PRIMARY ALUMINUM INDUSTRY
INTRODUCTION ;
| . I
j This document presents a summary of source tests and visible emission
measurements cited in "Technical Report: An Investigation of the Best Systems
of Emission Reduction for the Primary Aluminum Industry." It is concerned
principally with tests for fluorides and visible emissions, but also describes
the facilities from which data have been obtained, their operating conditions,
and:characteristics of exhaust gas streams.
l . i
Facilities are identified by the same coding used in the Technical Report
i . '
(excjept as noted in the facility descriptions). For example, Table 1 (Facility A,)
summarizes results of EPA's May 1972 measurements of primary emissions from Plant
i i
A. jThese same results are also plotted in Figure 11 of the Technical Report
identified as Plant A-,.
j Many of the tests summarized herein were conducted us i rig EPA Method 13
for [fluorides. This method will be proposed in the Federal Register at the
time)of proposal of standards of performance for new or substantially modified
primary aluminum plants. !
-------
Fluoride Test Results
A program was undertaken by EPA to evaluate the best control techniques
available for controlling fluoride emissions from primary aluminum plants.
The data obtained serves as input to development of standards of performance
for primary aluminum plants being proposed under section 111 of the Clean
Air Act of 1970.
Preliminary investigation revealed the locations of a number, of reportedly
well controlled plants. Eight of these were visited to obtain further information
on the process and air pollution control equipment. Six plants were selected
for emission tests. These plants represented all three types of reduction cells
and a variety of air pollution control systems. Two of these plants were later
retested. Two other plants were inspected in Europe, and emission data was
furnished by their owners. Additional data was obtained from American aluminum
companies and from state air pollution control agencies.
Figures 1, 2, and 3 present a visual comparison of the data.
Facilities
Potroom Facilities
A. Plant A is a vertical stud Soderberg plant with a production capacity
- - ofl88sOOO;*t6ns"p^Fye&r°6f aluminum. The plant'has two pot lines with
150 cells (pots) per line housed in four,potrooms. The primary emission
control system consisted of a "bubbler" scrubber followed by a wet
-------
electrostatic precipitator. The secondary system consisted of a
spray screen scrubber at the roof monitors. The primary emissions
were tested twice by an EPA contractor (tests'A. and A.) using EPA
Method 13 for fluorides. Additional primary emission data, results
of emission measurements performed by the company, were furnished
by a state agency (A3). Secondary emissions were tested by EPA
contractors three times. Jests A, and A were performed in
I £
conjunction with the.respective primary emission tests A. and A.,
while test A was performed on a separate occasion. Additional
secondary emission data:from company tests was provided by a state
agency (A3) and by the company itself (A ). EPA Method 13 was used
for tests A and A,, of secondary emissions. Company test methods
were used for the other secondary emission tests.
B. This is a horizontal stud Soderberg plant with a production capacity
of 190,000 tons per year of aluminum. The newer portion of the plant
tested consisted of three potlines with 168 ce;lls per line housed in
six potrooms. The primary emission control system used at this plant
consisted of a venturi scrubber using a caustic solution, so that
I
the fluoride can be recovered, followed by a wet electrostatic
precipitator: The plant did not use a control-system fon.secondary
emissions. Primary and secondary emissions were both tested at this
plant by an EPA contractor using EPA Method 13 (tests designated B).
Additional data on primary and secondary emissions (designated B,)
were provided by the company. The test method used by the company
is not known.
-------
C. This is a prebake plant with a production capacity of 175,000 tons
per year of aluminum. Aluminum is produced from five pot! ines with
about 156 cells per line. The primary emission control system used
on the potroom tested was a fluid bed dry scrubber Using alumina
as the scrubbing medium and a baghouse as the collector. The plant
did not use a control system for secondary emissions. Primary and
secondary emissions were both tested at this plant using EPA Method
13. " -' - ' '- "' "" '? ........... ;»---; .......... .- <; -M.+ ««'*
D. This is a prebake plant with a production capacity of about 120,000
tons per year of aluminum. Aluminum is produced from two pot! ines
*
containing 124 cells per line. The potlines are housed in four
potrooms. The primary emission control system used on the potroom
tested was a fluid bed dry scrubber using alumina as the scrubbing
medium and a baghouse as the collector. The plant did not use a
control system for secondary emissions. Primary emissions were
tested twice by EPA (tests designated D and D^) and secondary.
emissions were tested once. EPA Method 13 was used to conduct all
tests. Visible emission data for both primary and secondary emissions
were obtained by EPA and contractor personnel using EPA Method 9 on
another occasion.
E. These data are not specific tosawy dfle^1ari%-J but 'are primary and
secondary emission data provided by the owner of Facilities C and D.
Tests were conducted. using the company's own test method. r- --
-------
F. This is a'European vertical stud Soderberg plant which produces
about 25,000 metric tons of aluminum per year, j Aluminum is
produced from one potroom containing 88 cells. The primary
emission control system consists of cyclones in series with
fluid bed dry scrubbers using alumina as the scrubbing medium
and baghouses as collectors. Secondary emissions are controlled
by scrubbing towers using sea water as the scrubbing medium.
Gas from the primary control system is also routed through the '"
secondary system scrubbers. Both primary and secondary control
systems were tested by the owner of the plant. Only primary
r
emission data are utilized. Test methods are uiiknown.
G.
H.
This is a European plant using prebake cells which produces about
80,000 metric tons of aluminum per year from 216 cells. A dry
*
primary emission control system is used. There is no secondary
emission control system. Both primary and secondary emission
data were provided by the owner. Test methods are unknown.
(Secondary emission data for this facility is coded as "Plant F"
in Figure 12 of the Technical Report.)
This plant uses prebake cells and produces 265,000 tons of aluminum
per year. The primary control system is an injected alumina dry
; ' I.
scrubber. Secondary control;is by^aopowered concurrent spray scrubber.
Both primary and secondary emission data was submitted by a state air
pollution control agency. The test method is unknown. (Secondary
emission data for this facility is coded as "Plant G" in Figure 12
- . . i.
of the Technical Report.)
-------
Anode Plants
A. This plant started production late in 1970 and has a production
capacity of about 75,000 tons per year of anodes. Anodes are
produced by crushing and sizing the raw material, coke, and mixing
it with pitch (tar). The anode blocks are produced in a hydraulic
unit which presses the coke-tar mixture into blocks. The blocks
are then placed in the anode furnace to bake for about 30 days
at 1100-1200°C. The emissions from the anode bakTfuWace are
collected in two parallel 54-inch ducts which are each connected
to a water spray tower and electrostatic precipitators in series.
The water spray towers condense much of the tar in the gases and
closely controls the temperature of the gases entering the electro-
static precipitator. After the spray towers and precipitators,
the gas stream!is combined and is discharged from a 2.7 meter
(nine-foot) diameter, 53 meter (175 feet) high stack. This facility
was tested by EPA using Method 13 for fluorides. Visible emission
data were obtained using EPA Method 9 by EPA and contractor
personnel on a separate occasion.
B. This plant started production of anodes in 1971 with a production
capacity of about 230,000 tons per year of anodes. Anodes are
produced by crushing and sizing the raw material, coke, which
is then mixed with pitch (tar). The anode blocks are produced in
a vibrator unit which!compacts the coke-tar mixture into blocks.
The blocks are then placed in the anode furnace to bake for about
-------
30 days at n50-1200°C. The emissions from the anode furnace are
i
collected in two 54-inch ducts which join together at a water spray
conditioning chamber. The chamber condenses much of the tar and
i.
provides close temperature control of the gas stream entering the
'l
electrostatic precipitator. The gas discharges through a 30 meter
' u
(100 foot) stack. This facility was tested by EPA contractors
using EPA Method 13.
