"Based on information developed by Radian Corporation during
Phase I and II studies, the Industrial Studies Branch recommends not to
develop new source performance standards for the potash industry. The
Standards Development Branch concurs with this recommendation."

1.0 INTRODUCTION
Testing to determine participate emissions from a potash plant was
conducted by Scott Environmental Technology, Inc. for the U.S. Environmental
Protection Agency under Contract No. 68-02-2813, Work Assignment No. 37. The
testing was conducted from July 10, 1979 through July 13, 1979 at the
Kerr-McGee Chemical Corporation plant located in Trona, California. The same
equipment was previously tested by Scott for the Environmental Protection
Agency under Work Assignment No. 31 on April 18 and 19, 1979.
Total particulates were measured at the inlet and outlet of control
equipment serving a potassium chloride drier. The control equipment consists
of two cyclones in parallel followed by a venturi scrubber. Total partic-
ulates were also measured at the outlet of a baghouse controlling emissions
from a potassium sulfate drier. Total particulates were determined by EPA
Method #5. The particle size distribution was determined at the cyclone
inlet and scrubber outlet of the potassium chloride drier and the baghouse
outlet of the potassium sulfate drier using an Andersen cascade impactor.
Opacity of the gas emitted to the atmosphere from the scrubber and from the
baghouse was monitored during each test by a smoke reader. Samples of the
potassium chloride and potassium sulfate drier feeds were collected to
determine moisture content.
The test arrangements were made through Mr. Leonard Harris and
Mr. Stan Clift of Kerr-McGee. Mr. Dennis Holzschuh of the EPA was present
during the tests, as was Mr. Pat Murin of Radian Corporation, who monitored
the plant processes.

2.0 SUMMARY OF RESULTS
Results of the total particulate tests conducted on the cyclone
inlet and scrubber outlet of the potassium chloride drier are shown below
in Tables 2.1 and 2.2, respectively. Two tests were run with the scrubber
operating at a high pressure drop and two tests were also run at low
pressure drop. Under the high pressure drop the scrubber was developing
leaks in the duct leaking to the scrubber, preventing a third test run at
high pressure drop.

Complete particulate results for the three sampling locations are
presented in Appendix A. Field data sheets are included in Appendix B.
Particle size results for the cyclone inlet are shown in tabular
form in Tables 2.4 through 2.7, and graphically in Figures 2.1 and 2.2.
Results for the scrubber outlet are shown in Tables 2.8 and 2.9 and in
Figure 2.3. Four particle size test runs were made at the cyclone inlet.
Runs 1 and 2 were with high scrubber pressure drop, and Runs 3 and 4 with
low scrubber pressure drop. Similarly, two runs were made at the scrubber
outlet with Run 1 at high pressure drop and Run 2 at low pressure drop.
Particle size results for the baghouse outlet are shown in
Table 2.10 and Figure 2.4. Field data sheets for all of the particle size
test runs are included in Appendix B.
Results of the opacity readings taken at the scrubber outlet and
baghouse outlet are summarized in Tables 2.11 through 2.17. The average
opacity at the scrubber outlet was 20% and 15% for Runs 1 and 2 (high
pressure drop), respectively, and 30% for Runs 3 and 4 (low pressure drop).
The average opacity at the baghouse outlet was 5% during all three runs. '
Moisture content averaged 9.8% for the potassium chloride drier feed
and 6.3% for the potassium sul fate drier feed. Results are included in
Table 2.18.

3.0 PROCESS DESCRIPTION
The two processes tested involve the production of potassium
chloride and potassium sulfate. Potassium chloride is dried in a rotary
gas-fired drier as the final step of production before being sent to storage
for packaging. Exhaust gases from the drier pass through two cyclones in
parallel and a venturi scrubber with a moisture dropout chamber before being
released to the atmosphere. Testing of the exhaust gases was conducted
before the cyclones and after the scrubber. Figure 3.1 shows the relative
location of the plant equipment and the sampling locations.
Potassium sulfate is also dried in a rotary gas-fired drier. The
exhaust gases from this drier pass through a baghouse before venting to the
atmosphere. Sampling of the gases was conducted at the baghouse outlet.
Samplinq was not conducted at the inlet to the baghouse because there is no
suitable sampling location. Figure 3.2 shows the arrangement of equipment.

4.0 SAMPLING AND ANALYTICAL PROCEDURES
Gas sampling for total particulate content was conducted at the
cyclone inlet, scrubber outlet, and baghouse outlet in accordance with EPA
Reference Method #5. This method involves the isokinetic extraction of a
sample from the gas stream and collection of the particulate on a heated
out-of-stack filter. A dry gas meter measures the volume of the gas sample.
The gas velocity in the duct is measured during the sampling with a Pitot
tube and inclined manometer. The stack gas temperature is measured with a
chrome!-alumel thermocouple. The quantity of particulate collected is
determined gravimetrically with results reported as grains of particulate
per standard cubic foot of gas.
The samples for particle size distribution at the cyclone inlet,
scrubber outlet and baghouse outlet were collected using an Andersen 2000
in-stack cascade impactor. The particulates are collected by impaction on a
series of plates. The plates have increasingly smaller holes so that the
velocity of the particles is increased from plate to plate and smaller and
smaller particles are impacted. 'The particulate weight collected on each
plate is determined gravirnetrically. The particle size distribution is based
on the equivalent aerodynamic size of the particles based on spherical
particles of 1 gram/cc density. A cyclone preseparator was used on the
Andersen sampler at the cyclone inlet due to the large amount of particulate.
Opacity readings of the scrubber outlet and baghouse outlet gases
were made in accordance with EPA Method #9 by a certified smoke reader.
