Internal combustion (IC) engine exhaust contains nitric oxide (NO) and nitrogen dioxide (NO2) as well as volatile organic compounds (VOCs) and carbon monoxide (CO). These air pollutants have to be removed from exhaust to comply with local air quality control regulations.
Post-Combustion Emission Control for Biogas Powered Engines
Two approaches that may be capable of complying with future emission limits are Selective Catalytic Reduction (SCR) and NOXTECH
