Document Type and Number:
WIPO Patent Application WO2004030797
Kind Code:
B1
Abstract:
A method of scrubbing SOx, NOx compounds and other air toxins from a flue gas stream. In the method, two distinct unit operations are amalgamated to scrub SOx, NOx and other air toxins compounds from a flue gas stream. More specifically, there is a dry scrubbing operation and a wet scrubbing operation. The dry injection scrubbing operation involves contacting a flue gas stream containing SOx and NOx compounds with a sorbent for removing substantially all of the SOx and NOx compounds present in the stream. The second wet scrubbing operation involves contacting the stream to remove any residual SOx, NOx compounds, and other air toxins remaining in the stream.
