Emissions Control Technology

SCONOX

Overview

The SCONOX system is a new catalytic reduction technology that has been developed and is currently being made available for natural gas-fired turbines. It is based on a unique integration of catalytic oxidation and absorption technology. CO and NO are catalytically oxidized to CO 2 and NO 2 . The NO 2 molecules are subsequently absorbed on the treated surface of the SCONOX catalyst. The system manufacturer, EmerChem, guarantees CO emissions of 1 ppm and NOx emissions of 2 ppm. The SCONOX system does not require the use of ammonia, eliminating the potential of ammonia slip conditions evident in existing SCR systems. Only limited emissions data were available for a gas turbine equipped with a SCONOX system. This data reflected HAP emissions and was not sufficient to verify the manufacturer’s claims.
