Can an IGCC unit remove CO2?
In the event that rules are put in place that mandate reductions in CO2, an IGCC unit can have equipment added to remove CO2 from the synthesis gas prior to combustion. This is done by modifying the reaction that occurs in the gasifier and then passing the synthesis gas through a chemical reaction similar to that which is used to remove the sulfur. This process is already in service at several gasifiers in use at chemical plants in the U.S. and overseas.
