NOXSO SO2/NOX FLUE-GAS TREATMENT PROCESS PROOF-OF-CONCEPT TEST

The NOXSO process uses a regenerable sorbent that removes SO2 and NO(x) simultaneously from flue gas. The sorbent is a gamma alumina bead impregnated with sodium carbonate. The process was successfully tested at three different scales, equivalent to 0. 01 7, 0.06 and 0. 75 MW of flue gas generated from a coal-fired power plant. The Proof-of-Concept (POC) Test is the last test prior to a full-scale demonstration. A slip stream of flue gas equivalent to a 5 MW coal-fired power plant was used for the POC test. This paper summarizes the NOXSO POC process and its current test results.
