• <br />Air Emissions Data <br />This section summarizes the emission calculation for AMSO's proposed R&D <br />plant. These calculations are also documented using an electronic spreadsheet (Microsoft <br />Excel format). An electronic copy of the spreadsheet is included on the attached <br />CD-ROM <br />Production Calculations <br />Production of gas oil, naptha, sour water, and product gas were all derived from <br />the amount of oil shale being retorted and shale characteristics. At 4,200 tons of shale <br />being retorted over the R&D project, approximately 600,000 pounds of liquid will be <br />captured from the retort process (based on 20 gallon shale oil per ton at 7.09 lb/gal). <br />Based on the design engineering data, approximately 29% of the shale oil will be <br />recovered as gas oil (171,229 lbs) with 64% as naptha (381,720 lbs). The remainder will <br />be sour water, however at 90% water content (by weight), approximately 400,000 pounds <br />of sour water will be produced. The product gas recovery will be approximately 90% (by <br />weight) of the naptha product at 350,000 pounds. <br />• These production rates for AMSO's R&D project are the basis for the emission <br />calculations described below. <br />Sulfur Coxrpound Emissions <br />Emissions of sulfur compounds from the AMSO thermal oxidizer equipment were <br />estumated using mass balance. <br />Based on the expected shale oil output for the R&D test (2,000 bbl) and the <br />characteristics of oil shale (20 gal oil/ton shale), the mass of oil shale retorted during the <br />R&D test was estimated at 4,200 tons. <br />(2,000 bbl) * (42 gal/bbl)1(20 gal/ton) = 4,200 tons oil shale retorted <br />Based on available data for the shales planned for AMSO's R&D test program, <br />the expected suulfinr content is around 2.0%. However, the calculations use 2.25% sulfur <br />in order to have a margin of safety. <br />4,200 tons shale * 2.25% sulfur = 94.5 tons sulfur available in shale <br />However, available information suggests that 50% or less of the available sulfur is <br />liberated during retorting (See: Occurrence and Reactions of Oil Shale Sulfur, <br />A. Burnham & R. Taylor, Presented at the 15th Oil Shale Symposium, 1982). The rest of <br />• the sulfur is retained in the residual materials. <br />Page 19 of 46
