Selective Catalytic Reduction definition

Selective Catalytic Reduction means a noncombustion control technology that destroys NOx by injecting a reducing agent (e.g., ammonia) into the flue gas that, in the presence of a catalyst (e.g., vana- dium, titanium, or zeolite), converts NOx into molecular nitrogen and water.

Selective Catalytic Reduction or “SCR” means a pollution control device that employs selective catalytic reduction technology for the reduction of NOx emissions.

Selective Catalytic Reduction or “SCR” shall mean an air pollution control device consisting of ammonia injection and a catalyst bed to selectively catalyze the reduction of NOx with ammonia to nitrogen and water.

More Definitions of Selective Catalytic Reduction

Selective Catalytic Reduction and “SCR” shall mean a pollution control device that reacts ammonia (NH3) or urea with NOX to form nitrogen (N2) and water (H2O) using a catalyst to speed the reaction. SCRs include traditional add-on SCRs and catalyst-impregnated ceramic filters.

Selective Catalytic Reduction or “SCR” means an advanced active emissions control technology system that injects a liquid-reductant agent through a special catalyst into the exhaust stream of a diesel engine.

Selective Catalytic Reduction or “SCR” means an emission control system that injects diesel exhaust fluid into the exhaust stream where it reacts with a catalyst to reduce NOx emissions.

Selective Catalytic Reduction or "SCR" means an air pollution control device for reducing NOx emissions in which ammonia ("NH3") is added to the flue gas and then passed through layers of a catalyst material. The ammonia and NOx in the flue gas stream react on the surface of the catalyst, forming nitrogen ("N2") and water vapor. (“U.S. v Consumers Energy Company, Civil Action 14-13580, E.D. Mich., 2014” paragraph 61)

Selective Catalytic Reduction and “SCR” shall mean a pollution control device that employs selective catalytic reduction technology to react ammonia (NH3) with NOx to form nitrogen (N2) and water (H20) using a catalyst to speed the reaction;

Selective Catalytic Reduction is an Element of Design that reduces NOx emissions by chemically converting exhaust gas that contains NOx into nitrogen and water through the injection of diesel exhaust fluid. Sensors in the SCR system communicate with the OBD to ensure that SCR is properly controlling NOx emissions.
