A performance standard is based on the best emission reduction systems which have been shown to be technically and economically feasible. In order to set realistic performance standards, accurate data on pollutant emissions is normally gathered from the stationary source category under consideration. The gypsum plant of the Flintkote Company at Blue Diamond, Nevada, is equipped with a system for particulate emission reduction and was selected for testing as part of the nonmetallic minerals industry study. The testing was performed by Midwest Research Institute (MRI) dur- ing the period of October 25 to October 29, 1976, at the Flintkote Company Plant, Blue Diamond, Nevada. The plant manufactures gypsum boards. The gyp- sum is mined from a nearby gypsum mine, milled, calcined, and recombined with water to form gypsum boards. Natural gas, No. 2 fuel oil and/or elec- tricity are used to energize the process. The milling process is the process of interest. Part of the output flow from each of the five mills is vented to the atmosphere through a baghouse. Figure 1 is a schematic illustration of the gas flow around a typical mill. Samples were drawn from two locations: inlet and outlet of the baghouse of Mill No. 2. In summary, MRI tests conducted for this project consisted of: 1. Three mass particulate (Method 17) runs at the outlet of the baghouse. 2. One mass particulate (Method 17 preceded by alundum thimble) run at the inlet to the baghouse. 3. Opacity reading (Method 9) of the baghouse outlet emission for the duration of each particulate test. 4. Opacity reading (Method 9) around the mill area, inside the plant. ------- Roof From Cyclone Separator Extension Outlet Ports Baghouse Gas Fired Heater To Cyclone Product Separator Gypsum Feed Raymond Mill Figure 1 - Schematic Illustration of the Gas Flow Around Mill No. 2 ------- No parallel test for particulate was conducted by the plant per- sonnel during the testing period. Section II of this report is a summary and discussion of results. Section III presents the location of sampling points* Section IV presents the sampling and analytical procedures. The appendices comprise raw field data, as well as results of the analysis. II. SUMMARY AND DISCUSSION OF RESULTS Several process problems occurred during the testing periods. These problems forced the cancellation of two tests and the delay and in- terruption of other tests. Table 1 lists these process problems and the action taken to alleviate problems during the tests. Appendix A contains the analytical data for the particulate sam- ples. The field log is contained in Appendix B. A. Particulate Tests Four particulate runs were accomplished: three outlet runs and one inlet run. Tables 2 and 3 present a summary of the results for these runs in metric and English units, respectively. The filterable particulate data include the catches on the nozzle and filter. The total particulate data include the filterable particulate, probe and impinger catches (see Table A-l, Appendix A)« Due to the heavy concentration of particulate in the inlet duct, the probe nozzle was plugged several times during the inlet run. Therefore, the data from this run are biased toward small particles. The inlet run was not conducted simultaneously with any of the outlet runs. Also note that the flow rate determined at the inlet was less than the outlet average. A computer printout of the particulate sampling parameters and loading is contained in Appendix C. Appendix D contains sample calculations of particulate emissions. The particulate field data are contained in Ap- pendix E. ------- TABLE 1 SUMMARY OF PROCESS PROBLEMS Run 1-0 1-0 1-0 2-0 3-0 1-1 Time Date 10/26/76 10/26/76 10/27/76 10/27/76 10/28/76 10/28/76 Begin 1350 1519 0847 1010 1310 0834 1121 End 1409 1527 0954 1014 1351 0930 1453 Description of Counter Description of Problem Action to Problem Mill No. Mill No. Mill No. Mill No. Mill No. Mill No. Mill No. 2 down 2 down 2 down 2 down 2 down 2 down 2 down Test was scrubbed Test was scrubbed Test was interrupted Test was interrupted Test was interrupted Test was interrupted Test was interrupted al 1-0 = Run No. 1-Outlet 1-1 = Run No. 1-Inlet. ------- TABLE 2 SUMMARY OF RESULTS IN METRIC UNITS Run No. Date Sampling Location a/ Volume of gas sampled, dscnr- Percent moisture by volume . o 3/ Average stack gas temp., C Stack gas volumetric flow rate Stack gas volumetric flow rate Percent isokinetic Filterable Particulate (Nozzle m b/ mg/dscnr~ mg/ acmS.' kg/hrb/ Total Particulate (Filterable. mg mg/dscm mg/ acm kg/hr Percent impinger catch 1 10/27/76 Outlet 1.653 4.6 , 63.0 a/ , dscimr-' 100.3 , acmm£/ 128.8 103.6 and Filter) 269.50 162.73 126.73 0.979 Probe and Imoineers) 276.50 166.95 130.02 1.004 2.53 2 10/27/76 Outlet 1.610 1.8 63.9 98.7 123.6 102.6 231.50 143.44 114.61 0.850 237.20 146.98 117.43 0.870 2.40 3 10/28/76 Outlet 1.524 2.6 62.9 96.9 121.9 98.9 231.30 151.42 120.38 0.880 237.60 155.54 123.66 0.904 2.65 l 10/28/76 Inlet 1.882 0.0 75.3 60.8 77.3 99.1 14,762.20 7,827.25 6,160.30 28.561 14,776.70 7,834.93 6,166.36 28.589 0.10 aj dscm = Dry standard cubic meters C = Degrees Celsius dscmm = Dry standard cubic meters per minute acmm = Actual cubic meters per minute W mg/dscm = Milligrams per dry standard cubic meter acm = Actual cubic meter kg/hr = Kilograms per hour ------- TABLE 3 SUMMARY OF RESULTS IN ENGLISH UNITS Run No. Date Sampling Location a/ Volume of gas sampled, dscf Percent moisture by volume . o «*/ Average stack gas temp., F .

Coulter Counter technique was used to size the particulate* The aperture size was 140 \im and the sample materials were dispersed in isopropyl alcohol with 4% Ntfy CNS as the electrolyte. The results of the particle size analyses of the inlet and outlet samples are plotted in Figures 2 and 3, respectively. Appendix F contains Battelle's write up of these results. C. Visible Emissions Measurements Opacity readings were recorded from the discharge point of the tested No. 2 mill for the duration of the particulate tests. Also, visible emissions observations were conducted around the Mill No. 2 area inside the plant with each observation point manned by one observer. Table 4 presents a summary of the visible emission results taken from the discharge point of Mill No. 2 baghouse. Opacity readings taken in- side the plant around Mill No. 2 area are summarized in Table 5. The aver- age percent opacity was below 7% for the baghouse discharge. The average percent opacity for the mill area was 0. Appendix G contains the field data sheets of the observer loca- tions and readings. ------- oo 100 80 O 8 v N c O 60 40 20 0 1.0 -\ \\ Thimble and Nozzle Dry Catch O Back Up Filter O \ I i i I I I i i O* - Particle Size, Microns i i i 100 Figure 2 - Particle Size Distribution of the Inlet Run ------- ioo so U O o 60 0> N c o £40 £ O 20 1.0 I I I I I 10 Particle Size, Microns O Run No.l A Run No.2 Run No.3 I I I I 100 Figure 3 - Particle Size Distribution of the Outlet Runs ------- TABLE 4 FACILITY Summary of Visible Emissions UJtc: 10/27/76 Typ-i Of Plant: Gypsum board manufacturer Type of Discharge: Particulate Distance from Observer to Discharge Point: 25 ft Location of Discharge: Ab-ove plant roof Height of Observation Point: Roof level Height of Point of Discharge: 6 ft above roof Direction of Observer from Discharge Point: 225° (s.w.)

LOCATION OF SAMPLING POINTS There were two sampling locations: the inlet and outlet of the baghouse (Figure !) A* Inlet to the Baghouse A schematic illustration of the sampling location at this inlet is shown in Figure 4. Two sampling ports, fabricated by MRI and installed by the plant, are located at a distance of 39 in. (3 duct diameters) down- stream and more than 26 in. (< 2 duct diameters) upstream from any flow disturbance in the duct. These two ports are 90 degrees apart and located in a plane perpendicular to the flow. Table 6 gives information on the location of the particulate tra- verse points. The number of traverse points was determined according to Method 1 of the Federal Register. B. Outlet of the Baghouse Figure 5 is a schematic illustration of the outlet duct. The dis- tance between the roof and the outlet of this duct was too short to comply with the minimum requirements of Method 1 of the Federal Register. There- fore, MRI fabricated and installed an extension to this duct (Figures 1 and 5). Two sampling ports are located in the extension part of the duct and at a distance of more than 8 diameters downstream and 2 diameters up- stream from any flow disturbance. These two ports were 90 degrees apart and located in a plane perpendicular to the flow. The location of the particulate traverse point and their distances are given in Table 7. The number of traverse points was determined according to Method 1 of the Federal Register. 16 ------- To Baghouse No Flow Disturbance for More than 2 Diameters Sampling * Ports (4") Mill, Cyclone ^Product Separator ^ Ground Figure 4 - Schematic Illustration of the Inlet Duct 17 ------- TABLE 6 LOCATION OF PARTICULATE TRAVERSE POINTS (INLET DUCT) Traverse Point No. 1/15 2/16 3/17 4/18 5/19 6/20 7/21 8/22 9/23 10/24 11/25 12/26 13/27 14/28 Percent of Stack I.D. 1.8 5.7 9.9 14.6 20.1 26.9 36.6 63.4 73.1 79.9 85.4 90.1 94.3 98.2 Stack I.D.

SAMPLING AND ANALYTICAL PROCEDURES Methods 1 through 4 of the Federal Register (Vol. 36, No. 247, December 23, 1971) and Method 17 of the Federal Register (Vol. 41, No. 187, September 24, 1976) were followed in the sampling and analysis of particu- late runs from the inlet and outlet duct. However, a alundum thimble was inserted in front of the filter of Method 17 train for the inlet sampling run. The back half of each train was analyzed according to Method 5 of the Federal Register (Vol. 36, No. 159, August 17, 1971). A schematic illustra- tion of the train used is given in Figure 6. Preliminary velocity and moisture contents of the flue gas were determined, according to Methods 2 and 4 of the Federal Register, before the actual test was started. The data from the preliminary run were used to set the sampling equipment for isokinetic sampling. Eight traverse points were used to sample from the outlet duct. The sampling time at this outlet was 11 min per traverse point for a total of 88 min. The inlet duct was divided into 28 traverse points. The sampling time at this duct was 3 min per traverse point for a total of 84 min. Gas sampling for flue gas compositions was done from the partic- ulate ports. Method 3 of the Federal Register was followed in sampling and analyzing for CO, C02, 02, and N2» 20 ------- Temperature Sensor x = y = 1.9cm (0.75 in).
