                            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.

                           SECTION IV

                   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.
                               44

-------
  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.
