1.0  INTRODUCTION
York Research Corporation (YRC)  under contract #68-02-2819
was requested by the United States' Environmental Protection
Agency (USEPA)  to perform an emission test program at a
Sodium Carbonate manufacturing plant.  The test program was
conducted at the F.M.C.  Corporation plant, located in Green
River, Wyoming.  Sampling was performed from May 14,  1979  to
May 19, 1979.

The sampling locations included:
     •  Mono-5 Inlet
     e  Mono-5 Outlet
     •  NS-6 Dryer Inlet
     •  NS-6 Dryer Outlet
     •  NS-3 Calciner Inlet
     •  NS-3 Calciner Outlet
                   t
Figures 1-1 to 1-3 show the sampling locations in the process
Samples were collected for solid particulate,  organics and
particle size distribution at each test location.  The objec-
tive of the test program was to determine the emission levels
of controlled sodium carbonate industry.

2.0  SUMMARY AND DISCUSSION OF TEST RESULTS
Tables 2-1 through 2-18 and Figures 2-1 through 2-10 summarize
the results of the emission test program.  These tables present
the results of tests for the following parameters:
     •  Particulate
     e  Particle Size Distribution
     •  Visible Emissions
     o  Organics

Sample analysis for all parameters were performed at YRC lab-
oratories in Stamford,  Connecticut or Denver, Colorado with
the exception of organics.  A portable gas chromatograph with
a flame ionization detector was set up at the test site for
analysis of organic samples.  The particulate concentration
at each of the three inlet test locations were extremely high.
This contributed to nozzle, filter, probe and pitot tube plug-
ging.   All pitot readings were taken after each line was purged
with air.

The following table details the isokinetic ratio results of the
particulate tests conducted at each location.

Several inlet tests failed to meet the isokinetic requirement
(100±10%)  of the reference method.

Anisokinetic conditions can fall into two categories:
     e  The velocity in the nozzle greater than the velocity
        in the stack (V  > V )
                       n    s
     •  The velocity in the nozzle less than the velocity
        in the stack (V  < V )
                       n    s

In the case of V  > V  the measured concentration of particu-.
late is less than the actual concentration in the stack gas.
This is due to the inertial properties of the larger particles -
they tend to pass the nozzle while the gas and the smaller par-
ticles are drawn into the nozzle.  As a result, fewer particles
are collected per unit volume.   Conversely,  in the case of
V  < V  the measured concentration of particulate is greater
 11    «D
than the actual concentration in the stack gas.  This is again
due to the inertial properties of the smaller particles - they
tend to pass the nozzle while the larger particles are drawn
into the nozzle.  As a result,  more particles are collected per
unit volume.  This being the case, it is important to sample
isokinetically in streams, where there are predominantly large
particle.

Correction factors for. anisokinetic sampling are shown in Exhibit
A.  The following tables detail the test results corrected for
anisokinetic sampling.

                        Errors due to Anisokinetic Sampling
  Failure to withdraw a  sample from a flow-
ing stream  at the same velocity as that which
exists locally in the stream will result in  non-
representative sampling.  If the sampling  rate
is much higher than the local stream velocity.
a greater fraction of smaller rather than larger
panicles will be drawn into the probe. If sam-
pling is much lower than the stream velocity,
large particles will be impacted into the col-
lecting probe.
  Although theoretical and experimental  data
are available, a comprehensive study of these
errors has not been made. The data is almost
entirely empirical  and reflects  different tech-
niques using different particles. The influence
of probe shape and size has yet to be fully eval-
uated.
  In Table Cl the errors  due to anisokinetic
sampling rates are given, which represent data
composited  from  several  workers' experi-
ments.*
  Particles used in the studies  yielding  the
data shown were coal dust, dibutyl phthalate,
and fungus spores, all of which are relatively
low density materials, ranging  from 1.3  for
coal dust to about  1 or somewhat less for the
spores. Since particle density will materially
increase the inertial effects, the sampling error
could be considerably larger than the tabled
values for a given particle size. The last column

of the table shows the limit of the concentra-
tion ratio for very- large or der.se  panicles. If
the sampling probe inlet  velocity i« only 50
percent of the  duct velocity and all large (or
dense!  panicles in  the projected  area  of  the
probe inlet are impacted into the probe, twice
as many will be collected as should have been.
Similarly,  should the  sampling  probe inlet
velocity  be twice the duct velocity  and  the
panicle inertia be such that only those parti-
cles approaching in the projected area  of the
probe are  collected,  then  the observed con-
centration  would be one-half  the actual con-
centration.
  It must be remembered  that particles gen-
erated by most natural processes vary widely
in size, and the sampling error will be the com-
posite effect of all panicle  sizes present.

The correction factor for the inlet concentrations was for
large particles since the Bahco analysis showed approximately
50% of the particles at each location to be greater than 44
microns.

                        -11-
Correcting for anisokinetic sampling increased the scrubber
efficiency for test 3 at Mono-5 by 0.03%, decreased the
scrubber efficiency at NS-6 by an average of 0.033 %,  and
decreased the scrubber efficiency for test 1 at NS-3 by 0.03%.

Particle size tests were performed using an Andersen cascade
impactor at each test location except the NS-6 dryer outlet.
No sample was collected at the NS-6 dryer outlet due to the
high moisture content of the gas stream.  Sufficient sample
was collected at the inlet such that an aliquot from each test
was taken and composited for a sieve and Bahco particle size
analysis.  It is not feasible to conduct a particle size
analysis on any outlet filters because of the small amount of
particulate.   Any scraping of the filter would bias the parti-
cle size by introducing fiberglass material into the sample,
also any extraction of the filter by use of solvents such as
water would dissolve the particulate matter and the subsequent
crystallization would not be representative of actual  test
conditions.

3- 0   SAMPLING  METHODS
      3.1   Test Port  Locations  and Sampling Point Determination
      The  location  of the  test  ports and  sampling points at
      each location was  determined in accordance with  guide-
      lines outlined  in  EPA Method 1 (Sample and Velocity
      Traverses for Stationary  Sources).
      The  sampling ports  at  the Mono-5 Calciner  Inlet are
      located  in  the  ductwork between the calciner outlet  and
      the  cyclone inlet  (Figure 4-1).  The  duct  is 4.03  feet
      by 7.22  feet at this location.  Four  sampling ports  are
      located  on  the  bottom  of the  duct.  Method 1 requires a
      48 point traverse but  due to  the extremely high grain
      loading  which caused several  filter changes and plugging
      of the nozzle,  24 points were sampled at two minutes each,
      resulting in a  total test time of  48  minutes.

      The  sampling ports  at  the Mono-5 Calciner  Outlet are lo-
      cated in the stack  which vents the exhaust gases from
      the  scrubber to the atmosphere.  Two  sample ports  are in-
      stalled  90  apart.  'The stack diameter is  60 inches  at this
      location (Figure 4-2)  and 12  traverse points were  sampled at
      5 minutes each  resulting in a total test time of 60  minutes.

      Sampling ports  at the  NS-6 Dryer Cyclone Inlet are located
      in the ductwork between the dryer  outlet and the cyclone
      inlet.   The duct dimensions are 9.104 feet by 4.76 feet
      (Figure  4-3).   Six  sampling ports  are located in the bottom
      of the duct.  Originally, all six  ports were to be sampled,
      but  due  to  obstructions inside.one duct and obstructions
      by permanent scaffolding, only four ports  could be utilized.
      Again, because  of the  extremely high  grain loading,  24
      points were sampled at two minutes each resulting  in a
      total test  time of  48  minutes.

The sampling ports at the NS-6 Dryer Scrubber Outlet
are located in the stack which vents the exhaust gases
from the scrubber to the atmosphere.  The two sampling
ports are installed (90  apart) at which the diameter is
77 inches.  Six traverse points were sampled in each
port for five minutes each resulting in a test time of
60 minutes (Figure 4-4).

The sampling ports at the NS-3 Calciner Cyclone Inlet
are located in the ductwork between the calciner outlet
and the cyclone inlets.   Four sampling ports are located
on the side of the duct.  The dimensions at this location
are 8.032 feet by 8.115  feet.  Thirty sampling points
were used due to the high grain loading and sampled two
minutes each for a total test time of sixty minutes
(Figure 4-5).

The sampling ports of the NS-3 Calciner Dryer Outlet are
located 90  apart in the stack which vents the exhaust
gases from the precipitator to the atmosphere.  The stack
dimensions at this location is 96 inches ID.  Forty-eight
sampling points were used and each point was sampled for
two minutes,  resulting in a test time of ninety-six minutes
(Figure 4-6).

3.2  Gas Velocity
The gas velocity at each location was determined in ac-
cordance with guidelines outlined in EPA Method 2  (Deter-
mination of Stack Gas Velocity and Volumetric Flow Rate).

A precalibrated type "S" pitot tube and thermocouple were
rigidly attached to each sampling probe.  The velocity
pressure was measured on an inclined manometer, and the
temperature on a pyrometer.' Readings were recorded at
each traverse point.

3.3  Gas Composition
The gas composition was determined in accordance with
guidelines outlined in EPA Method 3 (Gas Analysis for
Carbon Dioxide, Oxygen, Excess Air and Dry Molecular
Weight).  Since there is no combustion involved in the
process, the gas composition at each test location was
assumed to be air.  A check was made with a Fy-rite analyzer
for carbon dioxide and oxygen content.

3.4  Particulate
The particulate concentrations were determined in ac-
cordance with guidelines outlined in EPA Method 5 (Deter-
mination of Particulate Emissions from Stationary Sources).

The sampling train consisted of a nozzle, stainless steel
probe,  heated sample box which contained the filter,
impingers, vacuum pump, dry gas meter and calibrated ori-
fice (Figure 4-7) .  The nozzle was rigidly connected to
the probe and the probe consisted of 5/8 inch O.D. tubing
which was wrapped with heater tape to prevent condensation.
Attached to the probe was an "S" type pitot tube and thermo-
couple used for monitoring the velocity pressure and
temperature.  The probe and heater box were attached to
the impinger train by means of a flexible sample line.

The impinger train consisted of five Greenburg-Smith im-
pingers connected in series.  The first impinger was
modified by replacing the impinger tip with a blank stem.
This impinger was initially filled with 100 milliliters of
distilled water.  The second impinger was a standard
Greenburg-Smith impinger containing 100 milliliters of dis-
tilled water.  The third and fourth impingers were identi-
cal to the first and were left dry while the fifth con-
tained 300 grams of indicating type silica gel.

From the fifth impinger the effluent stream flowed
through a check valve, flexible rubber vacuum tubing,
a vacuum gauge, a needle valve, a leakless vacuum pump
and a dry gas meter.

A calibrated orifice completed the train and was used
to measure instantaneous flow rates.  The dual manometer
across the calibrated orifice was an inclined vertical
type graduated in hundreths of an inch of water from
0 to 1.0 inch and in tenths from 1 to 10 inches.

During the test the following data was recorded at each
traverse point:
     o  Traverse point
     »  Sampling time
     •  Clock time
     •  Gas meter reading  (cf)
     •  Velocity pressure  (in. H20)
     •  Orifice pressure drop  (in. H~0)
     o  Stack temperature  ( F)
     »  Dry gas meter temperature - inlet and outlet  (°F)
     •9  Pump vacuum (in. Hg)
     •  Sample box temperature ( F)
     •  Impinger temperature  ( F)

The relationship of AP reading with the AH reading is a
function of the following variables:
     •  Orifice calibration factor
     •  Gas meter temperature
     •  Moisture content of flue gas
     •  Ratio of flue gas pressure to barometric pressure
     •  Stack temperature
     *  Sampling nozzle diameter

A nomograph was used to correlate all the above variables

-------
                     -51-
such that a direct relationship between AP and AH was
determined by the sampler and isokinetic conditions
could be maintained.

At the completion of the test the samples were recovered
in the following manner:
Container #1 - The filter was removed from the filter
               holder and placed in its original con-
               tainer and sealed.
Container #2 - The nozzle, probe, cyclone bypass and
               front half filter holder were rinsed
               with acetone.  The acetone was placed in
               a glass jar and sealed.
Container 13 - The silica gel was returned to its ori-
               ginal container and sealed.

3.5  Organics
A gaseous sample was withdrawn from the source using a
heated, glass lined stainless steel probe.  Samples were
drawn into a prepurged, evacuated, heated (to above the
dew point of the sample gas) 250 ml glass grab flask
until a positive pressure was obtained in the flask.  The
sample was injected into an AID model 621 portable Gas
Chromatograph (GC) directly from the heated grab flask
using the positive pressure obtained while sampling to
fill the sample loop of the G.C.. Two injections per
flask were made to determine the reproducibility of the
sample.

The samples were analyzed for Total Hydrocarbons, 'such as
methane, by using a Ice gas sample loop and a flame ioni-
zation detector.  The column temperature was 125°C.  The
G.C. was standardized employing a range of certified ana-
lyzed methane standards prepared in helium.

3.6  Particle Size Distribution
The particle size distribution samples were collected
using an Andersen Cascade Impactor.  The impactor consists
of multiple stages which collect different particle sizes
(Figure 4-8).   Each stage consists of an orifice of a
specific diameter above a collection plate.  The orifice
sizes of each stage are different and are arranged in des-
cending order, the largest being stage 1.  The sampling
system was set up as shown in Figure 4-9.  The stack con-
ditions were determined and the sample was extracted iso-
kinetically.

As the sample flows through each orifice, and is deflected
off a glass fiber substrate filter placed on the collection
plate, particles of a specific size become impacted on the
substrate while the remaining particles entrained in the
gas stream proceed to the next collection stage.  The range
of particle sizes retained on the substrate varies ac-
cording to the velocity of the gas (as determined by the
sampling rate and orifice diameter), the gas viscosity and
the particle density.  Since the orifices are arranged in
descending diameters, the gas velocity increases and the
particle size collected on each stage decreases.

During the sampling a cyclone preseparator was used to pre-
cut particles above 10 microns and avoid overloading the
collection substrates.  At the completion of each test the
contents of the preseparator and an acetone wash were

     placed in a sample bottle.   The glass  fiber substrate
     filters were returned to their original containers and
     sealed.

     3-7  Visible Emissions
     The visible emissions were  determined  in accordance with
     guidelines outlined in EPA  Method 9  (Visual Determination
     of the Opacity of Emissions from Stationary Sources).

4.0  ANALYTICAL PROCEDURES
     4.1  Particulate
     Each sample from the particulate test  was analyzed in
     the following manner:
     Container #1 - The filter was  removed  from its sealed
                    container and placed  on a tared watch
                    glass.  The  filter and  watch glass  were
                    dessicated with anhydrous CaSO. and
                    weighed to a constant weight.   The  weight
                    was recorded to the nearest 0.01 mg.
     Container #2 - The acetone  washings  were transferred to
                    a tared beaker.  The  acetone was then
                    evaporated at ambient temperature and
                    pressure, dessicated  and weighed to a
                    constant weight.  The weight was recorded
                    to the nearest  0.01 mg
     Container 13 - The silica gel  was weighed to the nearest
                    0.1 gram on  a beam balance.

     4.2  Particle Size Distribution
     The fiberglass substrate filters were  dessicated and
     weighed to a constant weight.   The net weight gain was re-
     corded to the nearest 0.01  mg.

     The acetone rinse of the cyclone preseparator was  trans-
     ferred to a tared beaker.  The beaker  was heated to a

-------
                     -56-
temperature well below the boiling point until the water
was evaporated.  The beaker was then dessicated and
weighed to a constant weight.  The net weight gain was
recorded to the nearest 0.01 mg.

Bahco analysis was also performed on certain locations
due to the high moisture content restricting applicability
of the Andersen Impactor.
