were calculated
assuming that the exhaust was saturated.

The hexavalent chromium emissions in the drift were calculated using the
values for the total chromium emissions and the ratio of hexavalent-to-total
chromium in the cooling water. The assumption was made that the chromium
emissions from the cooling tower fan stack maintained the same ratio of
hexavalent-to-total chromium measured in the cooling water.
The concentration of hexavalent and total chromium emissions, in milligrams
per dry standard cubic meter (mg/dscm), micrograms of chromium per gallon of
cooling water flow through the tower for that fan cell (ug/gal), and milligrams
per million Btu's of heat removed (mg/10^ Btu), and the mass emission rates of
hexavalent and total chromium, in milligrams per hour (mg/hr) are presented in
Table 3-3 for each sampling run. These results are based on the total chromium
analysis conducted by RTI using GFAA with the hexavalent chromium values
calculated using the ratio of hexavalent-to-total chromium in the cooling water
sample for that run. The hexavalent and total chromium values are
representative of the emissions from a single fan stack on the corresponding
riser cell. The mass emission rates were calculated using the ratio of the fan
stack area to the sampling nozzle area, the catch weight of total chromium or
the calculated catch weight of hexavalent chromium, and the sampling time (see
Appendix A for example calculations).
3-1.1 Tower 68, Counterflow Fan Cells, Standard-Efficiency Drift Eliminators
Flue Gas Conditions - A summary of the flue gas conditions for the counterflow
fan cells tested on tower No. 68 is presented at the top of Table 3-2. The
volumetric flow rates were fairly constant for all four fan cells and averaged
550,000 actual cubic meters per hour (19,300,000 actual cubic feet per hour).
The stack temperature for these fan cells averaged 31°C (88°F) and the moisture
content averaged 4.5/°- The isokinetic sampling rates were well within the
allowable limits for all four runs.

Hexavalent Chromium Emissions - A summary of the hexavalent chromium emission
values for the test runs conducted on the four counterflow fan cells on tower
No. 68 is presented in Table 3* 3- The hexavalent chromium concentrations for
the four fan cells were quite variable and ranged from 0.0005 to 0.044 milli-
grams per dry standard cubic meter of exhaust gas, 1.1 to 100 micrograms per
gallon of water flow to the fan cells, and 2.8 to 258 milligrams per million
Btu's of heat removed from the water. The mass emission rates of hexavalent
chromium for the four cells ranged from 275 to 25,100 milligrams per hour.
Total Chromium Emissions - The total chromium emissions for each test run on
the counterflow fan cells on tower No. 68 (see Table 3-3) were also variable,
but were consistent with the corresponding hexavalent chromium emissions. The
total chromium emission concentrations ranged from 0.0005 to 0.044 milligrams
per dry standard cubic meter, 1.1 to 100 micrograms per gallon of water flow,
and 2.8 to 259 milligrams per million Btu's removed. The mass emission rates
for total chromium ranged from 275 to 25,100 milligrams per hour.

Flue Gas Conditions - The flue gas conditions for fan cell #5 (crossflow) on
tower No. 68 are presented in Table 3-2. The volumetric flowrates for all
three runs conducted on this cell were consistent and averaged 1,630,000 actual
cubic meters per hour (57.400,000 actual cubic feet per hour). The stack
temperature averaged 31°C (88°F) and the moisture content averaged 4.3#. The
isokinetic sampling rates were well within the allowable range for all three
runs.

Hexavalent Chromium Emissions - The summary of hexavalent chromium emission
values for the crossflow fan cell on tower No. 68 is presented in Table 3-3•
As for the counterflow cells, the hexavalent chromium concentrations for the
three runs on the crossflow section of tower No. 68 were variable. They ranged
from 0.0016 to 0.039 milligrams per dry standard cubic meter, 5-9 to 136
micrograms per gallon of water flow, and 10.1 to 262 milligrams per million
Btu's of heat removed. The mass emission rates of hexavalent chromium ranged
from 2550 to 58,600 milligrams per hour.
Total Chromium Emissions - The total chromium emissions for the crossflow fan
cell are also presented in Table 3-3. The total chromium emission concentra-
tions for the runs on this fan cell ranged from 0.0016 to 0.039 milligrams per
dry standard cubic meter, 5-9 to 136 micrograms per gallon of water flow to the
fan cell, and 10.1 to 262 milligrams per million Btu's of heat removed. The
mass emission rates of total chromium ranged from 2550 to 58,600 milligrams per
hour.
3.1.3 Tower 68, Simultaneous Runs - When examined as whole and cell by cell,
the hexavalent chromium emissions for tower No. 68 are extremely variable from
run-to-run. However, comparison of the emission values for those runs
conducted simultaneously (1-1 and 5~1. 2-1 and 5~2, and 3~1 and 5~3) reveals a
distinct correlation. For example, there is a 91-fold difference between the
two mass emission rates calculated for riser cell E (Runs 1-1 and 4-1) and only
a 2.3~fold difference between the mass emission rates for the two runs
conducted simultaneously (1-1 and 5~1) on riser cells E and G. Similar
comparisons show 8- and 23-fold differences in the mass emission rates for the
runs for riser cells F and G, respectively, and only 1.8- and 4.8-fold
3-9
-------
differences for the two pairs of simultaneous runs (2-1 and 5~2, and 3~1 and
5-3. respectively) conducted on these two riser cells.
3.1.4 Tower 84, Counterflow Fan Cells, High-Efficiency Drift Eliminators
Flue Gas Conditions - The flue gas conditions for the four pairs of runs
conducted on the four counterflow fan cells with high-efficiency drift
eliminators on tower No. 84 are presented in Table 3-2. The volumetric
flowrates for all runs on all four cells were fairly consistent and averaged
1,010,000 actual cubic meters per hour (35.800,000 actual cubic feet per
hour). For these four cells, the stack temperature averaged 33°C (91°F) and
the moisture content averaged 4.9$. The isokinetic sampling rates for all
eight runs were well within the acceptable range.
Hexavalent Chromium Emissions - A summary of the hexavalent chromium emissions
for the test runs conducted on tower No. 84 is presented in Table 3-3- The
hexavalent chromium emission concentrations for the four cells on the tower
were again variable and ranged from 0.0002 to 0.012 milligrams per dry standard
cubic meter, 0.7 to 27 micrograms per gallon of water flow, and 1.2 to 68 mill-
igrams per million Btu's of heat removed. The mass emission rates of
hexavalent chromium for the four cells ranged from 230 to 9,900 milligrams per
hour.
Total Chromium Emissions - The total chromium emissions for the fan cells on
tower No. 84 are also presented in Table 3«3 and were consistent with the
corresponding hexavalent chromium emissions. The total chromium emission
concentrations emitted by the four cells ranged from 0.0002 to 0.012 milligrams
per dry standard cubic meter, 0.7 to 27 micrograms per gallon of water flow,
and 1.2 to 68 milligrams per million Btu's of heat removed. The mass emission
3-10
-------
rates of total chromium from the fan cells on this tower ranged from 230 to
9,900 milligrams per hour.
3.I.5 Tower 84, Simultaneous Runs - Like tower 68, when examined as a whole
and cell by cell, the hexavalent chromium emissions for tower 84 are extremely
variable. Comparison of simultaneous runs (A-l and C-l, A-2 and C-2, B-l and
D-l, and B-2 and D-2), however, yields much less variability. Comparison of
the hexavalent chromium emission values for the pairs of runs conducted on
riser cells A and C show a 10- and a 23-fold difference, respectively.
However, comparison of the values for the simultaneous runs conducted on the
same two fan cells show only 2- and 1.2-fold differences. In a similar manner,
comparison of the values for the pairs of runs conducted on cells B and D yield
3~ and 47-fold differences, while comparison of values for the simultaneous
runs on the same two cells show differences of 3-3~ and 43-fold.
3.2 SIZE DISTRIBUTION OF DRIFT AND CHROMIUM
3-2.1 Size Distribution of Drift
The drift size distribution and the drift rates were measured by ESC, using
their sensitive paper (SP) technique, for each fan cell tested by Entropy. The
total flux, the mean particle diameter for mass and particle count, the mass
emission rate, and a drift rate expressed as a percent of water flow to the fan
cell are presented in Table 3-4 for each of the nine fan stacks tested. The
drift rates calculated using the SP data as a percent of water flow averaged
0.007# for the counterflow cells on tower No. 68, 0.005# for the crossflow cell
on tower No. 68, and 0.0007# for the counterflow cells on tower No. 84.
The mass mean diameter of the drift is that particle diameter at which half
the drift mass is composed of particles with diameters larger than the mean di-
ameter and half the mass is composed of particles with diameters smaller than

3.2.2 Size Distribution of Chromium
Two methods were used for estimating the percent of hexavalent chromium in
two particle size ranges. The first method involved the use of paired trains
with an "aligned nozzle train" and a "disc train" (described in Section 4.11).
The aligned nozzle train, which was used for a reference measurement, was
designed to collect; all particle sizes isokinetically. The disc train was
operated at the same sampling rate as the nozzle train and was designed to
collect primarily the smaller particles (less than about 15 um). Tne purpose
of the paired train particle sizing was to determine the percent"of the
chromium emissions associated with the smaller particles.
The second particle sizing method, the absorbent paper (AP) technique, was
also being evaluated as a screening method for cooling tower testing. Southern
Research Institute's (SoRI) Aerosal Science Division calculated the cut sizes
for both particle sizing methods. Using the fan cell gas velocity and the
inside diameter of the disc train probe, SoRI calculated the diameter of
particles collected at 50 percent efficiency (D„) bv the disc train. The D„
DU	?0
for the disc train runs ranged from 12.6 to 12.7 um (see Appendices A and C)
with particles less than this size range being collected. The D,_0 for the AP
5U
sampling device, which collected primarily larger particles (i.e., 30 um and
up), ranged from 27.0 to 32-5 um with particles larger than this size range
being collected.
The ratio of the emission rates of hexavalent chromium measured by the
paired trains for runs 1, 2, 3, 4, and 5 for fan cells on risers E, F, G, D,
3-13
-------
and A, respectively, are shown in Table 3>5« In one instance, comparing the
disc train value with the impinger train value indicates that the disc train
collected over 10C$ of the hexavalent chromium as compared to the nozzle
train. In two more instances, the disc train collected over 50% of the
hexavalent chromium as compared to the nozzle train. These instances suggest
that a significant portion of the chromium emissions from the fan cells are
associated with particles less than 15 um.
The second particle sizing method involved using the AP device attached to
the traversing impinger train. The percent of chromium associated with parti-
cles greater than the 30 um cut size was calculated using the ratio of the PMR
3.
values for the AP device and the corresponding impinger (IMP) train run values
(see Table 3-5)- The ratio of the AP to impinger train values ranged from 1.0%
to 15-1# for the fan cells tested. This suggests that only a small portion of
the chromium emissions are associated with particles larger than 30 um.
3.3 SUMMARY OF ANALYTICAL RESULTS FOR HEXAVALENT CHROMIUM AND TOTAL CHROMIUM
3.3-1 Cooling Water Samples
Two analytical techniques (see Figure 4.3) were used for the analysis of
hexavalent chromium and total chromium in the cooling water samples. To
measure hexavalent chromium, a portion of each cooling water sample was
analyzed by RTI using the diphenylcarbazide colorimetric procedure. Another
10-ml aliquot of each cooling water sample was filtered through a Teflon filter
with a 1.0-um pore size. The filter, which was used to catch the insoluble
trivalent (Cr+^) chromium residue, was then analyzed for total chromium by NCSU
using NAA. The sum of the hexavalent chromium (Cr+^) and the residue on the
filter (Cr+^) then represents the total chromium content of the cooling water.
Cooling water blanks were taken from each cooling tower before the addition of
the sodium bromide.

The hexavalent chromium results for the diphenylcarbazide analysis of the
cooling water samples presented in Table 3*6 show a range of 7•33 to 8.71
micrograms per milliliter (ug/ml) of hexavalent chromium. The levels of
trivalent chromium determined using NAA (see Table 3-6) ranged from 0.00 to
0.309 ug/ml.
The ratio of hexavalent chromium to total chromium in the cooling water
based on the NAA of the cooling water filtrate and filter residue ranged from
0.933 to 1.00 (93•3% to 100.0* hexavalent chromium). The percent hexavalent
chromium value determined for each water sample collected was used to calculate
the hexavalent chromium emissions from the total chromium emissions measured by
the impinger train for that corresponding run.
Cooling water samples collected at the beginning and end of testing on each
cooling tower were also analyzed for calcium (Ca), magnesium (Mg), manganese
(Mn), and sodium (Na) content, and pH. The results for these analyses Eire
presented in Table 3-7-

train and paired train samples, consisting of the impinger contents and rinses,
the probe rinses, and a filter, were analyzed principally by RTI using graphite
furnace atomic absorption (GFAA). Each result was blank corrected using the
results of a DI water or a DI water/filter blank. The chromium in each sample

was first solubilized using nitric acid so that the GFAA analysis, which meas-
ures only soluble chromium, would yield results for total chromium. A small
correction factor was added to the sample results to account for a prior NAA
analysis of a small aliquot of each sample (see example calculations in
Appendix A).
Prior to analysis, each sample was concentrated down in a glass beaker and
then transferred to another container. Each beaker used was then treated with
aqua regia to solubilize any residual chromium remaining after sample
transfer. This aqua regia solution (beaker residue) was also analyzed by
GFAA. Thus, the analytical results presented for total chromium in each
impinger sample is the sum of the total chromium for the sample measured by
GFAA (with the NAA correction factor) and the residual chromium recovered from
the sample concentration beakers measured by GFAA (see example calculations in
Appendix A).
The sampling train collection efficiencies (for runs 68-2-1, 68-5-2,
84-A-l, and 84-C-l) are presented in Table 3-9- The collection efficiency for
all runs showed greater than 932 of the chromium being collected in the first
and second impingers.

3-3-3 Absorbent Papers and Ion Exchange Papers
The analytical results for the absorbent paper and ion exchange paper
measurements are also presented in Table 3-8. For these samples, the entire
3-21
-------
47 mm papers were submitted directly to NCSU for NAA. The results in Table 3-8
are also blank corrected using the analytical results for blank papers
(Blank-AP and Blank-XP).
3.3-4 Blanks and Quality Assurance Samples
The results of the analyses for the blanks and the quality assurance sam-
ples are also presented in Table 3-8. There were two blanks for the impinger
train samples. The first type of blank was measured and used to correct the
values for impinger train samples containing a Teflon filter. This blank
consisted of a blank Teflon filter identical to the ones used in the sampling
trains and 500 ml of DI water concentrated to approximately 25 milliliters.
The second type of blank was measured and used to correct the values for the
impinger train efficiency samples consisting of liquid only. The second blank
consisted of 500 ml of DI water concentrated to approximately 25 milliliters.
Blanks for the cooling water analysis consisted of a DI water blank
filtered through a 1.0-um pore size Teflon filter with the filtrate being
collected for analysis. The filter and a 1.0-ml aliquot of the DI water
filtrate were submitted separately for analysis. Ion exchange and absorbent
paper blanks were also measured by NAA to correct for the screening method
sampling (see Section 3-4). The results of the analyses of the quality
assurance samples (audit samples described above) are presented in Table 3-8
and discussed in Section 5*0.
3.4 ABSORBENT PAPER AND ION EXCHANGE PAPER SAMPLING
Sampling protocols using absorbent (filter) paper (AP) and ion exchange
paper (XP) were evaluated in an effort to develop a screening method for
cooling tower emission testing. The absorbent papers and ion exchange papers
were loaded in a device similar to the sensitive paper holder, and were exposed
3-22
-------
to the fan stack exhaust by being attached to the traversing impinger train.
The traversing papers allowed the use of the impinger train results as a
reference to determine the sample collection efficiency of both types of
paper. Other AP's and XP's were loaded in a sensitive paper holder and exposed
to the stack exhaust at a single point. The catch of total chromium on the
papers was determined by placing them directly into 2-ml vials and submitting
the vials for NAA.
PMR 's for total chromium for the paper tests were calculated using the
a
exposed area of the paper (diameter of 4l mm). Some of these results are
presented in Table 3*10 for comparison with the PMF^'s calculated for the
impinger train samples. (The hexavalent-to-total chromium ratios determined
for the cooling water samples can be used to calculate a hexavalent chromium
PMR for the AP's and XP's.) The PMR values for the AP's and XP's were lower
a	a
than the corresponding PMR 's for the impinger trains. This low bias may be
explained by the 30 um cut size calculated for the paper sampling techniques,
with only particles greater than 30 um being collected, and the association of
the majority of the chromium emissions with particles less than 15 um (see
Section 3*2.2).
A separate report will be prepared summarizing the results of the screening
tests conducted at all the cooling towers tested. The evaluation of the use of
sodium bromide as a surrogate for cooling tower emission tests will also be
summarized in the screening test summary report.
3.5 DRIFT RATE DETERMINATION
Drift rates for each sampling run were calculated as a percent of water
flow to the individual fan cells being tested (see Appendix A). The water flow
measurements made by ESC are presented in Table 3-^- The water flow values
used to calculate the drift rates were determined by dividing the total water

flow to the riser by the number of individual fan cells (one or two), because
the PMR values used to calculate the drift rates were for individual fan
a
cells. The drift rates from the impinger train results and the AP and XP
results were calculated using the PMR for total chromium and the total
a
chromium in the cooling water at the time of the sampling run. It was assumed
that the concentration of chromium in the drift was the same as the
concentration of chromium in the cooling water. The drift rates for the
impinger train samples and the AP samples were calculated using the following
formula:
* Drift Rate = 	Cr PMRa (ig/hr) , 1 hour/60 minutes	 x ^
Cr in water (mg/1) x water flow (gpm) x 3-785 L/gal
The calculated drift rates for each run are presented in Table 3-H-
Drift rate as a percent of water flow was also calculated using the mass
emission rate of drift (not chromium) determined by the ESC SP method. The ESC
method is used here for comparison purposes only, as it is not being considered
for use as an EPA reference method. The drift was assumed to have a specific
gravity of 1 gram per milliliter (g/ml). The drift rate was calculated from
the ESC data using the following formula:
mass emission rate (g/sec) x 60 sec/min	„
# Drift Rate = 	—					 x 100#
1 g/ml x water flow (gpm) x 3785-3 ml/gal
The calculated drift rates from the SP results are also presented in Table 3-H
as the average fan cell drift rates for each riser cell tested.
The average drift rates calculated using the impinger train mass emission
rates for riser cells E and F, G, A, B, C, and D were 0.1063#, 0.1874#,
0.0248#, 0.0045#, 0.0390#, and 0.421#, respectively. They averaged 0.1469# and
0.0276# for the riser cells on cooling towers 68 and 84, respectively.

The drift rates calculated using the AP and XP data and the SP results show
a low bias compared to the impinger results and good agreement between the two
methods themselves. The differences between the AP (and XP) and SP results and
the impinger results may be explained based on the observations made by SoRI.
Both the SP and other paper techniques may significantly underestimate the
small droplet flux downstream of high-efficiency drift eliminators. The
possibility also exists that the assumption made for calculating drift on
chromium emissions is incorrect and the concentration of chromium in the drift
throughout the particle size range is not the same as the concentration of
chromium in the cooling water.

4.0 SAMPLING LOCATIONS AND TEST METHODS
This section describes the sampling locations and test methods used to
characterize emissions from the two cooling towers tested at the Exxon Refinery
in Baytown, Texas. The schematics of cooling tower Nos. 68 and 84 and relative
sampling locations are shown in Figures 4.1 and 4.2, respectively. The fan
stacks shown in Figures 4.1 and 4.2 have been systematically assigned numbers
or letters for identification purposes only. Emissions from the fan cell
stacks of both cooling tower Nos. 68 and 84 were sampled to measure chromium
emission and drift rates, drift size distribution, and exhaust gas velocity.
In addition, the water flow rate to each riser cell in both cooling towers was
measured and water samples were taken for analysis for hexavalent and total
chromium. Meteorological conditions were monitored and data collected using a
portable weather station set up adjacent to each cooling tower. The sampling
plan for both cooling towers is presented in Table 4.1. The subsections that
follow further describe each sampling location and the applicable test methods.

Emissions testing for chromium and drift emissions, and drift size
distribution determinations by several methods were conducted over the four fan
cell stacks (Nos. 1 through 4, see Figure 4.1) on the counterflow section of
cooling tower No. 68. As shown in Figure 4.1, each counterflow riser cell for
this section of cooling tower No. 68 has two fan cells; fan cells 1 and 4

are associated with riser cell E and fan cells 2 and 3 are associated with
riser cell F.
Each fan cell stack was approximately 18 feet in diameter at the plane of
the fan blade. Sampling probes connected to sampling train boxes containing
impingers and filter were introduced into the fan cell exhaust and were
suspended from a monorail to facilitate traversing the stack. Three fan cell
stacks (numbered 1, 2, and 3) were 3 feet in height and were 219 inches in
diameter at the plane of the nozzle and train. The fan cell No. 4 was 15 feet
in height and 244 inches in diameter at the plane of the nozzle and train. The
propeller anemometer used to measure the axial component of the exhaust flow
was located 3 to 5 inches above the sampling point.
A Method 13~type impinger train was used for chromium and drift emissions
sample collection. The fan cell stacks were traversed along one axis at 12
points following the draft method (Appendix C). Each of the 12 points was
sampled for 10 minutes for a total of 120 minutes of sampling per run. One run
was conducted at each fan cell stack. The sampling run conducted at fan cell
stack No. 2 had the impinger contents and filter recovered separately for a
collection efficiency check.
Paired train test runs using the "disc" and "aligned nozzle" particle
sizing trains (see Section 4.11) were also conducted. The first run was
conducted for 120 minutes at a single point over riser cell E in addition to
120 minutes of sampling at a single point over riser cell F. The second paired
test train was conducted for 240 minutes at a single point over riser cell F
only.
Sensitive paper (SP) (see Section 4.12) size distribution testing was
conducted once at each sampling location. Sensitive papers of 47 mm diameter
were exposed at each test point. Exposure times were selected in order to
produce samples with a sufficient number of stains to allow confidence in the
4-5
-------
resultant droplet size distribution, and also to prevent overlapping stains.
Local updraft air velocity values were taken at each sampling point using a
Gill propeller anemometer and a Fluke digital multimeter.
Absorbent paper (AP) and ion exchange paper (XP) (see Section 4.13) samples
were collected during each run at various sampling points.
4.2 COOLING TOWER NO. 68 OUTLETS, CROSSFLOW RISER CELL G, STANDARD
EFFICIENCY DRIFT ELIMINATOR (SAMPLING LOCATION B)
Emissions testing for chromium and drift emissions and drift size
distribution determinations by several methods were conducted directly over the
fan cell stack (No. 5. see Figure 4.1) on the crossflow section of cooling
tower No. 68.
The fan cell stack was approximately 24 feet in diameter at the plane of
the fan blade with a height of 18 feet. Sampling probes connected to sampling
train boxes containing impingers and filter were introduced into the fan
exhaust and were suspended from a monorail to facilitate traversing the stack.
The cell stack was 330 inches in diameter at the plane of the nozzle and
train. The propeller anemometer used to measure the axial component of the
exhaust flow was located 3 to 5 inches above the sampling point.
A Method 13~type impinger train was used for chromium and drift emissions
sample collection. The fan cell stack was traversed along two perpendicular
axes with a single traverse and twelve sampling points on each axis following
the draft method (Appendix C). Each of the 12 points on each traverse axis was
sampled for five minutes for a total of 120 minutes of sampling per run. Three
sampling runs were conducted with the impinger contents and filter from one run
recovered separately for a collection efficiency check.
One paired train run was conducted using the "disc" and "aligned nozzle"
particle sizing trains (see Section 4.11) at a single point in the fan cell
stack for a total of 240 minutes.
4-6
-------
Sensitive paper (SP) (see Section 4.12) size distribution testing was
conducted once at this sampling location. Sensitive papers of 47 diameter
were exposed at each test point. Exposure times were selected to produce
samples with a sufficient number of stains to allow confidence in the resultant
droplet size distribution while avoiding overlapping stains. Local updraft air
velocity values were taken at each sampling point using a Gill propeller
anemometer and a Fluke digital multimeter.
Absorbent paper (AP) and ion exchange paper (XP) (see Section 4.13) samples
were collected during each run at various sampling points.
4.3 COOLING TOWER NO. 68 RECIRCULATING WATER PIPES (SAMPLING LOCATION C)
Circulating water flow rate was determined by traversing the hot water
riser pipe of each riser cell tested using a calibrated pitot tube. A complete
traverse was made initally on each recirculation pipe and then a subsequent
single point check was made prior to each run. The single point check was
considered sufficient if the measured value was within 10% of the value
determined by the initial complete traverse. If the measured value was over
+ 10% of the initial value, a complete traverse was performed again. The pitot
tube traverse procedure and calibration data can be found in Appendices C and
D, respectively.
During each emissions test run, a recirculating cooling water sample was
taken from the hot water riser pipe of each riser cell tested. These samples
were taken by hand and stored in 500 ml glass jars. Each sample was analyzed
by RTI for hexavalent chromium (wet chemical method) and total soluble chromium
by ICAP. Aliquots of each water sample were filtered through 1.0 um Teflon
filters. Both the filter residue and the filtrate were analyzed by NCSU for
total chromium by neutron activation analysis (NAA).

4.4 COOLING TOWER NO. 84 OUTLETS, COUNTERFLOW RISER CELLS A, B, C, AND D,
HIGH EFFICIENCY DRIFT ELIMINATORS (SAMPLING LOCATION D)
Emissions testing for determination of chromium and drift emissions and
drift size distribution using several methods was conducted at each of four fan
cells on the counterflow cooling tower No. 84. A schematic of the sampling
locations for cooling tower No. 84 is shown in Figure 4.2. As shown in Figure
4.2, there is only one fan cell associated with each riser cell.
The fan cell stacks were identical in construction, approximately 24 feet
in diameter at the plane of the fan blade, and 18 feet in height. Sampling
probes connected to sampling train boxes containing impingers and filter were
introduced into the fan cell exhausts and were suspended from a monorail to
facilitate traversing the stack. The cell stacks were 287 inches in diameter
at the plane of the nozzle and train. The propeller anemometer used to measure
the axial component of the exhaust gas flow was located 3 to 5 inches above the
sampling point.
A Method 13~type impinger train was used for chromium and drift emissions
sample collection. Each fan cell stack was traversed along one axis at 12
points following the draft method (Appendix C). Each of the twelve points was
sampled for 10 minutes for a total sampling time of 120 minutes per run. Two
runs were conducted per fan cell stack with two of these runs (one on riser
cell A and one on riser cell C, see Figure 4.2) having the impinger contents
and filter recovered separately for an efficiency check.
Paired train test runs using the "disc" and "aligned nozzle" particle
sizing trains (see Section 4.11) were also conducted. One such run was
conducted at a single point over the fan cell stack of riser cell A and the
other was conducted at a single point over riser cell D. Both paired train
runs were 240 minutes in length.

Absorbent paper (AP) and ion exchange paper (XP) (see Section 4.13) samples
were collected during each run at various sampling points.
4.5 COOLING TOWER NO. 84 RECIRCULATING WATER PIPES (SAMPLING LOCATION E)
Circulating water flow rate was determined by traversing the hot water
riser pipe of each riser cell tested using a calibrated pitot tube. A complete
traverse was made initially on each recirculation pipe and then a subsequent
single point check was made prior to each run. The single point check was
considered sufficient if the measured value was within 10% of the value
determined by the initial complete traverse. If the measured value was over
+ 10% of the inital value, a complete traverse was performed again. The pitot
tube traverse procedure and calibration data can be found in Appendices C and
D, respectively.
During each emissions test run, a recirculating cooling water sample was
taken from the hot water riser pipe of each riser cell tested. These samples
were taken by hand and stored in 500 ml glass jars. Each sample was analyzed
by RTI for hexavalent chromium (wet chemical method) and total soluble chromium
by ICAP. Aliquots of each water sample were filtered through 1.0 um Teflon
filters. Both the filter residue and the filtrate were analyzed by NCSU for
total chromium by neutron activiation analysis (NAA).

4.6	AMBIENT METEOROLOGICAL STATION
A portable meteorological station was assembled and operated continuously
on the ground approximately 100 feet from each cooling tower tested to monitor
ambient conditions at the time of sampling. Wind speed and direction were
measured using a cup anemometer and directional anemometer. Ambient wet
bulb/dry bulb temperatures were obtained using a psychrometer. Meteorological
data collected are summarized in Chapter 2.
4.7	VELOCITY AND GAS TEMPERATURE
A propeller anemometer was used to determine the total flow velocity in the
axial direction at each sampling point as described in the draft test method
(see Appendix C). The temperature at each sampling point was measured using a
thermocouple and digital readout.
4.8	MOLECULAR WEIGHT
Flue gas composition was essentially that of the ambient air drawn into the
cooling tower via the fan. Therefore, the dry molecular weight and composition
of air was used.
4.9	CHROMIUM COLLECTED BY IMPINGER TRAINS
Method 5_type sampling procedures, as described in the Federal Register,*
were used with the Method 13~type trains to measure chromium and drift
emissions at each emissions sampling location (see the draft test method in
Appendix C). Sampling trains consisted of a heated, glass-lined probe and a
series of Greenburg-Smith impingers (two containing 100 ml of deionized-
distilled water, one empty, and one with silica gel) with a 3~inch nominal
*40 CFR 60, Appendix A, Reference Methods 2, 3. and 5. July 1, 1980.
4-10
-------
Teflon filter located between the third and fourth impinger. A deionized-
distilled water rinse of the nozzle, probe, appropriate filter holder portions,
and impingers of the sampling train was made at the end of each test. This
rinse, the impinger contents, and the filter were combined and stored in a
500 ml glass jar, except for the four sampling runs on which collection
efficiency checks were made. For these four runs, the rinse, impinger
contents, and filter were stored and analyzed separately.
The samples were typically concentrated to approximately 25 ml in a 500 ml
glass beaker and then were transferred to another container. The 500 ml
beakers used to concentrate the samples were treated with aqua regia to
solubilize residual chromium and these solutions were treated as separate
samples. The total chromium content of the impinger samples (after solubili-
zation of the chromium with nitric acid) and the total chromium content of the
solution containing the residual chromium from the beakers was determined by
RTI using graphite furnace atomic absorption (GFAA). The total chromium catch
for each impinger run is the sum of the total chromium content in the
corresponding impinger sample and the total chromium content solubilized from
the appropriate beaker using aqua regia.
4.10 CHROMIUM IN COOLING WATER
Cooling water samples collected were analyzed by RTI for hexavalent
chromium using the diphenylcarbazide wet chemical method. Also, a 10-ml
aliquot of the cooling water was filtered through a Teflon filter with a 1.0-um
pore size, and the residue (trivalent chromium) and the filter were analyzed
for total chromium by NAA. A flow chart for the analysis of cooling water
samples is presented in Figure 4.3-
4-11

-------
4.11	DRIFT SIZING USING ALIGNED NOZZLE AND DISC TRAINS
Paired aligned nozzle and disc trains were used to estimate the percent
chromium in drift particles smaller than a certain size. The disc train
consisted of the impinger train set-up described in Section 4.9 with the
exception that no nozzle was attached to the probe and a plexiglass disc was
attached in the plane of the flow around the opening of the probe. This
configuration was designed to collect the majority of drift particles less than
a certain diameter.
The aligned nozzle train was run at the same time as the disc train at the
same single sampling point to serve as a reference measurement for collection
of all sizes of drift particles. It was identical to the impinger train used.
The nozzle was aligned directly with the flow at the point sampled; the exact
flow direction and delta P at that point was determined using a three-dimen-
sional pitot tube.
The catches from each train were analyzed as previously described for the
chromium emissions and drift testing.
4.12	SENSITIVE PAPER TESTING
Sensitive paper (SP) testing was used to measure drift rate and size
distribution. The SP testing relies on droplet collection by inertial
impaction on water-sensitive paper held perpendicular to the flow. This paper
is chemically treated so the impinging droplet generates a well-defined blue
stain on the pale yellow background of the paper. The size and shape of the
stain and the droplet size were correlated by calibrating the SP system with a
mono-disperse water droplet generator over a range of droplet sizes and
impaction velocities.
Processing of exposed SP's consisted of measuring the stain diameters using
a microscope and a semi-automated GRAF PEN digitizer linked to a microcomputer
4-13
-------
which groups stain counts by size range. A computer program employing
calibration curves for specific droplet sizes and impaction velocities was used
to correlate stains with their original droplet sizes. In addition, a
correction factor was applied which incorporated the collection efficiency of
each droplet size range.
4.13 ABSORBENT PAPER AND ION EXCHANGE PAPER TESTING
Absorbent paper (Whatman™ 541 filter paper) held in a sensitive paper
sampling device was attached to each traversing impinger train to collect drift
emissions. This was part of an effort to evaluate screening techniques for
cooling tower testing. The sensitive paper device and absorbent paper were
positioned on the probe of the impinger train and were exposed so as to collect
drift emissions during the 120 minutes of impinger train sampling. Absorbent
paper samples were analyzed for total chromium by NAA.
Ion exchange paper (Schleicher and Schuell™ DEAE (Diethylaminoethyl)
cellulose membrane filter paper) was also used in the SP device to collect
drift emissions as part of the effort to evaluate screening techniques for
cooling towers. The positively charged papers were exposed at traverse points
as well as at single stationary points in order to collect ions entrained in
the drift emissions. The ion exchange paper samples were analyzed for total
chromium by NAA.
4-14

5.0 QUALITY ASSURANCE
Because the end product of testing is to produce representative emission
results, quality assurance is one of the main facets of stack sampling.
Quality assurance guidelines provide the detailed procedures and actions
necessary for defining and producing acceptable data. Two such documents were
used in this test program to ensure the collection of acceptable data and to
provide a definition of unacceptable data. These documents are the EPA Quality
Assurance Handbook Volume III, EPA-600/4-77-027 and Entropy's "Quality
Assurance Program Plan," which has been approved by the U. S. EPA, EMB.
Relative to this test program, the following steps were taken to ensure
that the testing and analytical procedures produce quality data.
• Calibration of field sampling equipment. (Appendix D describes
calibration guidelines in more detail.)
o Checks of train configuration and calculations.
« On-site quality assurance checks of sampling train components.
o Use of designated analytical equipment and sampling reagents.
Pre- and post-test calibrations were performed for each of the meter boxes
used for sampling. Calibrations were also performed for the temperature
sensing equipment, nozzles, water flow pitot tubes, anemometer sensor, and the
entire propeller anemometer apparatus. Appendix D includes the calibration
data sheets for each dry gas meter used for testing and data sheets for the
calibrations of the other sampling equipment mentioned.

An on-site audit was performed on the meter boxes used for sampling and
the data are summarized in Table 5-1- Entropy used the procedures described
in the December 14, 1983 Federal Register (48F255670).

DRAFT METHOD - 6/19/86	^ C^iiJ

METHOD^/- direct measurement of gas velocity and volumetric flowrate
UNDER CYCLONIC FLOW CONDITIONS (PROPELLER ANEMOMETER)
1.	Applicability and Principle
1.1	Applicability. This method applies to the measurement of gas
velocities in locations where cyclonic flow conditions exist and gas
temperatures range from 0° to 50°C (e.g. cooling tower exhausts).
1.2	Principle. A propeller anemometer is used to measure gas velocity
directly. Tne area of the stack cross section at the sampling location is used
to calculate volumetric flowrate, and temperature and pressure measurements are
used to correct volumes to standard conditions.
2.	Apparatus
Specifications for the apparatus are given below.
2.1	Propeller Anemometer. A vane axial propeller anemometer capable of
measuring gas velocities to within 2 percent. The manufacturer's recommended
range (all-angle) shall be sufficient for the expected minimum flow rates at
the sampling conditions. Temperature, pressure, moisture, corrosive
characteristics, and sampling location are factors necessary to consider in
choosing a suitable propeller anemometer.
2.2	Data Output Device. A digital voltmeter, analog voltmeter, stripchart
recorder, data-logger, or computer capable of displaying propeller anemometer
output to within 1 percent and at a minimum frequency of 1 reading per minute.
2-3 Temperature Gauge. Same as Method 2, Section 2.3 for volume
correction to standard conditions.
Z.b Barometer. Same as Method 2, Section 2.5 for volume correction to
standard conditions.
2.5 Calibration Equipment.
2.5-1 Synchronous Motor. A variable speed synchronous motor capable of
providing a known constant rotational speed to the input shaft of the propeller
anemometer for purposes of comparing and adjusting the output signal to known
values.
2.5-2 Bearing Torque Disc. A variable torque applicator capable of
applying a range of torques to the input shaft of the propeller anemometer from
0 to the manufacturer's recommended "poor performance" criterion.
C-3
-------
2.5-3 Wind Tunnel. A wind tunnel capable of providing stable velocities
over the expected range of velocities to be measured. Air flow should be fully
developed turbulent flow in the axial direction only. Means shall be available
to quantify ambient temperature and pressure for correction to standard
conditions. Means shall also be available to rotate the propeller anemometer,
within the wind tunnel, through 180° (*90° of the centerline) and note the
_	, _o
angle of rotation m 10 increments.
2.5.4 Calibration Pitot Tube. Same as Method 2, Section 2.7 for
determination of wind tunnel velocities to within 1 percent.
2.5-5 Differential Pressure Gauge for Calibration Pitot Tube. Same as
Method 2, Section 2.8 for use with the standard pitot tube during wind tunnel
velocity determinations.
3. Procedure
3.1 Proper Mounting of Propeller Anemometer. Attach the propeller
anemometer to e suitable device (probe, rail, roc, etc.) to facililtate
traversing the stack/duct cross-section. Ensure that all flow obstructions
created by (1) the sampling support equipment (rail, etc.) are a minimum of 2
propeller diameters downstream of the propeller and (2) the sampling equipment
(nozzles) are a minimum of 2 inches upscream of the propeller and have a
maximum obstructive aree (projected area) 1C« the size of the propeller's area
of rotation. Ensure that the propeller anemometer is properly aligned with the
centerline of the stack/duct and stably mounted (vibration and subsequent
misalignment will create serious errors in the velocity and volumetric flow
rate results). Connect electrical connections for velocity data recording as
shown in Figure fjy-1.
3-2 Cross Sectional Area. Determine the stack/duct dimensions at the
sampling location. Include the total area (at the sampling location) without
regard to the velocity in the stack.
3-3 Zero Output System. Zero all recording devices by carefully bringing
the propeller anemometer to a stand-still. Record ambient temperature and
pressure data and note time and date as shown in the example data sheet
Figure?^ -2.
3-4 Determination of Gas Velocity. Measure the gas velocity and
temperature at the traverse points specified by Method 2^ or other applicable
method. (Note: Due to the size of most propellers, traverse points within 10
cm of a side-wall will be unmeasureable.) Alternatively, based on the
preliminary traverse or the previous measurement, the stack temperature may be

measured at a single point if the gas temperatures at all points were within
5°F of the average temperature.
k. Calibration
k.l Propeller Anemometer. The propeller anemometer shall be calibrated
before its initial use in the field. Both electro/mechanical and performance
parameters shall be checked during calibration according to the procedures
supplied by the manufacturer. Calibration procedures in . 1.1, *1.1.2 and *{.1.3
shall be conducted before the initial field use. Calibration procedures in
*4.1.3 shall be conducted for each propeller m use and whenever the structural
integrity of a propeller or shaft/generator housing is in question.
*1.1.1 Generator Output Test. To assess the integrity of the electrical
output, a variable speed synchronous motor to rotate the propeller anemometer
input shaft at known rotational velocities will be required. A minimum of two
speeds shall be used to check the electrical output of each shaft/generator
housing. The two speeds chosen shall fall on either side of the expected shaft
velocities under field use.
Couple the synchronous motor to the anemometer input shaft according to the
manufacturer's specifications (to ensure no slippage occurs). Attach an output
device to the anemometer electrical outputs and start motor. Obtain the first
rotational test speed and record the anemometer output in either mV DC or rpm.
Obtain the second rotational test speed and record the anemometer output.
Continue with additional rotational test speeds if applicable. Repeat each
test speed in order to obtain a total of three output readings for each speed.
Average the three output readings from each rotational test speed applied
ana compare these results with the manufacturer's specifications (e.g., linear
rpm/mV ratio). Results should compare with specifications to within 2 percent.
*j.l.2 Bearing Torque Test. To assess the integrity of the mechanical
bearings supporting the input shaft, a bearing torque test snail be conducted.
Attach to the anemometer input shaft a torque applicator (e.g., bearing torque
disc) which will apply a range of known, repeatable torques beyond the
manufacturer's "poor performance" criterion. Starting with a 0.1 gm-cm torque,
continually increase the applied torque in 0.1 gm-cm increments until the shaft
begins to turn. Record the applied torque required to create shaft rotation
and repeat two times. Results from all three tests should be below the
manufacturer's specification for "poor performance." Conduct this check after
the non-axial flow calibration to document the torque required during the
calibration.

*1.1.3 Non-Axial Flow Test. Assess the representativeness of
manufacturer's angular flow calibration curve by conducting a wind tunnel test
on each propeller in use and generating a percent response-vs-wind angle curve
for comparison. Attach the propeller anemometer to the wind tunnel to allow a
full 180° rotation {*90° from the center line) within the tunnel. Connect all
other apparatus to display/record anemometer outputs.
With the wind tunnel operating at 15 to 25 fps, determine the velocity at
the propeller location using a standard pitot, differential pressure gauge,
barometric pressure and temperature. Starting with the propeller anemometer
oriented into the direction of flow (0°) rotate ana record the output readings
at 10° increments from 0° to f 90° and 0° to - 90°. Plot these results on a
percent response-vs-wind angle graph and compare to the manufacturer's
specifications. Differences should be within 3 percent at each point for the
1002 axial flow response. Using the 100".' axial flow response compute a
velocity result and compare it to the velocity results measured using the
standard pitot probe. This difference should be within 3 percent of the pitot
probe results at 0°. Repeat this test at a velocity of 25 to ^40 fps; compute
the percent deviations as above.
Note: If the results of the propeller anemometer initial calibration tests
are not within the required specifications, then either corrective maintenance
should be implemented to correct the deficiencies or the equipment m question
should be considered unsatisfactory and replaced.
4.1.^ Field Use and Recalibration.
*1.1.^.1 Field Use. When the propeller anemometer is used in the field,
the manufacturer's electromechanical ratio and axial/rotational velocity ratio
shall be used to perform the velocity calculations.
k.l.k.2 Recalibration. After each test run, both a bearing torque check
and a generator output test shall be conducted. If the bearing torque check is
more than twice the torque recorded after calibration or is m the range of
"poor performance" as described by the manufacturer, the anemometer must be
repaired or replaced and the run repeated. The generator output test results
must be within 5 percent of the predicted value or the system must be repaired
or replaced and the run repeated. -Alternatively the tester may opt to conduct
both checks at the conclusion of all runs. However, if both criteria are not
met, all runs must be repeated.
If both checks meet the above criteria and a visual inspection of the
propeller shows no apparent changes, no additional calibrations must be
conducted. Whenever the propeller anemometer fails to meet either of the
C-8
-------
above requirements or the propeller becomes damaged, a complete recalibration
as described in 4.1.1, 4.1.2 and 4.1.3 must be conducted.
4.2	Temperature Gauge. After each test series, check the temperature
gauge at ambient temperature. Use an American Society for Testing and
Materials (ASTM) mercury-in-glass reference thermometer, or equivalent, as a
reference. If the gauge being checked does not agree within 2 percent
(absolute temperature) of the reference, the temperature data collected in the
field shall be considered invalid or adjustments of the test results shall be
made, subject to the approval of the Administrator.
4.3	Barometer. Calibrate the barometer used against a mercury barometer
prior to the field test as described in Method 2.

beyond that of the acquired data. Round off figures after the final
calculation.

DRAFT METHOD - 1/23/87
METHOD tT - DETERMINATION OF CHROMIUM EMISSIONS
FROM COOLING TOWERS
1.	Applicability and Principle
1.1	Applicability. This method applies to the determination of total
chromium and hexavalent chromium (Cr+^) emissions from cooling towers. The
hexavalent chromium emissions are calculated from the total chromium mass
emission rate using the ratio of hexavalent-to-total chromium in the cooling
water.
1.2	Principle. Chromium emissions are collected from the exit of the
cooling tower cell(s) using an impinger train for sample collection and the
propeller anemometer for velocity measurement. The impinger train is the
same design as described in EPA Method 13 with the exception that the filter
*
is made of Teflon™ and a propeller anemometer is used in place of the pitot
tube. The impinger train samples are analyzed for total chromium (1) using
Neutron Activation Analysis (NAA) or (2) by solubilizing all the chromium
using nitric acid and measuring by Graphite Furnace Atomic Absorption (GFAA)
or Inductively-Coupled Argon Plasmography (ICAP). Cooling water samples are
also collected and analyzed both for total chromium by NAA, GFAA, or ICAP and
hexavalent chromium by the diphenylcarbazide colorimetric method. (See
Citations 1, 2, and 3 of Bibliography.)
2.	Range, Sensitivity, Precision, and Interferences
2.1	Range. For a minimum analytical accuracy of + 15 percent, the lower
limit of the range is 0.05 ug total sample catch for chromium. This accuracy
can only be obtained when the analytical laboratory is told that the sample
concentration is extremely low. There is no upper limit.
2.2	Sensitivity. A minimum detection limit of 0.05 ug of Cr should be
observed.
2.3	Precision. The overall precision of the sample collection and
analysis for a tower containing 4 ppm of Cr+^ (4 ug/ml) in the cooling water
and emitting 1 ug/mg Cr+^ is about 35 percent with a 95 percent confidence

-------
interval. A higher chromium content and/or a higher chromium emission rate
should improve the precision. No precision measurements have been made for
towers emitting less chromium. When less chromium is expected, sampling times
should be increased to collect the minimum amount of chromium (0.05 ug).
2.4 Interference. Sodium can interfere with the measurement of chromium
by NAA. Since sodium has a short half-life, the sodium interference can be
minimized by allowing the samples to radiate for approximately 14 days prior
to analysis. In studies conducted by EPA, approximately 100 ppm of sodium in
cooling water did not effect the analytical accuracy.
3.0 Apparatus
3.1 Sampling Train. A schematic of the sampling train used in this
method is shown in Figure C/T-l. Commercial models of this train are
available. All portions of the train that will come into direct contact with
the sample should be cleaned with 1:1 HNO^ and rinsed thoroughly before field
use. After each sample is taken in the field, rinse with 0.1 N HNO^ and
follow with a water rinse.
The operating and maintenance procedures for the sampling train are
described in APTD-0576 (Citation 3 in the Bibliography). The sampling train
consists of the following components:
3-1.1 Probe Nozzle. Stainless steel (316) or glass with sharp, tapered
leading edge. .The angle of taper shall be <30° and the taper shall be on the
outside to preserve a constant internal diameter. The probe nozzle shall be
of the button-hook or elbow design, unless otherwise specified by the
Administrator. If made of stainless steel, the nozzle shall be constructed
from seamless tubing; other materials of construction may be used, subject to
the approval of the Administrator.
A range of nozzle sizes suitable for isokinetic sampling should be
available, e.g., 0.32 to 1.27 cm (1/8 to 1/2 in.)—or larger if higher volume
sampling trains are used—inside diameter (ID) nozzles in increments of 0.16
cm (1/16 in.). Each nozzle shall be calibrated according to the procedures
outlined in Section 6.
3-1.2 Probe Liner. Borosilicate or quartz glass tubing with a heating
system capable of maintaining a gas temperature at the exit end during
sampling of 120 +_ l4°C (248 + 25°F), or such other temperature as specified by
an applicable subpart of the standards or approved by the Administrator for

a particular application. (The tester may opt to operate the equipment at a
temperature lower than that specified.) Since the actual temperature at the
outlet of the probe is not usually monitored during sampling, probes
constructed according to ATPD-O58I (Citation 5 of Bibliography) and utilizing
the calibration curves of APTD-0576 (or calibrated according to the procedure
outlined in APTD-0576) will be considered acceptable.
In potentially explosive atmospheres, the probe shall not be heated. If
the probe is positioned lower than the sample box, a cyclone or equivalent can
be used to collect the condensed water and drift, thus preventing it from
dripping back out of the probe into the fan cell.
Whenever practical, every effort should be made to use borosilicate or
quartz glass probe liners. Metal liners (e.g., 316 stainless) which contain
chromium are not allowed.
3.1.3 Propeller Anemometer. A.propeller anemometer as described in
Section 2.1 of Method PA_, or other device approved by the Administrator. The
propeller anemometer shall be attached to the sampling train (as shown in
Figure TA-1) to allow constant monitoring of the stack gas velocity. The
center of the propeller anemometer shall be placed 2 to 4 inches directly above
the nozzle and aligned with the nozzle opening. The propeller anemometer shall
have known electromechanical and axial/rotational velocity ratios which have
been verified during calibration (see Section 4 of Method?/\ ).
3.1.^1 Data Output Device. A digital or analog millivolt meter, stripchart
recorder, data-logger, or computer as described in Section 2.2 of Method 7A .
This output device shall be used for the measurement of the voltage output from
the propeller anemometer.
3-1-5 Impingers. Four impingers connected as shown in Figure C.T-1 with
ground-glass (or equivalent), vacuum-tight fittings. For the third and fourth
impingers, use the Greenburg-Smith design, modified by replacing the tip with a
1.3 cm inside diameter (1/2 in.) glass tube extending to 1.3 cm (1/2 in.) from
the bottom of the flask. For the second impinger, use a Greenburg-Smith
impinger with the standard tip. The tester may use modifications (e.g.,
flexible connections between the impingers or materials other than glass),
subject to the approval of the Administrator. Place a thermometer, capable of
measuring temperature to within 1°C (2°F), at the outlet of the fourth impinger
for monitoring purposes.
C-14
-------
3.1.6	Filter Holder. Borosilicate glass, with a glass frit filter support
and a silicone rubber gasket. Other materials of construction (e.g., Teflon™,
Viton) may be used, subject to the approval of the Administrator. The holder
design shall provide a positive seal against leakage from the outside or around
the filter. The holder shall be attached between the third and fourth impinger.
3.1.7	Forceps. Plastic.
3.1.8	Metering System. Vacuum gauge, leak-free pump, thermometers capable
of measuring temperature to within 3°C (5*^°F)> dry Sas meter capable cf
measuring volume to within 2 percent, and related equipment, as shown in
Figure CT-1. Other metering systems capable of maintaining sampling rates
within 10 percent of isokinetic and of determining sample volumes to within 2
percent may be used, subject to the approval of the Administrator. When the
metering system is used in conjunction with a propeller anemometer, the system
shall enable checks of isokinetic rates.
Sampling trains utilizing metering systems designed for higher flow rates
than that described in APTD-O58I or APTD-0576 may be used provided that the
specifications of this method are met.
3.1.9	Barometer. Mercury, aneroid, or other barometer capable of
measuring atmospheric pressure to within 2.5 mm (0.1 in.) Hg. In many cases,
the barometric reading may be obtained from a nearby national weather service
station, in which case the station value (which is absolute barometric
pressure) shall be requested and an adjustment for elevation differences
between the weather station and sampling point shall be applied at a rate of
minus 2.5 mm (0.1 in.) Hg per 30 m (100 ft) elevation increase or vice versa
for elevation decrease.
3.1.10	Flue Gas Temperature. A temperature sensor as described in Section
2.3 of Method ?A . The temperature sensor shall be attached to the sampling
probe in a configuration such that the tip of the sensor extends beyond the
leading edge of the probe sheath, does not touch any metal, and is in an
interference-free arrangement with the nozzle. As an alternative (as described
in Method PA ), if all points are within 5°F of the average stack temperature,
the temperature of the stack may be determined at a single point.
3.1.11	Cooling Water Sample Bottle. A glass or polyethylene bottle 25 ml
or greater is required to collect a cooling water sample during each run.
Clean with 1:1 HNO^ and rinse thoroughly before use.
3.1.12	Equipment for Sampling in Potentially Explosive Areas. Class I
Division 1 Locations: Currently available equipment cannot be readily modified
for use in Class I Division 1 locations.
C-15
-------
Class I Division 2 Locations: Two gas monitors are required to continu- •
ously monitor the atmosphere both at the cooling tower discharge point and the
area around the meter box. The gas monitors must be of the continuous type
(LEL meters or similar devices) and equipped with an alarm that indi- cates
when 40 percent of the lower explosive limit (LEL) has been reached. The meter
box must be equipped with an explosion-proof switch to shutdown all power to
the box in case of an emergency. The electrical cord running to the meter box
must be SO-type line and must be equipped with an explosion-proof plug.
3-2 Sample Recovery. Clean all items for sample handling or storage
with 1:1 HNO^ and rinse thoroughly before use. The following items are
needed:
3.2.1	Probe-Liner and Probe-Nozzle Brushes. Nylon bristle brushes with
a handle (at lieast as long as the probe) of Nylon, Teflon™, or a similar
material which does not contain chromium. The brushes shall be properly
sized and shaped to brush out the probe liner and nozzle.
3.2.2	Wash Bottles—Two. Glass wash bottles are recommended;
polyetheylene wash bottles may be used at the option of the tester.
3.2.3	Glass Sample Storage Containers. Chemically resistant, boro-
silicate glass bottles, for water washes, 500-ml or 1000-ml. Screw cap
liners shall either be rubber-backed Teflon™ or shall be constructed so as to
be leak-free. (Narrow mouth glass bottles have been found to be less prone
to leakage.) Alternatively, polyethylene bottles may be used.
3.2.4	Forceps. Plastic.
3.2.5	Graduated Cylinder and/or Balance. To measure condensed water to
within 1 ml or 1 g. Graduated cylinders shall have subdivisions no greater
than 2 ml. Most laboratory balances are capable of weighing to the nearest

Section 5"7o.2. .
3.2.6	Plastic Storage Containers. Air-tight containers to store silica
gel.
3.2.7	Funnel ar.i Rubber Policeman. To aid in transfer of silica gel to
container; not necessary if silica gel is weighed in the field.

C-16
-------
3-3 Sample Preparation for Analysis. Clean all items for sample handling or
storage with 1:1 HNO^ and rinse thoroughly before use. The following items
are needed:
3.3.1	Beakers. Borosilicate glass in sizes adequate for concentrating
aqueous samples (600-ml or larger) and digesting cooling water residue
filters (25- to 50-ml)•
3.3.2	Hot Plate.
3.3.3	Storage Vials. Borosilicate glass, 40-ml capacity, with cap and
Teflon™ liner, such as EPA-approved vials for water analysis.
3.3.4	Analytical Balance. To measure within 0.1 mg.
3.3.5	Vacuum Filter Unit. Plastic or glass, 47-mm in diameter.
3.3.6	Graduated Cylinder. In a size slightly larger than size of
cooling water sample bottles.
3-3-7 Glass Sample Storage Containers. Same as 3-2.3-
3.3*8 NAA Vials (Optional). For NAA of cooling water residue only. The
laboratory conducting the NAA analysis should be contacted and the proper
screw-type vials obtained for the filters used to collect the residue.
3-4 Analysis. Three analytical methods have presently been shown to be
satisfactory for analysis of total chromium in cooling tower samples: GFAA,
ICAP, and NAA. One of these methods is used for the analysis of the impinger
train samples and the residue portion of of the cooling water samples.
(Additional specifications will be added to this section upon final selection
of the analytical method.) Analysis for hexavalent chromium in the cooling
water samples is performed following the Draft Method - "Determination of
Hexavalent Chromium Emissions from Stationary Sources." The necessary
apparatus is listed in Section 3-3 of the method.
4. Reagents
Unless otherwise indicated, all reagents must conform to the speci-
fications established by the Committee on Analytical Reagents of the American
Chemical Society. Where such specifications are not available, use the best
available grade.
4.1 Sampling. The reagents used in sampling are as follows:
4.1.1 Water. Approximately 300 to 400 ml of deionized water for
impinger reagent and for sample cleanup; deionized water is also required for
reagent preparation. Significant levels of chromium must not be present in
the water. It is recommended that water blanks be checked prior to sampling
to ensure that the chromium content is less than 0.1 part per billion (0.1 ug
C-17
-------
per liter); this can be accomplished by concentrating one liter of the water and .
analyzing by the appropriate technique.
4.1.2 Filters. Teflon™ or equivalent filters with 0.5~niicron or smaller
pore size. The filter must have a chromium blank value of less than 0.005 ug
chromium per filter. Many glass fiber filters exceed the limit for chromium and
should not be used.
4.2	Sample Recovery. The reagents used in sample recovery are as follows:
4.2.1	Water. Approximately 300 to 400 ml of distilled water for impinger
reagent and sample cleanup; significant levels of chromium must not be present
in the water. (See Section 4.1.1.)
4.2.2	Nitric Acid, 0.1 N. Slowly add 7 ml of concentrated nitric acid
(HNO^) to water in a 1-liter flask; dilute to the mark.
4.3	Sample Preparaton and Analysis. As previously noted in Section 3-^.
three analytical methods are presently believed satisfactory for analysis of
total chromium in the impinger train samples and the cooling water sample
residues. The Draft Method for Hexavalent Chromium is used to measure the
hexavalent chromium in the cooling water filtrate. The reagents needed to
prepare the impinger train samples and cooling water aliquots for total chromium
analysis are listed below. The reagents necessary for the hexavalent chromium
analysis of the cooling water filtrate are listed in Section 4.3 of the Draft
Method. (Additional specifications for reagents needed for total chromium
analysis will be added to this section upon final selection of the analytical
method.)
4.3-1 Water. See Section 4.1.1.
4.3-2 Nitric Acid. Concentrated.
4.3-3 Nitric Acid, 1:1 (v/v). Slowly add an equal volume of concentrated
nitric acid (HNO^) to water.
4.3-4 Filters. Teflon, 1.0-um pore size, 47-mm diameter for collecting
insoluble residue in cooling water.
4.3-5 Aqua Regia. Slowly add 1 part of concentrated nitric acid to 3 parts
concentrated sulfuric acid.
4.3.6 Performance Audit Sample. A performance audit sample shall be
obtained from the Quality Assurance Division of EPA and analyzed with the field
samples. The mailing address to request the samples is:

5. Procedure
5.1 Sampling. The complexity of this method is such that to obtain
reliable results, testers should be trained and experienced with the test
procedures.
5.1.1 Pretest Preparation. All the components shall be maintained and
calibrated according to the procedure described in APTD-0576, unless
otherwise specified herein.
Weigh several 200- to 300-g portions of silica gel in air-tight
containers to the nearest 0.5 g. Record the total weight of the silica gel
plus container, on each container. As an alternative, the silica gel need
not be preweighed, but may be weighed directly in its impinger or sampling
holder just prior to train assembly.
Check filter visually against light for irregularities and flaws or
pinhole leaks. Label filters of the proper diameter on the back side near
the edge using numbering machine ink. Alternatively, the filter holder, or
other means of tracking the filter to ensure that the filter is recovered
with the proper sample, may be used. The filters are not preweighed since
the analysis is a chemical determination.
5-2 Determination of Measurement Site. Due to the configuration of
cooling towers, Method 1 cannot be used to determine measurement sites.
Following are several alternatives for determining measurement sites for
cooling towers.
5.2.1	Selection of Number of Fan Cells to be Tested. For towers with
three or less cells, all cells shall be tested. For towers with 4 or 5
cells, at least 3 cells shall be tested. For towers with 6 or more fan
cells, a minimum of half of the cells shall be tested.
5.2.2	Criteria for Selecting Cells and Traverse Direction. The
following criteria must be met:
(a)	Every run must consist of two traverses.
(b)	Every equal area cell must be represented by at least two runs.
(c)	A single traverse direction may be used for all towers containing
more than one cell.
(d)	Based on the prevailing winds, the extreme inward and outward cells
are initially identified and selected for sampling.
(e)	After identifying the extreme inward and outward cells, the
remaining cells to be sampled (sufficient to equal required minimum)
are selected at random.
(f)	The mass emission rate for the tower is the sum of the averages for
each of the equal area cells.
(g)	The traverse direction at the stack exit may be selected by the
tester.
C-19
-------
(h)	The order for sampling the cells may be selected by the tester.
(i)	All runs must be consecutive; none may be conducted simultaneously,
(j) When a tower contains two distinctly different types of mist
eliminators, the cells with different mist eliminators must be
considered in the same manner as if the cells have different areas.
The following six examples are given to better define the approach for
selecting the cells to be sampled. Circles represent fan cells, the small
rectangles show the recommended location for scaffolding, and the dotted
lines indicate traverse directions. Cells on towers with multiple fan cells
are selected in pairs to reduce the amount of scaffolding needed to conduct
the testing. The order of the sample runs and traverses presented are only
examples and the order is left to the tester.

5.2.3 Criteria for Selecting Traverse Points. The following criteria
must be met:
C-23
-------
(a)	The traverse line may be located in any plane near the exit of the
cell. The tester may alternatively select any plane that is not
affected by the wind to a greater degree than the cell exit plane
(i.e., for a large cells—an access door in the cell stack or a
point 2 feet above the cell on a calm day).
(b)	Twelve points shall be sampled on each traverse for a minimum of 5
minutes per point. The points shall be located on the traverse line
at the percentage of the diameter as shown below:
Point 1	-	2.1%	Point 2 - 6.7%	Point 3 - 11.8%
Point 4	-	11.1%	Point 5 -25.0%	Point 6 — 35•6%
Point 7	-	63-4%	Point 8 - 75-0%	Point 9 - 82.3%
Point 10 -	88.2%	Point 11 - 93-3%	Point 12 - 97.9%
(c)	No point shall be closer than 9 inches from the wall. All points
that are calculated at less than 9 inches from the wall shall be
relocated at 9 inches from the wall.
5-3 Preliminary Determinations. Select the cells and the sampling
points as described in Section 5-2. Determine the stack pressure,
temperature and the range of velocities using Method PA • Determine the
moisture content with a wet and dry bulb thermometer, or assume saturation at
the stack temperature and calculate the moisture.
Select a nozzle based on the range of velocities, such that it is not
necessary to change the nozzle size in order to maintain isokinetic sampling
rates. During the run, do not change the nozzle size.
Select a total sampling time greater than or equal to the minimum total
sampling time based on 5 minutes per point and 2 hours per run.
The sampling time at each point shall be the same. It is recommended
that the number of minutes sampled at each point- be an integer or an integer
plus one-half minute, in order to avoid timekeeping errors.
5.4 Preparation of Collection Train. Clean all portions of the sampling
train which will come into direct contact with the sample with 1:1 HNO^ and
rinse thoroughly with water. During preparation and assembly of the sampling
train, keep all openings where contamination can occur covered until just
prior to assembly or until sampling is about to begin.
Place 100 ml of water in each of the first two impingers, leave the third
impinger empty, and transfer approximately 200 to 300 g of preweighed silica
gel. from its container to the fourth impinger. More silica gel may be used,
but care should be taken to ensure that it is not entrained and carried out
from the impinger during sampling. Place the container in a clean place for
later use in the sample recovery. Alternatively, the weight of the silica
gel plus impinger may be determined to the nearest 0.5 g and recorded.
c-24
-------
Using plastic forceps or clean disposable gloves, place a labeled
(identified) filter in the filter holder. Be sure that the filter is
properly centered and the gasket properly placed so as to prevent the sample
gas stream from circumventing the filter. Check the filter for tears after
assembly is completed.
A glass liner or equivalent must be used. Install the selected nozzle
using a Viton A O-ring or Teflon™ ferrules. Mark the traverse monorail or
other system to denote the proper distance in the exit plane of the cells for
each traverse run with equal diameter cells.
Set up the train as in Figure CT~1. using (if necessary) a very light
coat of silicone grease on all ground glass joints, greasing only the outer
portion (see APTD-0576) to avoid possibility of contamination by the silicone
grease.
Place crushed ice around the impingers.
5.4.1 Leak-Check Procedure.
5.4.1.1	Pretest Leak-Check. A pretest leak-check is recommended, but
not required. If the tester opts to conduct the pretest leak-check, the
following procedure shall be used.
After the sampling train has been assembled, leak-check the train at the
sampling site by plugging the nozzle and pulling a 380 mm (15 in.) Hg vacuum.
Note: A lower vacuum may be used, provided that it is not exceeded during
the test.
The following leak-check instructions for the sampling train described in
APTD-0576 and ATPD-O58I may be helpful. Start the pump with bypass valve
fully open and coarse adjust valve completely closed. Partially open the
coarse adjust valve, and slowly close the bypass valve until the desired
vacuum is reached. Do not reverse direction of bypass valve; this will cause
water to back up into the probe. If the desired vacuum is exceeded, either
leak-check at this higher vacuum or end the leak-check as shown below, and
start over.
When the leak-check is completed, first slowly remove the plug from the
inlet to the nozzle, and immediately turn off the vacuum pump. This prevents
the water in the impingers from being forced backward into the probe and
silica gel from being entrained backward into the filter holder.
5.4.1.2	Leak-Checks During Sample Run. If, during the sampling run, a
component (e.g., filter assembly or impinger) change becomes necessary, a
leak-check shall be conducted immediately before the change is made. The
C-25
-------
leak-check shall be done according to the procedure outlined in Section
5.^.1.1 above, except that it shall be done at a vacuum equal to or greater
than the maximum value recorded up to that point in the test. If the leakage
rate is found to be no greater than 0.00057 m /min (0.02 cfm) or 4 percent of
the average sampling rate (whichever is less), the results are acceptable,
and no correction will need to be applied to the total volume of dry gas
metered; if, however, a higher leakage rate is obtained, the tester shall
either record the leakage rate and plan to correct the sample volume as shown
in Section 7-3 of this method, or shall void the sample run.
Immediately after component changes, leak-checks are optional; if such
leak-checks are done, the procedure outlined in Section 5-^-l»l above shall
be used.
5.^.1.3 Post-Test Leak-Check. A leak-check is mandatory at the
conclusion of each sampling run. The leak-check shall be done in accordance
with the procedures outlined in Section ^.k.1.1, except that it shall be
conducted at a vacuum equal to or greater than the maximum value reached
during the sampling run. If the leakage rate is found to be no greater than
0.00057 m /min (0.02 cfm) or 4 percent of the average sampling rate
(whichever is less), the results are acceptable, and no correction need be
applied to the total volume of dry gas metered. If, however, a higher
leakage rate is obtained, the tester shall either record the leakage rate and
correct the sample volume as shown in Section 7-3 of this method, or shall
void the sampling run.
5-4.2 Sampling in Class I Division 2 Locations. The following proce-
dures must be conducted in addition to all plant safety requirements. Plant
regulations take precedent over any requirements stated below. The following
steps must be taken to allow testing at cooling towers in a Class I Division
2 area (as classified in accordance with API RP 500A):
(1)	The plant safety officer must first monitor the area and deem it safe.
(2)	Proper personnel safety equipment must be obtained and properly
utilized during the test.
(3)	A gas monitor (LEL or similar device) must be used to continuously
monitor the atmosphere both at the cooling tower discharge and in the
area around the meter box. Each gas monitor must have an alarm that
is set to indicate when h0% of the lower explosive limit (LEL) is
obtained in either area.
C-26
-------
(4)	The sample collection equipment in the cooling tower discharge stream
must not contain any electrical components with the exception of the
generator in the propeller anemometer which generates less than one
millivolt.
(5)	The electrical cord running to the meter box must be a SO-type line
and must be equipped with an explosion-proof plug.
(6)	The meter box must be equipped with an explosion-proof switch to
shutdown all power in case of an emergency.
(7)	All power to the meter box must be shutdown using the explosion-proof
switch any time the alarm sounds on the LEL meter or the plant alarm
sounds.
(8)	The testers must evacuate the area of the cooling tower if the LEL
alarm sounds and the safety officer must deem the area safe prior to
the return of any testing personnel.
5.^.3 Cooling Tower Operation and Ambient Conditions. Based on
communications with the Cooling Tower Institute (Citation 5 of the
Bibliography), the following guidelines are recommended which relate to tower
operating parameters and ambient environmental conditions during testing:
(1)	Ambient Wind Speed: Ideally the average wind speed during the drift
measurement should be less than 5 to 6 miles per hour. More
realistically, the average wind speed, measured in an open and
unobstructed location within 100 feet upwind of the tower at a point 5
feet above basin curb elevation, should not exceed 10 miles per hour.
Wind gusts should not exceed 15 miles per hour and should not exceed 1
minute duration.
(2)	Heat Load: Measurements may be taken with or without heat load (on a
mechanical draft cooling tower).
(3)	Ambient Temperature and Humidity: Measurements may be taken at any
non-freezing ambient temperature/humidity condition.
(4)	Stability of Test Conditions: Variations in average ambient air
temperatures should not exceed the following limits during the drift
measurement period:
***Wet-bulb temperature - 2°F per hour
***Dry-bulb temperature - 5°F per hour
(5)	Water Flow: The measurements should be taken at normal operating
waterflow conditions, i.e., design flow + 10%.
C-27
-------
(6) Water Quality: Measurements should not be taken during temporary
upset conditions in water chemistry, i.e., the cycles of concentration
for the circulating water at the time of the drift measurement should
be within a reasonable proximity of normal levels.
5-5 Train Operation. During the sampling run, maintain an isokinetic
sampling rate (within 20 percent of true isokinetic unless otherwise specified
by the Administrator).
For each run, record the data required on a data sheet such as the one
shown in Figure CT-2. Be sure to record the initial dry gas meter reading.
Record the dry gas meter readings at the beginning and end of each sampling
time increment, when changes in flow rates are made, before and after each
leak-check, and when sampling is halted. Take other readings required by
Figure cf-2 at least once at each sample point during each time increment and
additional readings when significant changes (20 percent variation in velocity
head readings) necessitate additional adjustments in flow rate.
To begin sampling, position the nozzle at the first traverse point with the
tip pointing parallel to the axis of the fan. Immediately start the pump, and
adjust the flow to isokinetic conditions. Standard isokinetic sampling
nomographs are designed for use with a Type "S" pitot and will have to be
modified for use with the propeller anemometer. Isokinetic sampling rate and
calculation programs using the Hewlett-Packard 4l are available from EPA
(Citation 6 of Bibliography). Traverse the cell as required by Method
If the pressure drop across the filter becomes too high, making isokinetic
sampling difficult to maintain, the filter may be replaced in the midst of the
sample run. It is recommended that another complete filter assembly be used
rather than attempting to change the filter itself. Before a new filter
assembly is installed, conduct a leak-check (see Section 5-4.1.1). The
pollutant catch shall include the summation of all the filter assembly
catches.
At the end of the sample run, turn off the coarse adjust valve, turn off
the pump, remove the probe and nozzle from the stack, record the final dry gas
meter reading, and conduct a post-test leak-check, as outlined in Section
5.4.1.2. Also, conduct a bearing torque check on the propeller anemometer and
a constant rpm check on the electrical system. The torque must not exceed
twice the torque when calibrated. If the torque check does not meet the
requirements, clean and/or replace the propeller anemometer and repeat the
run. Alternatively, the torque check may be conducted after the last run. If

it does not pass, all runs must be repeated. The constant rpm check of the
electrical system must be within 5 percent of the calibration value. If the
system does not meet the requirements, repair or replace the system and void
the run. Alternatively, the check may be conducted after the last run. If it
does not pass, all runs must be repeated.
5-6 Calculation of Percent Isokinetic. Calculate percent isokinetic (see
Calculations, Section 7) to determine whether the run was valid (80 to 120#
isokinetic) or another test run should be made. If there was difficulty in
maintaining isokinetic rates due to source conditions, consult with the
Administrator for possible variance on the isokinetic rates.
5-7 Collection of Cooling Water Sample. A cooling water sample shall be
collected during each run. The sample should be collected once during each
run using a glass or polyethylene bottle from a location that would be
representative of water entering the cooling tower. Alternatively, the tester
may assume that all the chromium in the tower is in the hexavalent state and,
therefore, need not collect cooling water samples to correct the data for
non-hexavalent chromium.
5.8 Sample Recovery. Begin proper cleanup procedure as soon as the probe
is removed from the stack at the end of the sampling period. Wipe off all
external matter near the tip of the probe nozzle and place a cap over it to
keep from losing part of the sample.
Before moving the sampling train to the cleanup site, remove the probe from
the sampling train, wipe off the silicone grease, and cap the open outlet of
the probe. Be careful not to lose any condensate, if present. Remove the
filter assembly, wipe off the silicone grease from the filter holder inlet,
and cap this inlet. Remove the umbilical cord from the last impinger, and cap
the impinger. After wiping off the silicone grease, cap off the inlet to the
first impinger and any open impinger inlets and outlets. The tester may use
ground-glass stoppers, plastic caps, or serum caps to close these openings.
Transfer the probe and filter-impinger assembly to an area that is clean
and protected from the wind so that the chances of contaminating or losing the
sample is minimized.
Inspect the train before and during disassembly, and note any abnormal
conditions. Treat the samples as follows:
5-8.1 Container No. 1 (Probe, Filter, and Impinger Catches). Using a
graduated cylinder, measure to the nearest ml, and record the volume of the
water in the first three impingers; include any condensate in the probe in
C-30
-------
this determination. Transfer the impinger water from the graduated cylinder
into a polyethylene or glass container. Add the filter to this container.
(The filter may be handled separately using procedures subject to the
Administrator's approval.) Taking care that dust on the outside of the probe
or other exterior surfaces does not get into the sample, rinse all
sample-exposed surfaces (including the probe nozzle, probe fitting, probe
liner, first three impingers, impinger connectors, and front half of the
filter holder) with 0.1 N HNO^. Use less than 500 ml for the entire wash.
Add the washings to the sample container. Perform the 0.1N HNO^ rinses as
follows:
Carefully remove the probe nozzle and rinse the inside surface with 0.1 N
HNO^ from a wash bottle. Brush with a nylon bristle brush, and rinse until
the rinse shows no visible particles, after which make a final rinse of the
inside surface. Brush and rinse the inside parts of the Swagelok fitting with
0.1 N HNO^ in a similar way.
Rinse the probe liner with 0.1 N HNO^. While squirting the solution into
the upper end of the probe, tilt and rotate the probe so that all inside
surfaces will be wetted. Let the rinse drain from the lower end into the
sample container. The tester may use a funnel (glass or polyethylene) to aid
in transferring the liquid washes to the container. Follow the rinse with a
probe brush. Hold the probe in an inclined position, and squirt 0.1 N HNO^
into the upper end as the probe brush is being pushed with a twisting action
through the probe. Hold the sample container underneath the lower end of the
probe, and catch all rinse and particulate matter that is brushed from the
probe. Run the brush through the probe three times or more. Rinse the brush
with 0.1 N HNO^, and quantitatively collect these washings in the sample
container. After the brushing, make a final rinse of the probe as described
above: It is recommended that two people clean the probe to minimize sample
losses.
Rinse the inside surface of each of the first three impingers (and connect-
ing glassware) three separate times. Use a small portion of 0.1 N HNO^ for
each rinse, and brush each sample-exposed surface with a nylon bristle brush,
to ensure recovery of fine particulate matter. Make a final rinse of each
surface and of the brush.
After ensuring that all joints have been wiped clean of the silicone
grease, brush and rinse the inside of the filter holder (front-half only) with
0.1 N	Brush ,and rinse each surface three times or more if needed. Make
a final rinse of the brush and filter holder.
C-31
-------
After all 0.1 N HNO^ rinsings have been collected in the sample container,
tighten the lid so that the liquid will not leak out when it is shipped to the
laboratory. Mark tne height of the liquid level to determine whether leakage
occurs during transport. Label the container clearly to identify its
contents.
This cleanup must be conducted for each of the test runs. Between sampling
runs, rerinse all the sample-exposed surfaces of the train and the probe and
impinger brushes with water. Keep brushes clean and protected from
contamination.
5-8.2 Container No. 2 (Sample Blank). Prepare a blank by placing an
unused Teflon™ filter in a container and adding a volume of water and 0.1 N
HNO^ equal to the total volume in Container No. 1. Process the blank in the
same manner as for Container No. 1. Only one sample blank must be collected
for each test series.
5.8.3 Container No. 3 (Silica Gel). Note the color of the indicating
silica gel to determine whether it has been completely spent and make a
notation of its condition. Transfer the silica gel from the fourth impinger
to its original container and seal. The tester may use a funnel to pour the
silica gel and a rubber policeman to remove the silica gel from the impinger.
It is not necessary to remove the small amount of dust particles that may
adhere to the impinger wall and are difficult to remove. Since the gain in
weight is to be used for moisture calculations, do not use any water or other
liquids to transfer the silica gel. If a balance is available in the field,
the tester may follow the analytical procedure for Container No. 3 in 5-10.2.
5.9 Sample Preparation For Analysis. The entire aqueous sample is
concentrated to a nominal volume of 25 ml. The specific procedures follow.
Note the liquid levels in Containers No. 1 and No. 2 and confirm on the
analytical data form (FigurecT~3 or similar form) whether or not leakage
occurred during transport. If noticeable leakage has occurred, either void
the test run or use methods, subject to the approval of the Administrator, to
correct the final results. Treat the contents of each sample container as
described below:
5-9-1 Container No. 1 (Probe Filter and Impinger Catch). To condense the
sample, place the sample or a portion of the sample, including the Teflon
filter, in a beaker; add approximately 10 mis of concentrated HNO^, cover with
a watch glass, and heat to 105°C in a hood. After the liquid contents are
removed from the container, rinse the sample container with 0.1 N HNO^ and add
C-32
-------
the rinse to the sample. If difficulty is encountered in evaporating the
sample without bumping, a few Teflon™ chips may be added. Condense the sample
to a nominal 25 ml; do not allow it to go to dryness. Transfer the condensed
sample to a clean, tare-weighed storage vial. Rinse the beaker with 4 ml or
less of 1:1 HNO^ and add to the vial. Seal the vial and reweigh. Record the
vial tare weight and final weight on the analytical data form. By assuming a
specific gravity of 1.0, the difference between the tare and final weights (in
g) is used as the sample volume (in ml). This volume is necessary to
calculate the total ug of Cr in the sample after analysis using GFAA or ICAP,
since the results are on a concentration basis. Transfer the samples to the
NAA, GFAA, or ICAP laboratory.
5.9-2 Container No. 2 (Sample Blank). Treat in the same manner as
described in Section 5-9-1 above.
5.9-3 Preparation of Cooling Water Samples. Shake the cooling water
sample container to suspend any settled solids. Immediately pour through a
1.0 um-pore size Teflon filter in a vacuum filtration unit. When filtration
is complete, use some of the filtrate to rinse the sample bottle and filter
this rinse through the same filter. Measure the volume of the filtrate using
a graduated cylinder and record on the analytical data sheet; transfer the
filtrate to a clean sample storage container.
If the impinger samples are to be analyzed by NAA, transfer the Teflon
filter holding the filtered residue to a precleaned screw-type vial suitable
for NAA. If the samples will be analyzed by GFAA or ICAP, place the filter in
a beaker with 5 ml of aqua regia and heat on a hot plate in a hood. Bring to
a low boil for approximately 15 minutes. Transfer the solution to a 100-ml
volumetric flask, rinsing the filter and the beaker well with water. Dilute
to the mark. Take a portion of the solution, transfer it to a 40-ml storage
vial, and submit it to the NAA, GFAA, or ICAP laboratory as appropriate.
5.9-4 Preparation of Performance Audit Sample. Pipette the volume of
audit sample as indicated in the EPA audit instructions into a cleaned storage
vial. The audit sample will be used to assess the accuracy of the analytical
procedures.
5.10 Analysis.
5.10.1 NAA, GFAA, or ICAP Analysis. These three analytical methods have
presently been shown to be satisfactory for analysis of cooling tower chromium
samples. Submit impinger train samples and cooling water residue samples to

the Draft Method - "Determination of Hexavalent Chromium Emissions from

6. Calibration
Maintain a laboratory log of all calibrations.
6.1	Probe Nozzle. Probe nozzles shall be calibrated before their
initial use in the field. Using a micrometer, measure the inside diameter of
the nozzle to the nearest 0.025 mm (0.001 in.). Make three separate
measurements using different diameters each time, and obtain the average of
the measurements. The difference between the high and low numbers shall not
exceed 0.1 mm (0.004 in.). When nozzles become nicked, dented, or corroded,
they shall be reshaped, sharpened, and recalibrated before use. Each nozzle
shall be permanently and uniquely identified.
6.2	Propeller Anemometer. The propeller anemometer assembly shall be
calibrated according to the procedure outlined in Section 4 of Method PA_.
6-3 Metering System. Before its initial use in the field, the metering
system shall be calibrated according to the procedure outlined in APTD-0576.
Instead of physically adjusting the dry gas meter dial readings to correspond
to the wet test meter readings, calibration factors may be used to correct
mathematically the gas meter dial readings to the proper values. Before
calibrating the metering system, it is suggested that a leak-check be
conducted. For metering systems having diaphragm pumps, the normal
leak-check procedure will not detect leakages within the pump. For these
cases the following leak-check procedure is suggested: make a 10-minute
3
calibration run at 0.00057 m /min (0.02 cfm); at the end of the run, take the
difference of the measured wet test meter and dry gas meter volume; divide
the difference by 10, to get the leak rate. The leak rate should not exceed
0.00057 n1 /min (0.02 cfm).
After each field use, the calibration of the metering system shall be
checked by performing three calibration runs at a single, intermediate
orifice setting (based on the previous field test), with the vacuum set at
C-35
-------
the maximum value reached during the test series. To adjust the vacuum, insert
a valve between the wet test meter and inlet of the metering system. Calculate
the average value of the calibration factor. If the calibration has changed by
more than 5 percent, recalibrate the meter over the full range of orifice
settings, as outlined in APTD-0576.
Alternative procedures, e.g., using the orifice meter coefficients, may be
used, subject to the approval of the Administrator.
Note: If the dry gas meter coefficient values obtained before and after a
test series differ by more than 5 percent, the test series shall either be
voided, or calculations for the test series shall be performed using whichever
meter coefficient value (i.e, before or after) gives the lower value of total
sample volume.
6.4	Probe Heater Calibration. The probe heating system shall be calibrated
before its initial use in the field according to the procedure outlined in
APTD-0576. Probes constructed according to APTD-O58I need not be calibrated if
the calibrations curves in APTD-0576 are used.
6.5	Temperature Gauges. Use the procedure in Section 4.2 of Method^ to
calibrate in-stack temperature gauges. Dial thermometers, such as are used for
the dry gas meter and condenser outlet, shall be calibrated against
mercury-in-glass thermometers.
6.6	Leak-Check of Metering System Shown in Figure Cf-1. That portion of
the sampling train from the pump to the orifice meter should be leak-checked
prior to initial use and after each shipment. Leakage after the pump will re-
sult in less volume being recorded than is actually sampled. The following
procedure is suggested (see Figure 5~4 of Method 5): close the main valve on
the meter box. Insert a one-hole rubber stopper with rubber tubing attached
into the orifice exhaust pipe. Disconnect and vent the low side of the orifice
manometer. Close off the low side orifice tap. Pressurize the system to 13 to
18 cm (5 to 7 in.) water column by blowing into the rubber tubing. Pinch off
the tubing, and observe the manometer for one minute. A loss of pressure on the
manometer indicates a leak in the meter box; leaks, if present, must be
corrected.
6.7	Barometer. Calibrate against a mercury barometer as described in
Method pft.
6. Calculations
Carry out calculations, retaining at least one extra decimal figure beyond
that of the acquired data. Round off figures after the final calculation. Other
forms of the equations may be used as long as they give equivalent results.

Instrumentation - ESC used the following instruments to collect data during
test:
;. Sensitive Paper System
Manufacturer: Environmental Systems Corporation
Description: A special filter medium is chemically treated to produce a
distinct color change when wetted. Droplets impinging on
the papers produce blue stains which may be correlated with
droplet size. The system operator records updraft velocity
and selects exposure times which yield serviceable
concentrations of stains. Knowing exposure times and
updraft velocities, analysts studying the papers with
microscopes can calculate droplet size and size
distribution.
2, Air Speed (Upcraft at Exit Plane)
Manufacturer: R. K. 'ioung Company
Model:	27106 Gill Propeller Anemometer
Description; A generator-type anemometer with excellent linearity and
off-axis response. Used to measure fan upcraft velocity to
establish Isokinetic sampling air flow rate. Readout is by
digital voltmeter. In conjunction with this sensor, the
operator measures the air flow direction with a vane-type
sensor to make a correction for off-axis flow, If necessary.

PITOT TUBE MEASUREMENT DROCEDURE
1.	Remove tube and inspect - remove tip protection cap.
2.	With appropriate couplings connected (typically 2" NPT - male), pull rein-
forcing sleeve and "stinger" fully inside coupling and screw coupling snugly
into gate valve (tighten with pipe wrench).
3.	Open valve fully, after making sure once again the stinger is fully
retracted. Witn vaive fully open, pusn pitot tuDe stinger through the rein-
forcing sleeve. Lock into place and purge manometer and lines of all air.
Zero the manometer (i.e., no differential pressure should be indicated, with
total pressure and static pressure ports reading "static" prior to
inserting tube in pipe).
4.	Slowly insert pitot tube into pipe until a deflection is detected. Mark the
tube clearly at the stuffing box. Push tube fully across the pipe until it
contacts the other side. Mark tube clearly again and retract until zero
deflection is seen again. Check this point with previous mark. Measure
distance between marks and add 3/16" to indicated diameter (for offset in
static/total sensing port location). Compare this diameter to the nominal
diameter of the pipe.
5.	Calculate and mark measurement stations. No fewer than 20 stations per
diameter should be used for pipes greater than 36" diameter. Check to see
if manometer is zeroed and initiate traverse. Visual readings of manometer
should be no less than one minute. Periodic checks using 25-50 instan-
taneous manometer readings averaged and compared with the "eyeDall" average
at a single point snould be conducted.
6.	Other perpendicular traverses should be conducted similarly with center-point
readings compared from each traverse for consistency.
7.	Ambient temperature and water temperature should be measured during traverse
to correct manometer balancing fluid and water density, respectively.
8.	Pitot tube tip should De inspected for blockage/damage before and after each
traverse.
9.	Any anomalies or problems, such as vibration, apparent backflow, etc. should
be noted.

Pip* Caliper—See Fig. 1.
This instrument consists oi a brass rod which passes
through an eccentric stuihng-box The lower end is
hook shaped, and to the other end is attached an
index collar and handle.
To attach the caliper, pull the rod all the way up
and screw the stuffang-box on the corporation cock,
making a water-tight joint with the leather washer.
Open the corporation cock and push the rod in
until it touches the pipe. (See Fig. 1.) Turn rod 1 SOc.
Measure the distance between index collar and stufi-
ing-box. Pull rod up until hook just touches the pipe.
Again measure trom stufiing-box to index collar. Tne
inside diameter ol pipe is equal to the diiierence be-
tween these two measurements plus one inch, the
one inch being added tor the length oi the hook
Caution should be taken to push the rod against
the walls of the pipe slowly and gently, since the
pipe may be coated with tubercles and incrustations,
or there may be sand or sediment on the bottom.
Should the rod be pushed too iorceiuliy against the
Dipe. these interior conditions would not be detected.
Remember that it is the actual working diameter oi
pipe, as near as can be determined, that should be
used in How calculations.
SIMPLEX PHOT ROD
Description
The Simplex PFA Pilot Rod illustrated in Fig. 2 is a
pair of tubes in a casing One tube transmits the Rei-
erence pressure received at the side orifaces, and the
other tube transmits the impact pressure received at
the Impact orihee. which taces the flow.
The Simplex Rod is provided with a split clamp
which holds the tube in position and prevents it be-
ing pushed out by the water pressure, a stuihng-box
which can easily be packed with any suitable pack-
ing and a stop collar near the orihee end oi the rod
to limit the withdrawal oi the rod through the stuihng-
box.

sure to remove the protecting cap from the oribce
:nd, then see that the tube is fuliy drawn up so that it
vill escape corporation plug Screw connection nut
m corporation cock, making a warier-tight joint by
the leather washer.
Have all cocks on Pitot Rod closed, and then open
:he corporation. Open the air cocks at top of Pitot
Rod to blow the air out oi tube and aiso out of top of
pipe, should any be lodged there.
Push the Rod in until it touches the pipe, and meas-
ure the distance irom maex collar to traverse scale
flange. Pull the Rod out a distance equal to the radius
of the pipe minus Vi inch and secure the Rod in this
position by tightening the clamp collar, and at the
same time being sure that the arrow on the crown
casting of Rod points in the direction of the flow.
If the direction of the flow is unknown, this can be
determined by the use oi the manometer connected
to the Pitot Rod. Observe the deflection in manometer
when arrow on crown casting points along the pipe
in one direction. Then revolve the Pitot Tube 18D° so
that the arrow points along the pipe in the opposite
direction. The water will be flowing in the direction
that produces the greater deflection of the liquid in
manometer.

Connecting Manometer to Pi tot Rod
Tne manometer may be connected with two lengths
of hose, either directly to the Pitot Rod at CD and (R),
as shown in Fig. A, or it may be connected at (D
and CD at the Recorder (rig. 10) when the latter is
connected to the Pilot nod. Whiie using the mano-
meter thus connected, shut oft the Recorder by closing
cocks (I) and (R) on Recorder. Whenever the mono
meter is being filled with liquid or is blown off ior
expelling possible collections oi ar- ircm it, always
iirst close cocks CD and (R) ct Recorder. Likewise,
whenever air is being blown irom Recorder always
hrst close cocks CD and (R), thus shutting erf the mano-
meter to prevent the danger of blowing the liquid ircm
same. (See Fig. 10.)
Toe Pitot Rod located as described above has its
orihees at the center of the pipe. This it the usual

FILLING MANOMETER WITH LIQUID AND
BLOWING OUT AIR
Remove wmg nut on top of manometer. Lift off top
assembly, exposing holes to glass. Pour liquid, previ-
ously mixed (as explained en Page 6), through a
iunnel into either hole.
It is usually desirable to £11 the sonometer half

LIQUID FOR MANOMETER
When measuring low velocities use a low specific

Specific Gravity Determination
The specific giaviry of the hquid or mixture can be
determined by pouring Eame in a giass cylinder and

liquid gravity is employed, the specific gravity can
easily be determined in tne following manner.
Pour the liquid to be checked into the manometer
and tnen pour some water into one side of the
manometer, which will deflect the liquid. Tnere may
be water in one side only or in both sides of the
manometer, and it is only necessary to have more
water in one side than in the other so as to produce
a aeflecuon of the liquid. In the interest of ciose
accuracy it js advisable to have as large a deflection

mination of the SDeciiic gravity both legs of the
manometer are open to atmosphere, that is, cocks

TRAVERSE STATIONS—See Pig. 4
Wherever o mam is lapped ior the purpose of
measuring the Sow of water, let it be called a station
and named or designated by an assigned number.
When selecting a location ior a station always, if
possible, select a point m the pipe line where there
is a considerable length oi straight pipe iine, where
the flow will be undisturbed by valves, tees, or bends.
Tap the pipe at the selected location ior a one-inch
corporation cock. Tne tap is usually made on the top
of the pipe. It may, however, be made at the side oi
the pipe or at any other point on the circumference
It is desirable that the pipe be not tapped so deep
that the corporation cock will extend through pipes
and project beyond the inside suriace of the wall oi
the pipe.
When it is impossible to make tap in a long straight
length of pipe, say where the nearest up-stream
valve, tee, or bend is less than 20 or 3D diameters
from the station, then two taps about 90° apart with .
one about 4" to 6" ahead oi the other should be
tapped in the pipe.
For steel pipes first attach a strep service clamp

An accurate record should always be made and
kept on file giving the location of all stations and the
distance of same from at least two fixed landmarks.
PIPE TRAVERSE—Sue Rgi. 4, 6, 7
Tne object of making the pipe traverse by the use
of the Pitot Rod and the manometer is to ascertain
the relation between the mean velocity and the cen-
ter velocity in the pipe. The Pitot Tube measures
velocity only at the point m the pipe where the ori-
iices are located. Ii the oribces of the Pitot Tube be
moved along the diameter oi the pipe it will be
noticed that the velocities are diiierent ior different
locations of the oriiices, and that they gradually in-
crease as we approach the center of the pipe. Tnere-
iore, to accurately determine the quantity of water
flowing it is necessary to know the traverse coeffi-
cient, C = V«/V«, that is the relation of the mean
velocity to the center velocity.
Tne method to be employed in making the traverse
is that of dividing the pipe into imaginary rings or
annuli having equal areas, and then taring readings
oi the defections oi the liquid in the manometer when
the oriiices of the Pitot Tube are placed at a point i
each nng such that a circle through that point wi
divide the nng into two equal areas.
This is illustrated in Fig. 4. Refer to the right-har
lower corner where circular cross-section of c pi;
is shown. Here the pipe is divided into five rings
equal area. R) is the radius to the orifice locatic
ior the hrst nng. Ry is the radius to the oniice locatit
ior the second ring. Rt is the radius to the circw
ierence oi nng (a). Tne area of nng (a) equals the
area oi nng (bl. Tne rings (a), (b), (c), (d). (e),
(f), (g), (hi, (i) and (j) have equal areas and the
area of any one of these is equal to half the area of
any one oi rings, 1, 2, 3, 4, or i.

culated by ioimula CIS) page 13 or they may be

Dear Bill:
I would like to expand on the results I gave you on the phone
concerning your tests at Paducah. As I understand it, your team ran the
paired trains that we recommended, one train being a conventional isokineti
impinger train and the other an impinger train sampling from a tube with a
disk-shaped collar positioned at 90 degrees from the direction of gas flow.
Our best estimate on the collection behavior of this train comes from the
theory of Zebel (In Recent Developments in Aerosol Science, Edited by David
T. Shaw, Wiley, NY, 1978). The only experimental data we know of was for a
geometry with a slightly different collar by Liu and Pui (Aerosol Sampling
Inlets and Inhalable Particles, Atmospheric Environment, J_5, 589-600, 1981)
According to Zebel*s paper, the collection efficiency of drops by tne disk
train should be given by the equation below:
pff = 	!	
1 + 1.09 STK
where
STK = V PCD2 /9ud
and	V	=	gas stream velocity (cm/sec)
P	=	droplet density (1 gm/cir,3 in this case)
C	= Cunningham correction factor (= 1 for this size)
D	=	droplet diameter (cm)
p	=	gas viscosity (about 180 x 10~° poise)
d	= sampling cube inner diameter (cm)
Although their geometry is slightly different from our setup, the
equation fits the data of Liu and Pui fairly well when the correct tube
diameter is assumed (see Figure 1). Table 1 contains calculated D^g values

for the four "90° train" runs. Note that while the calculated D5Q is on the
order of 13-16 urn, tne efficiency curves are broad, and significant
collection occurs at higner droplet sizes. Tne calculated collection
efficiencies for the velocities encountered by the "90° trains" at Paducah
are plotted in Figure 2. I have also done a convolution (see Table II) of
the calculated collection efficiency of the 90° train witn one of the size
distributions reported oy ESC. If their size distributions are good in the
smaller size range, the 90° trains should collect less than 10 percent of
the drift mass. I do have some questions about their technique, though,
which I will discuss below.
Although you did not directly ask us to analyze the ESC technique, I
felt a word about it was in order. The most definitive experimental work of
which we are aware is that of May and Clifford (The Impaction of Aerosol
Particles on Cylinders, Spheres, Ribbons and Discs, Ann. Occup. Hyg. 10,
83-95, 1967), which gives efficiency curves for the disk oody impactor such
as those used for our study. I have enclosed a copy of their results (their
Figure 7) which illustrates it. In their plot the parameter P=\/Z is given
by half the value of STK in equation 2 (where d now is the paper disk
diameter). Thus P is proportional to the square of the droplet diameter D.
Using this data the disk Djq value expected for the velocity range covered
can be calculated and are included in Table I.
I draw two conclusions from the May and Clifford data. First, it is
probably a decent approximation to assume that the sum of the collection by
the paper disk and the 90° tram will be approximately the same as the
isokinetic nozzle train for all sizes, with the greatest error of
approximation occurring for particles about 20 ura. The efficiency curves
for a disk impactor and those of the 90° sampling tram are fairly "sloppy"
in terms of particle size separation. The paper disk collects large
droplets, and tne 90° train collects the smallest droplets, with near unit
efficiency. Thus both significant ends of the size spectrum are collected
well.
A second point I should emphasize is that the sensitive paper results
are subject to some question below about 25-50 ym. While presumably ESC can
distinguish spots corresponding to 10-20 um size droplets, they may
underestimate the actual flux of these drops. The Ranz and Wong (IMpaction
of Dust and Smoke Particles, Industial and Engineering Chemistry, 44,
1371-81, 1952) collection efficiency used by ESC to establish correction
factors does not seem to be fitted by the experimental data seen on Figure 7
of May and Clifford.

The relative contribution of droplets in the 10-50 um size range may
not be significant for the low efficiency drift eliminators in this study.
However, the sensitive paper may significantly underestimate the small
droplet flux downstream of higher efficiency collectors or in any duct where
a condensation droplet mode exists.
Please let me know if I can be of further help.

CALIBRATIONS
All measuring equipment Entropy uses is initially calibrated before use.
Equipment which can change calibration is both checked upon return from each
field use and is also periodically recalibrated in full. When an instrument
is found out of calibration, it is so noted in the report and appropriate
adjustments are made to the final results. The equipment is then repaired and
recalibrated or retired as needed. Specific equipment is handled as follows:
Propeller Anemometer - All propeller anemometers were calibrated
and/or checked using the procedures in the draft test method for the
use of the propeller anemometer. This included a full calibration in
the wind tunnel at 10 increments of flow alignment angles from -90
to +90 . The electrical system was checked with a constant rpm motor
to ensure proper outputs. The bearing torque on the anemometer shaft
was checked with a bearing torque check device. All propeller
anemometers used in this program meet the requirements as specified by
the EPA draft method.
Dry Gas Meter and Orifice Meter - All Entropy meter boxes are
calibrated upon purchase and at least once every six months against a
secondary test meter (one calibrated against a wet test meter)
according to their usage history. Basic procedures are outlined in
the EPA Publication No. APTD-057&- The only differences are in the
choice of flow rates used and the volumes metered at each flow rate.
After each field use, quick checks are performed to ensure delta H@
changes of less than 5%- These checks compare the orifice against the
dry gas meter. If greater than 5% changes occur, recalibration and
repair are instituted.
Nozzles - Each nozzle is calibrated upon purchase, and thereafter
whenever it becomes apparent that the nozzle has become damaged. Each
nozzle is inspected upon return to laboratory from each field use.
The diameter is measured on five different axes, with the high and low
readings differing by no more than 0.004 inches as a tolerence.
Temperature Measuring Instruments - After each field use, the
thermocouples or thermometers are calibrated against an ASTM precision
mercury-in-glass thermometer across a wide range of temperatures. If
the initial reading is not within + 1.5% of the absolute temperature
reading of the standard thermometer, the instrument is adjusted until
it is in the acceptable range.
Three-Dimensional Pitot Tube - Prior to field use, the 3~D pitot
tube was calibrated in the wind tunnel using the procedures described
in EPA Method 1A. The pitot tube meets all requirements of the
Method.
D-3
-------
Magnehelic Gauges - After each field use, each Magnehelic
Gauge is calibrated against an inclined manometer at three different
settings (low, medium, high) over the range of the individual gauges.
If the readings differ more than +_ 52 from the manometer readings, the
Magnehelics are recalibrated.
Barometer - After each field use, each barometer is checked
against a mercury barometer.

jpirtl-rivtted pip* lina (tuba lengths ara tpproximata). The
in* has a 30-foot test taction of 24-inch seamless steal pipe
¦4hose thickness is 3/B inches and whose internal diameter at the
:raverse location is 1.937B -ft (based Dn a series of eight
nternal diametral measurements at the traverse location). Water
ias pumped through the pipe line by means of a 20 x 20-in.
zentrifugal pump driven by a 200 HP synchronous motor running at
^00 rpm.
'he actual flow rate was obtained volumetrical1y by timing the
iai of a float gage in a tank which had a uniform area of 199.7
q . f t. The el apsed time was Indicated by means Df a digital
-.top watch reading to 0.01 sec. Rise distances of B to 9 ft were
employed. Horizontal and vertical traverses were taken at a test
•tation some 97 ft downstream from a long radius bend with rough
:urning vanes and some 14 ft upstream from another bend. Two
i«ts of traverse ports are available* for normal length tubes,
ruely vertical and horizontal traverses can be made; for tubes
if extended length, the "vertical" port is 20 degrees off from
:rue vertical *~ as to allow the tube to extend into a 5—ft deep
rhannel while the "horizontal" port is 100 degrees from true
vertical so as to allow the tube to clear other laboratory
jipes. The former ports were used in these calibrations. Each
irivirie consisted of velocity readings at 17 points. The Pitot
:ube positions tabulated and used in plotting the accompanying
iraphs are based on the distance of the impact hole Df the Pitot
:rom the pipe wall on the far side of the pipe from the
attachment device. Pressure differentials were obtained with a
iifferenti*l pot—type manometer using carbon tetrachloride as
:he gage fluid; these observations were read in feet, tenths,
:nd hundreths. In obtaining manometer differentials, it was
leceisary to average the fluctuations over a period of time
(usually a minute or so).
The calibration coefficients have been evaluated both in terms
3f a pipe velocity based on the actual pipe area and on an area
:srr:ctEil fur the blockage effects of the Pitot tube. The area
3f the pipe at the test section was evaluated to be 2.9493
jq.ft. The area of the Pitot tube exposed to the flow when
nserted to each reference position was calculated (see attached
blockage calculation sheet). The average of these areas (0.0301
'q.ft. for PFA 233B) has been taken as the blockage area. The
!et area of the pipe for this Simplex was, therefore, Anet ¦=
2.9493 — 0.0301 ¦ 2.9192 sq.ft. The net pipe velocity would be
-he total flow rate as measured volumetrical1y divided by this

The g«9» rtiding*, th« vtlocititi calculated therefrom, and
ther ptrtintnt information from the test run* art tabulated on
ha accompanying data sheets and computar printouts. Th* avcragi
indicated velocity -from the Pitot tube was calculated by
Iveraging the fourteen velocities determined at the mid—areas of
qual-area annuli (values at traverse locations 1, 9, and 17,
ot at mid-areas, were excluded). These experimental points were
plotted and a smooth curve was drawn through them. These curves
ppear in the accompanying figures. Where any of the
xperimental points deviated substantially from this smooth
curve (usually where there is evidence of vibration), a velocity
alue from the smooth curve was substituted for the indicated
elocity. These values are also listed on the data (computer)
heets as adjusted velocities.
he procedure for averaging the velocity values at equal area
nnuli is in accord with an accepted procedure (cf, the ABME
report o-f Fluid Meters). The procedure for substituting curve
alues for indicated values is based on the following line of
•asoningt Manometer readings, at locations where tube vibration
or other flow abnormalities occur, can and do vary considerably
2rom normal values. When the tube is vibrating, the manometer
ladings usually increase. Inclusion of these higher values in
_.tb coefficient calculations reduces the tube coefficient below
that which would obtain without the vibration. Since vibration
f the tube depends on many factors (tube extension, flow
¦locity, packing stiffness, mass and elastic characteristics of
the rod, flow fluctuation severity, etc.) and since in field use
lese factors could well come together differently than in the
ilibratio-n runs, it is felt that such readings should be
replaced with values taken from the smooth curve through the
(oints free Df vibration or other abnormalities. From many,
any previous calibration runs using this test station, the
eneral shapes of the velocity profiles, modified by Pitot tube
blockage, are well known. Accordingly, the smooth curves (drawn
tnoring "contaminated" values) can be produced with quite a
gh degree of confidence. At the same time, it must be stated
that not all velocity determinations suspected on the basis of
tactile and/or audible signals of being influenced by vibration
Mirn out to deviate significantly from the smooth curve drawn
xnrough the mean Df the points. Contrariwise, when there is no
tactile or audible evidence, it is not assured that the tube is
¦bration free and the velocity points might register higher
wan normal on the'velDcity profile. In the case of the present
tests, tactile and audible evidence of vibration did appear at
»ny of the traverse positions when testing these unreinforced
«>plp*e5. In fact, for Tube 6A, when the tube was extended
towards the opposite wall, the vibrations became quite violent.
I net adjusted coefficient has been calculated using the
"Justed traverse velocities and the average pipe velocity based
on the pipe area corrected for Pitot tube blockage. This
tlibration coefficient is calculated by dividing the net pipe
l°city determined volumetrical1y (10.3461 fps for the example
shown above) by the average adjusted Pitot tube velocity as
rllows: C ¦ 10.3461/12.4165 ¦ 0.B333 (horizontal high velocity
-------
-cvrrt> •for PFA 233B (WF6). In the writtr '« view, a cotffici»nt
«sed on adjusted Pltot valocitiif and a pip* velocity corr«cttd
jr blockage must be used for interpreting natsuriniinti made in
i pes of other ilz>t. The -following tabic »ummame direction. The direction Df traverse, whether vertical or
horizontal, did not seem to be a crucial factor in the
-ali brati ons.
Recently, a calibration test of a reinforced Simplex gave a
rather clear indication as to a possible reason why some tubes
give higher coefficients. At the request Df a client who was
suaei vir»y tint calibrations and to eliminate the' necessity of
aoving -the Simplex rod inside the reinforcing tube, a long IB to
20 in. nipple was put between the valve and the Pitot. This
nipple was some ordinary schedule pipe found in the laboratory.
During the course of the calibrations, when the Pitot was taken
in and out of the test pipe, the forces of tightening the nipple
caused the nipple to distort. By the end of the calibration the
nipple was quite bent and showed it. When the results were
analyzed, it was found that the coefficient increased gradually
and consistently as time Df day progressed or as the pipe was
-------
becoming mori and mori distorted. Whin we rattitid the umi tube
i -ing * h«»vy achidulc nipple of the umi length, thi
, iibr«tlon Hit right at the ivirtgi of many taiti. To be aura,
same situation did not obtain in these prvitnt calibrations
with ragard to a long nippla. However , the lami type of result
i uld be obtained with a standard unrei nf Dreed Simplex if its
, id was bent so that it did not traverse directly across the
pipe on a diameter but went off on some chord o-f the
