Dc. Baker, PROJECTED EMISSIONS OF HAZARDOUS AIR-POLLUTANTS FROM A SHELL COAL-GASIFICATION PROCESS COMBINED-CYCLE POWER-PLANT, Fuel, 73(7), 1994, pp. 1082-1086
An integral part of the development programme for the Shell coal gasif
ication process (SCGP) has been the determination of hazardous air pol
lutants (HAPs) and other trace constituents in the process syngas. Num
erous results at the Shell Coal Gasification Plant-1 (SCGP-1) verify t
hat very few HAPs or any other trace constituents are present in the s
yngas, and the concentrations of those few species present are extreme
ly low. These results from direct measurements on the syngas are subst
antiated by analyses of other process streams and by inspection of syn
gas clean-up equipment and transport lines during decommissioning. The
results are used to project emissions of HAPs and other trace constit
uents for a 500 MW SCGP-combined-cycle power plant. Not only would suc
h a facility not be defined as a major source of HAPs, but in fact it
might even establish a benchmark (based on low HAP emissions) for new
coal-based power generation.
