SECTION I
INTRODUCTION
Under the Clean Air Act of 1970, the Environmental Protection
Agency is given the responsibility of establishing performance
standards for new installations or modifications to existing in-
stallations in stationary source categories. As a contractor,
Monsanto Research Corporation (MRC), under the Environmental Pro-
tection Agency's (EPA) "Field Sampling of Atmospheric Emissions"
program, was asked to provide emission data from the Anaconda
Copper Smelter at Anaconda, Montana.
The field test work was directed by Robert M. Martin, Field Test-
ing Section, Emission Measurement Branch, EPA. The sampling was
performed by Monsanto Research Corporation with Darrell L. Harris
as team leader.
This report tabulates the data that were collected from the ef-
fluent of the converter line, the electric furnace, and the fluid
bed roaster of the Anaconda smelter. Any portion of these waste
gases up to approximately 300,000 cubic feet per minute can be
directed from an old flue into two separate ducts, passed
through a system of cooling spray chambers, and then directed
through three fans to a multi-chamber baghouse. The baghouse
effluent is then directed by a new flue to the base of the main
stack and vented to the atmosphere. Any portion that is not
directed to the control device is bypassed through the old flue
to the main stack.
-------
Sampling was performed on both the inlet and outlet of the spray
chambers/baghouse control device. Both sites were measured for
particulate concentrations according to procedures described in
the Federal Register, Method 5, "Determination of Particulate
Emissions from Stationary Sources". Method 1, "Sample and Veloc-
ity Traverses for Stationary Sources"; Method 2, "Determination
of Stack Gas Velocity and Volumetric Flow Rate (Type S pitot
tube)"; and Method 3, "Gas Analysis for Carbon Dioxide, Excess
Air, and Dry Molecular Weight" are other procedures that were
carried out. Both locations were also measured for arsenic con-
centrations. This procedure utilized a modified Method 5 partic-
ulate train designed with additional impingers and various
impinger solutions to remove arsenic. Particle size determina-
tions were made at both inlet ducts using a Brink® cascade im-
«pactor. Particle size determinations were made at the outlet
using an Andersen cascade impactor.
:No modifications were necessary to prepare the ducts for sampling.
.Sampling at both inlet ducts was conducted through four existing
ports on each rectangular duct. Sampling on the outlet of the
baghouse was performed utilizing the existing ports on the circu-
lar flue at the base of the main stack.
The following sections of this report include: (1) summary of
results, (2) description of the process, (3) location of sampling
points and traverse data, (4) sampling and analytical procedures.
Appendices include all field data from this sampling project.

SECTION II
SUMMARY OF RESULTS
The two sampling locations at this plant, shown in Figure 1, are
designated as A for the inlet and B for the outlet. Since there
are two inlet ducts, the west duct is designated as 1A, and the
east duct as 2A. At each location there are runs numbered 1
through 6. Runs 1, 2 and 3 at each location were conducted for
the purpose of determining the arsenic concentration, and runs 4,
5 and 6 were for the purpose of determining the total particulate
concentration.
Tables 1 and 2 show a summary of the arsenic concentrations
found in the west inlet duct, and Tables 3 and 4 show the arsenic
concentrations found in the east inlet duct. Tables 5 and 6
show the arsenic concentrations found at the outlet duct.
Tables 7 and 8 show the total particulate mass measured at the
west inlet duct, Tables 9 and 10 show similar results for the
east inlet duct. Tables 11 and 12 show the total particulate
emissions at the outlet. Tables 13 through 21 show the particle
size determinations made at both inlets and Tables 22 through 28
show the particle size determinations made at the outlet. Ar-
senic analysis results for process samples collected during the
sampling period are in Table 29.

LOCATION OF SAMPLING POINTS
INLET TO CONTROL DEVICE
The inlet to the control device consists of two ducts originating
from the same point in the old flue and continuing in a V shape
in individual ducts to the spray chamber building. Both ducts
run horizontally for approximately 20 feet and then bend slightly
downward at about a 20° angle and continue this direction until
joining the spray chamber building. The ducts are rectangular
for the vertical sections and are each 11 ft. tall by 8 ft. wide.
After the downward bend, the ducts form a slight transition un-
til they empty into the spray chamber at slightly larger height
dimensions but the same width dimensions. The sampling ports are
located just upstream of the downward bend. Approximately 6 feet
upstream of the port locations is a damper on each duct that can
be closed to bypass the control system. There are four ports on
each duct in a vertical line allowing four separate individual
traverses of each duct. A sketch of the top and side views of
this location is shown in Figure 2. Traversing at these loca-
tions used four traverse points per port, however, sampling of
the bottom port on each duct was not performed due to the dis-
covery that an accumulation of material was blocking the first
and fourth traverse point.

OUTLET OF CONTROL DEVICE
The gases from the baghouse are vented through an eleven foot
diameter fiberglass flue. This flue exits at the top of the bag-
house building, makes a right hand turn at approximately 45°
angle, and continues up the hill at various angles until an ap-
proximate horizontal position has been reached. The duct then
runs through a large sampling building. The ports, 4 inch
flanged pipe, are located on each side and the top of this duct
inside the sampling building. There are three such ports on each
side and a single port at the top. Sampling was performed
through the south side horizontal port and the single vertical
port on top. Eight traverse points per port were sampled giving
a total traverse of 16 points.
The nearest disturbance upstream from the port location consisted
of a bend from slightly uphill to horizontal and was approximate-
ly 88 feet from the ports. The nearest disturbance downstream
from the ports was a bend from horizontal to slightly upward and
was approximately 54 feet from the ports. A sketch of this lo-
, cation is shown in Figure 3.
It was discovered after several runs had occurred that a distur-
bance existed approximately 2 feet upstream of the horizontal
sampling port. This disturbance consisted of a single 1 inch
pipe traversing horizontally the entire diameter of the duct and
was used by the plant as a velocity measuring device. The effect
that this device may have on sampling was discussed at this time
and it was decided that a disturbance of this small magnitude
would have very little effect on isokinetic sampling of particu-
late. It was noticed that the flow indications from the pitot
tube readings were extremely constant.

SAMPLING AND ANALYTICAL PROCEDURES
SAMPLING PROCEDURES
Particulate Sampling - Inlet
The inlets to the control device were sampled generally in ac-
cordance with the Federal Register methods. Some exceptions to
the methods are listed below.
1. This location did not meet the minimum accepted criteria
for upstream and downstream distances to disturbances, even
if the maximum amount of sampling points had been used.
Since this was an inlet, and data from these points are to
be used only for the purpose 'Of determining control device
efficiency, a sixteen point traverse was selected. Four
traverse points per existing port were laid out. Unfortu-
nately, the lowest port at each location was discovered to
have an accumulation of material in the duct at two of the
four traverse points, point 1 and point 4. Since the probe
would have to be passed through this accumulation of materi-
al to sample the center 2 points it was decided to eliminate
this traverse entirely. These ducts were therefore sampled
using a 12 point traverse each.
2. Integrated gas samples for dry molecular weight were col-
lected in the conventional manner in a Tedlar bag. However,
41
-------
analysis 'of the gas was performed using the Fyrite technique
rather than Orsat. This was determined to be sufficient
since no CO was expected to be present in the gas and the
molecular weight of CO is the same as that of nitrogen. Con-
sequently, only oxygen and carbon dioxide were determined and
the rest of the gas was assumed to be the molecular weight of
nitrogen. S02 was known to be present at 3%, however, it was
ignored for the purpose of calculation of dry gas molecular
weight.
3. The Method 5 particulate train was modified by the use of an
8 foot stainless steel lined probe, and a 10 foot Teflon
lined heated flexible probe line connecting the probe to the
filter in the oven. These devices were necesary due to the
confined configuration of the sampling location.
Particulate Sampling - Outlet
The outlet of the baghouse was sampled following the Federal
Register methods more rigorously. The only two exceptions to
the Federal Register methods was the use of an 11 foot long
stainless steel lined probe and 10 foot long flexible Teflon
lined heated probe line (as was used at the inlet) and the use
of the Fyrite technique for dry gas molecular weight determina-
tion. All other techniques used followed the Federal Register
methods. Again, S02 was ignored in calculating dry molecular
weight.
Arsenic Sampling - Inlet and Outlet
The arsenic train used at all locations was a modification of
Method 5 particulate sampling system. It consisted of a stain-
less steel lined heated probe, a Teflon lined heated flexible
probe line, a heated cyclone and filter, 3 modified
42
-------
Smith-Greenburg impingers each containing 100 ml of 10% H202 so-
lution, a standard Smith-Greenburg impinger with 100 ml of 0.1 N
NaOH solution, an additional 3 inch Method 5 type filter, another
standard Smith-Greenburg impinger with 100 ml of 0.1 N NaOH solu-
tion and a final modified Smith-Greenburg impinger containing
200 grams of silica gel. The probe, flex line, cyclone and fil-
ter were all operated above the dew point of the stack gas and
generally above 225°F (107°C). The impingers were all kept in a
water/ice bath.
Cleanup of this train entailed several sections and generally
resulted in obtaining six separate fractions from the train.
These fractions are listed below:
F-l - filter and collected particulate.
F-2 - probe, cyclone and front half filter holder
washings, rinsed once with distilled water
and once with 0.1 N NaOH. The probe and flex
line was rinsed twice with distilled water
and brushed, and twice with 0.1 N NaOH and
brushed.
F-3 - contents of first three impingers. A dis-
tilled water rinse, and a 0.1 N NaOH rinse
of the first three impingers.
F-4 - the contents of the fourth impinger. A
distilled water rinse, and an 0.1 N NaOH
rinse of this impinger. Also, the front
half of the secondary filter holder was
washed with distilled water and 0.1 N NaOH
into this container.
43
-------
F-5 - the secondary filter located between the 4th
and 5th impinger.
F-6 - the contents of the fifth impinger and distilled
water and 0.1 N NaOH rinsing of this impinger,
and the back half wash of the secondary filter
holder with distilled water and 0.1 N NaOH.
The entire train prior to assembly was rinsed thoroughly with
distilled water and the distilled water discarded. The silica
gel was removed from the final impinger, its weight determined
and the silica gel discarded.
,CALCULATIONS
' The standard EPA Method 5 computer program used at MRC has no
i provision for calculation when a gaseous material other than
V.water is removed in the,impinger train. When a material such as
*S02 exists in the gas stream at the concentrations encountered
in this project, and its removal is not accounted for, a sizeable
error is introduced. To reduce the effect of this error, the
amount of S02 that was in the stack gases was added to the mea-
sured meter volume. In this case, the meter volume was increased
by 3% as if the S02 had not been removed. The following calcu-
lation was used to compute an assumed meter volume for arsenic
runs:
= assumed meter volume
Since H202 (which removes S02 from the gas stream) was used for
arsenic trains only, this calculation did not apply to particu-
late runs.

PARTICLE SIZING
The particle sizing runs performed at the inlet to the control
device were done using a Brink® BMS-11 sampler. The sampler was
operated according to the accompanying manual.
Sampling was conducted at various points in both ducts. The
points sampled were selected because of their convenience and be-
cause the velocity at these points was similar to the average
velocity of the duct. The flow rate through the sampler was de-
termined with the use of the preliminary velocity traverse data
and the various calibration curves provided with the instrument.
The velocity at the sampling point was determined and the re-
uired probe tip nozzle selected to match the velocity and, stay
within the volumetric flow rate requirements of the impactor
while maintaining isokinetic conditions at the sampling point.
With the flow rate determined, the required pressure drop across
<. the impactor was selected from the calibration curve. This pres-
sure drop valve was then corrected for actual temperature and
•'- pressure conditions. The probe tip was placed at the sampling
'. point and the run conducted.
The pressure drop across the particle sizer resulted in a calcu-
lated flow rate through the impactor and, therefore, the desired
particle size distribution could be calculated from mass data of
each stage. The mass collected on each stage was determined us-
ing a Kahn electro-balance in the field.
The impactor train consisted of a probe tip, a 48 inch stainless
steel probe, a cyclone, the impactor, a final packed bed filter,
a water knockout flask, and finally a vacuum pump.
A total of ten particle sizing runs were attempted with number 3
being discarded due to pulling water into the impactor during
45
-------
pressure check. Each run was conducted for 15 or 20 seconds,
depending on conditions.
The particle size at the outlet was determined using the Ander-
sen impactor.
The Andersen particle sizing was conducted in the 11 foot diame-
ter duct leading from the baghouse and spray chamber to the stack
(outlet monitoring site "B"). The sampling train used consisted
of the following equipment listed in order of the flow: a 7 mm
diameter probe tip; a curved (90°) probe tip to Andersen head
connector; standard Andersen heads; a 4 foot stainless steel
probe; an equivalent condenser; a Smith-Greenburg impinger
charged with color indicating silica gel; and an EPA-5 console
equipped with a dry gas meter, digital electronic thermometer
and an inclined manometer. Also, an S-type pitot tube was con-
nected to the probe so the stack gas velocity could be continual-
^ly monitored.
A total of 8 particle sizing runs were made with one being dis-
carded due to velocity variations in the Andersen head. Each
run was conducted for 45 minutes under isokinetic conditions.
The runs were made with the probe assembly inserted 32 inches
into the outlet duct at an angle of approximately 30° below the
horizontal. This was due to the presence of a one inch diameter
pipe which traversed the duct horizontally about 15 feet up-
stream of the sampling port.
At the completion of each run, the moisture collected was mea-
sured and the Andersen heads were opened and desiccated for 24
hours. After desiccation, each stage was weighed, then the
filter was removed and the stage assemblies were cleaned, desic-
cated and reweighed to provide partial tare weights. The tare
weights of the filters were taken during the assembly of the
heads (after desiccation for 24 hours).
46
-------
All weight measurements were made with a Mettler analytical
balance. The balance was calibrated daily and rezeroed before
each weight determination.
Calculations were performed using the method and tables provided
in the Andersen manual.
ANALYTICAL PROCEDURES
Particulate
Analysis of particulate samples were performed using the method
outlined in the Federal Register/ Method 5 "Determination of
Particulate Emissions for Stationary Sources". This method pro-
vides for determination of the mass of particulate matter col-
lected in the probe, cyclone, and filter system of the Method 5
train. It does not, however, provide for determination of con-
densable particulate collected in the impinger section of the
train. These loadings were determined using the methods outlined
1 in "Specifications for Incinerator Testing at Federal Facilities"
PHS, NCAPC. 1967.
Arsenic
\
Arsenic analysis was performed by separating the liquid portion
of the fractions from the solid portion and performing Atomic
Adsorption Spectroscopy (AAS) Analysis directly on the dissolved
arsenic in the liquid phases. The remaining solid fractions
were digested and also analyzed by AAS. A complete description
of the analytical procedures is presented in Appendix G.
