Abstract
Sulfur dioxide (SO) is removed from carbon dioxide feed gas comprising SOas a contaminant by maintaining the carbon dioxide feed gas at an elevated pressure in contact with an alkaline sorbent for a period of time sufficient to react said alkaline sorbent with SO. Where NO, oxygen (O) and water are also present, not only is the rate of reaction with the sorbent increased, but also additional SOis removed by conversion to sulfuric acid, and NOis removed as nitric acid. The method has particular application in the removal of SOand NOfrom flue gas produced by oxyfuel combustion of a hydrocarbon or carbonaceous fuel.
