Efficient pollutant removal

Pre-CombustionPM, Hg, Su

Pulverized coal

• Pollutants are removed after the coal is

burned

• The gas volume treated is 300 times the gas

volume of an IGCC plant

• Criteria and HAPS emissions are above

an average IGCC plant

• Combustion produces large quantities of

waste and consumes more water than IGCC

IGCC

• Gasification cleans the syngas before

combustion

• High pressure and low volume provide

favorable economics for pollutant

removal

• IGCC offers increased fuel diversity,

reduced emissions, and increased

siting and permitting flexibility

SulfurLowest permitted sulfur emissions from a U.S. coal plant today• Emits 0.01 lb/MMBtu• Best PC is 0.05 lb/MMBtu

MercurySuperior, cost-efficient Hg removal

NOX Lowest NOX permitted plant using bituminous coals today in the US• Emits 0.02 lb/MMBtu• Best PC is 0.05 lb/MMBtu

• 62% less CO

• CO2 capture ready

• 33% less NOx

• 75% less SOx
