NOXSO SO2/NOx flue gas treatment process Proof‐of‐Concept test

Abstract
The NOXSO process uses a regenerable sorbent that removes SO2 and NOx simultaneously from flue gas. The sorbent is a γ alumina bead impregnated with sodium carbonate. The process was successfully tested at three different scales, equivalent to 0.017, 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.
