Application of the SULF-X process to coal conversion and utilization. Phase II final report

PDF Version Also Available for Download.

Description

Pittsburgh Environmental and Energy Systems, Inc. contracted with the Department of Energy to demonstrate the efficacy of an iron sulfide flue gas treatment system (FGT) for removing sulfur dioxide (SO/sub 2/) and nitrogen oxides (NO/sub x/) and to correlate process variables to system performance. Laboratory and bench-scale testing was conducted with the SULF-X process, using both synthesized gas and actual flue gas from a coal-fired furnace. Laboratory tests resulted in 95% SO/sub 2/ removal and up to 95% NO/sub x/ removal. The bench-scale system demonstrated similar SO/sub 2/ removal efficiencies, but achieved only 39% NO/sub x/ removal due to relatively ... continued below

Description

Pittsburgh Environmental and Energy Systems, Inc. contracted with the Department of Energy to demonstrate the efficacy of an iron sulfide flue gas treatment system (FGT) for removing sulfur dioxide (SO/sub 2/) and nitrogen oxides (NO/sub x/) and to correlate process variables to system performance. Laboratory and bench-scale testing was conducted with the SULF-X process, using both synthesized gas and actual flue gas from a coal-fired furnace. Laboratory tests resulted in 95% SO/sub 2/ removal and up to 95% NO/sub x/ removal. The bench-scale system demonstrated similar SO/sub 2/ removal efficiencies, but achieved only 39% NO/sub x/ removal due to relatively high oxygen concentrations in the flue gas and insufficient liquid-gas interfacial area within the absorber. Elemental sulfur was recovered during the regeneration steps. Total capital investment for the SULF-X system was estimated to be $91 to $103 per kilowatt (electric), compared to $90/kw for sodium solution scrubbing, $78 to $83/kw for magnesia slurry scrubbing and $74/kw for limestone slurry scrubbing. Annual operating costs for the SULF-X system were estimated to be 5.44 to 6.90 mills per kilowatt-hour, compared to 4.96 to 5.22 for sodium, 3.68 to 3.99 for magnesia and 3.73 to 4.25 for limestone. 6 references, 6 figures, 9 tables.
