All testing was conducted during the period 23 to 26 June 1980 by Weston Air Measurement Services personnel. -4- ------- PROCESS DESCRIPTION The Sherwin facility is located approximately 15 miles north of Corpus Christi on the Gulf Coast of Texas. This facility proc- esses bauxite imported from Caribbean and South American coun- tries. Bauxite is transported to the facility in ships carrying from 15,000 to 50,000 tons. Bauxite is unloaded from the ships by one of two mechanisms. Most ships are designated as "self-unloading." As such, they have a self-contained extendable boom conveyor that interfaces with a dockside conveyor belt via an accordian chute. Smaller ships require the services of a dockside extendable boom convey- or that is inserted into the side of the ship. Only a self- unloading ship was tested during the test sequence reported here. From the dock, bauxite is conveyed to a covered "live" ore stor- age area. Bauxite is then reclaimed from the storage area and conveyed to one of four storage bins. Each storage bin feeds a rod mill, although not all rod mills are operated simultane- ously. Product from the rod mill is processed through a modi- fied Bayer refining system. All processes from the rod mill up to, but not including, the final calcination of alumina are wet processes and do not emit particulate matter. After calcination of alumina the product is transferred by railcar to the dock area where the alumina is dumped from the bottom of railcar hop- pers onto a tunnel conveyor. From the railcar dump alumina can be conveyed either directly to a ship-loading tower or to one of three temporary storage bins. From the ship-loading tower alu- mina is dumped through an accordian chute into the hold of a ship or barge for shipment to reduction plants in various parts of the country. SHIP UNLOADING Emission Control From the standpoint of particulate-emission control, the ship unloading facility is simply a conveyor transfer point with a fairly long free-fall zone (20 to 30 feet between conveyor belts via an accordian chute). Both the extendable boom conveyor from the ship and the dockside conveyor are enclosed. Emission control is primarily affected by ducting air from the base of the accordian chute and from -5- ------- the impact zone on the dockside conveyor belt. Approximately 20rOOO cubic feet per minute (cfm) are ducted to a dry cyclone and then to a venturi scrubber. An additional 70,000 cfm are ducted directly from the transfer point to the venturi scrubber. Design pressure drop across the scrubber is 15 inches (water); the system manometer was not functioning during the test. Ship Unloading Test Points The following points were tested at the ship unloading facility. At the combined inlet duct for the venturi scrubber Method 5 (one test) measurements were taken. At the outlet of the venturi scrubber Method 5 (one test), Method 9 (one test), and particle size distribution measurements were taken. Visible emission measurements were also made at points which were indicative of the capture efficiency of the emission control system. Accordingly, Method 9 and draft Method 22 readings were taken at the interface of the accordian chute and the top of the dockside conveyor shed, and at an open doorway in the dockside conveyor shed. This doorway was located approximately 10 feet from the duct pickup points at the impact zone on the dock conveyor belt. Visible emissions measurements at this point measured the amount of emissions which escaped through the doorway into the open environment. Test Conditions During the test period ore was unloaded at a rate of 1,500 to 1,700 tons per hour (normal rate). Actual measurements were not possible due to a malfunction of the strip chart recording the unloading rate. Plant personnel verified that the unloading operation proceeded normally. ORE STORAGE BIN Emission Control Particulate emissions from ore bins No. 1 and No. 2 (preceding the rod mills) are ducted separately to individual baghouses. Both baghouse outlets are combined in a common stack. Typically only one bin is filled at a time, although both baghouses run continuously. The baghouses are located directly over the fine ore bins; therefore, no measurements could be taken of the inlet loadings to these baghouses. Each baghouse is designed for a flow rate of 7,000 cfm and an air-to-cloth ratio of 8 to 1. -6- ------- Test Points Method 5 readings were taken at the outlet of the baghouse on the No. 2 ore bin. Method 5f Method 9, and particle size dis- tribution tests were taken at the combined outlet of the No. 1 and No. 2 baghouses. In addition, Method 9 and Method 22 readings were taken in the area of the baghouses at the top of the ore bins. Test Conditions Because ore bin No. 2 was filled with a type of ore that is less dusty than the normal mill feed, it was decided to test during the filling of ore bin No. 1 only. Tests were conducted during a continuous draw and fill of ore bin No. 1 in order to maximize emissions during the test period. Fill rate varied between 425 and 475 tons per hour, which is the normal range. -7- ------- DESCRIPTION OF TEST LOCATIONS SHIP UNLOADING SCRUBBER INLET DUCT Two 3-inch I.D. test ports, 90° apart, were placed on a straight section of the 54-inch I.D. metal duct at a location approximately 72 inches downstream and 14 inches upstream from the nearest flow disturbances.

FIGURE 4 NO. 2 FINE ORE STORAGE BIN BAGHOUSE EXHAUST DUCT - PORT AND SAMPLING POINT LOCATIONS -12- ------- ' DESCRIPTION OF SAMPLING TRAINS PARTICULATE SAMPLING TRAINS The test train utilized for particulate sampling of all test locations was the standard EPA Method 5 train (see Figure 5). A stainless steel nozzle was attached to a heated (— 250°F) borosilicate probe which was connected directly to a borosili- cate filter holder containing a 9-cm Reeve Angel 900 AF glass fiber filter. The filter holder was maintained at approximately 250°F in a heated chamber, and was connected by vacuum tubing to the first of four Greenburg-Smith impingers which were included in the train to condense the moisture in the gas stream. Each of the first two impingers contained 100 ml of distilled water, the third was dry, and the final impinger contained 200 grams of dry preweighed silica gel. The first, third, and fourth impingers were modified Greenburg-Smith types; the second was a standard Greenburg-Smith impinger. All impingers were maintained in a crushed ice bath. A Nutech con- trol console with vacuum pump, dry gas meter, a calibrated ori- fice, and inclined manometers completed the sampling train. Flue gas temperature was measured by means of a calibrated Type K thermocouple which was connected to a direct readout pyrom- eter. The thermocouple sensor was positioned adjacent to the sampling nozzle. Gas velocity was measured using a calibrated S-type pitot tube provided with extensions and fastened alongside the sampling probe. Gas stream composition (carbon dioxide, oxygen, and car- bon monoxide content) was determined utilizing an Orsat appara- tus. PARTICLE SIZE DISTRIBUTION SAMPLING APPARATUS A stainless steel nozzle was connected directly to an 8-stage Andersen cascade impaction device which separated the particles according to their effective aerodynamic particle diameters. A solid glass fiber filter was used to capture any particles that passed through the impactor substrates to permit the measurement of total particulate. The filter holder was maintained at stack temperature, and was connected by vacuum tubing to the first of four Greenburg-Smith impingers which were included in the train to condense the moisture in the gas stream. All impingers were maintained in a crushed ice bath. An RAC control console with vacuum pump, dry gas meter, a calibrated orifice, and inclined manometers completed the sampling train. See Figure 6 for a schematic of the particle sizing apparatus. -13- ------- .TEMPERATURE SENSOR THERMOMETER CHECK VALVE VACUUM LINE 'ACUUM GUAGE THERMOMETERS HEATED AREA FILTER HOLDER NOZZLE/HEATED - PROBE REVERSE TYPE PITOT TUBE PITOT MANOMETER ORIFICE AND MANOMETER IMPINGERS ICE BATH FIGURE 5 PARTICULATE SAMPLING TRAIN-EPA METHOD 5 ------- Thermometer Nozzle I M Ul Reverse-Type Pilot Tube Pilot Manomeler Orifice hermometers Bypass Valve lingers \ Ice Balh Vacuum Gauge Air Tighl Pump Check Valve Vacuum Line FIGURE 6 PARTICLE SIZE DISTRIBUTION SAMPLING APPARATUS - ANDERSEN 2000, INC. ------- TEST PROCEDURES PRELIMINARY TESTS Preliminary test data were obtained at each sampling location. Stack geometry measurements were recorded and sampling point distances calculated. A preliminary velocity traverse was per- formed at each test location utilizing a calibrated S-type pitot tube and a Dwyer inclined manometer to determine velocity profiles. A check for the presence or absence of cyclonic flow was conducted at each test location prior to formal testing. Stack gas temperatures were observed with a direct readout pyrometer equipped with a chromel-alumel thermocouple. Preliminary test data were used for nozzle sizing and nomagraph set-up for isokinetic sampling procedures. Calibration of the probe nozzles, pitot tubes, metering systems, probe heaters, temperature gauges, and barometer were performed as specified in Section 5 of EPA Method 5 test procedures (see Appendix D for calibration data). FORMAL TESTS Ship Unloading Scrubber Inlet Duct A single test was conducted at the Ship Unloading Scrubber Inlet Duct to measure the concentration and mass rate of particulate matter emissions. Forty-eight traverse points (24 per axis) were sampled for two minutes each, resulting in a total test time of 96 minutes. During particulate sampling, gas stream velocities were measured by inserting a calibrated S-type pitot tube into the stream adjacent to the sampling nozzle. The velocity pressure differential was observed immediately after positioning the noz- zle at each point, and sampling rates were adjusted to maintain isokinetic sampling. Stack gas temperatures were also monitored at each point with the pyrometer and thermocouple. Additional temperature measurements were made at the final impinger, and at the inlet and outlet of the dry gas meter. Test data were recorded at each traverse point during all test periods. Leak checks were performed according to EPA Method 5 instructions prior to and after each run and/or component change. Table 1 presents a summary of test data and test result summarization appears in Tables 2 and 3. -16- ------- Ship Unloading Scrubber Discharge Duct One Method 5 test was conducted at the Ship Unloading Scrubber Discharge Duct simultaneous with the inlet testing. Forty-eight points were traversed (24 per axis) for two minutes each, yielding a test period of 96 minutes. Procedures for isokinetic sampling were identical to those described in the Ship Unloading Scrubber Inlet Duct section. See Tables 1, 2, and 3 for test data and test result summaries, respectively. One sampling point located at a site of average velocity was selected from particulate traverse data for one particle size distribution test. During this test the gas stream was sampled isokinetically at that point for 95 minutes, which permitted collection of sufficient sample for analysis without overloading the filter substrates. See Table 10 for data and results, and Figure 7 for the distribution plot. Visual determinations of plume opacity were performed by a cer- tified observer according to Method 9 procedures. A summary of results is presented in Table 13. No. 2 Fine Ore Storage Bin Baghouse Exhaust Duct Three Method 5 tests were performed on the No. 2 Fine Ore Storage Bin Baghouse Exhaust Duct. A total of 32 points were sampled (16 per port) for three minutes each, yielding a test period of 96 minutes. Isokinetic sampling procedures were identical to those previous- ly described. Table 4 shows test data summarization and Tables 6 and 7 present test results. Visual determinations of plume opacity were performed in accord- ance with EPA Method 9 procedures. Table 14 presents a summary of results. Fugitive emissions determinations were also conducted at this location according to EPA Method 22 procedures. A summary of results is presented in Table 19. -17- ------- No. 1 and No. 2 Fine Ore Storage Bins Exhaust Stack Three Method 5 tests were performed on the No. 1 and No. 2 Fine Ore Storage Bins Exhaust Stack. Twelve points were traversed (six per axis) for eight minutes each, resulting in a test period of 96 minutes. Samples were collected concurrently with those at No. 2 Fine Ore Storage Bin Baghouse Exhaust Duct. Isokinetic sampling procedures were identical to those previous- ly described. Table 5 shows test data summarization and Tables 8 and 9 present test results. Two particle size distribution tests were conducted at a point of average velocity. The first particle size distribution test was 90 minutes in length and the second test was 180 minutes in duration. Sample volume, temperature, and pressure data were recorded at five-minute intervals. See Tables 11 and 12 for test data and test result summaries, and Figures 8 and 9 for distribution plots. Visual determinations of plume opacity were performed by a cer- tified observer according to Method 9 procedures. Result sum- maries are presented in Table 15. Ship Unloading Platform Ship Unloading ConveyoF Belt Tailings Pond No. 2 Bed Plume opacities were recorded at these locations in accordance with EPA Method 9 procedures. See Tables 16, 17 and 18 respec- tively for a summary of results. Fugitive emission frequencies were also recorded at these loca- tions according to EPA Method 22 procedures. Table 19 presents a summary of these results. -18- ------- ANALYTICAL PROCEDURES PARTICIPATE SAMPLE RECOVERY At the conclusion of each test, the sampling trains were disman- tled, openings sealed, and the components transported to the field laboratory. Sample integrity was assured by maintaining chain-of-custody records, which will be supplied on request. A consistent procedure was employed for sample recovery. 1. The glass fiber filter(s) was removed from its holder with tweezers and placed in its original container (petri dish), along with any loose particulate and filter fragments (sample type 1). 2. The probe and nozzle were separated, and the internal particulate rinsed with acetone into a borosilicate container while brushing a mini- mum of three times until no visible particles remained. Particulate adhering to the brush was rinsed with acetone into the same contain- er. The front half of the filter holder was rinsed with acetone while brushing a minimum of three times. The rinses were combined (sam- ple type 2) and the container sealed with a Teflon-lined closure. 3. The total liquid in impingers 1, 2, and 3 was measured, the value recorded, and the liquid discarded. 4. The silica gel was removed from the last impinger and immediately weighed. 5. An acetone sample was retained for blank analysis. PARTICIPATE ANALYSIS The filters (sample type 1) and any loose fragments were oven dried at 105QC for two to three hours, cooled in a desiccator, and weighed to the nearest 0.1 milligram to constant weight. The acetone wash samples (sample type 2) were evaporated at ambient temperature in tared beakers, and desiccated at ambient temperature and pressure to a constant weight. All sample resi- due weights were adjusted by the acetone blank value. -19- ------- The weight of the material collected on the glass fiber filter(s) plus the weight of the residue of the acetone nozzle/ probe/front-half filter holder washes represents the total EPA Method 5 catch. Complete laboratory results are presented in Appendix B of this report. PARTICLE SIZE SAMPLE RECOVERY AND ANALYSES The cascade impactor substrates and any loose fragments were carefully removed from their support plates with tweezers and placed in individual containers (petri dishes) for shipment to Weston's laboratory. Each cascade impactor filter was fired at 525°C and pre- weighed to the nearest 0.1 milligram to constant weight at Weston's laboratory prior to on-site application. Subsequent to emissions exposure, the cascade impactor substrates, back-up filters, and any loose fragments were oven dried at 105°C for two to three hours, cooled in a desiccator, and weighed to the nearest 0.1 milligram to constant weight. -20- ------- TEST RESULTS AND DISCUSSION Particulate test data and test result summaries are presented in Tables 1 through 9 of this section. Tables 10 through 12 contain data and results of the particle size distribution tests; Figures 7 through 9 show the distribution plots. Tables 13 through 18 present plume opacity determination results and Table 19 shows fugitive emission test results summaries. The quantity of particulate matter measured during the one test at the Ship Unloading Scrubber Inlet Duct was 1.14 grains/DSCF and 806 pounds/hour. The particulate matter discharged to the atmosphere from the Ship Unloading Scrubber Discharge Duct was 0.017 grains/DSCF and 12.6 pounds/hour. The Ship Unloading Scrubber particulate removal efficiency was 98.4 percent. The particulate matter discharged from the No. 2 Fine Ore Storage Bin Baghouse Exhaust Duct was <0.004 grains/DSCF and < 0.218 pounds/hour. The particulate matter discharged from the No. 1 and No. 2 Fine Ore Storage Bins Exhaust Stack was < 0.004 grains/DSCF and <0.482 pounds/hour. It should be noted that only one test set was run at the Ship Unloading Scrubber. Weston test personnel were directed by the EPA Administrator not to conduct further testing at this site due to high plume opacities recorded at the Scrubber Discharge Stack by the Weston certified observer. As per instructions by Mr. Dennis P. Holzschuh, EPA Task Manager, certain samples obtained by Weston test personnel were released to York Research Corporation for trace metals analysis.
