Description:
The report, part of a series to aid in determining the technological basis for New Source Performance Standards for Industrial Boilers, addresses the use of synthetic fuels produced from coal as a precombustion emission control for new industrial boilers. The synthetic fuels technologies considered include coal gasification and liquefaction. Examining the reduction of SOx, NOx, and particulate emissions in industrial boiler flue gases is emphasized. Two low-Btu gasification systems (the Wellman-Galusha gasifier with either the Stretford (W-G/S) or monoethanolamine (W-B/MEA) acid gas removal process) were selected for the detailed analyses, which involved two coal feedstocks (low-sulfur western and high-sulfur eastern) and five boiler capacities (8.8, 22, 44, 58.6, and 117 MWT heat input). The low-Btu gasification systems met the most stringent target NOx and particulate emissions control levels that were considered. For SO2 emissions, the W-G/S systems using low-sulfur coal achieved a stringent target emission control level of 43 ng SO2/J heat level. Using high-sulfur coal, the W-G/S system achieved a moderate target control level of 150 ng SO2/J heat input. For regulatory purposes, this assessment must be viewed as preliminary, pending results of the more extensive examination of impacts called for under Section III of the Clean Air Act.
