Selective Catalytic Reduction (SCR)

Emission control treatment, Selective Catalytic Reduction (SCR)

Emissions from power stations or engines typically contain NOx. NOx is a generic term for mono-nitrogen oxides NO and NO2 (nitric oxide and nitrogen dioxide). They are produced from the reaction of nitrogen and oxygen gases in the air during combustion, especially at high temperatures.

In the lower atmosphere, NOx combines with reactive organic gases in the presence of sunlight to form ground-level ozone, which is the primary component of urban smog. In addition, nitric oxide and nitrogen dioxide are components of acid rain, which is a significant problem in the northern hemisphere.

Over the past 20 years, ECI has led the way in Selective Catalytic Reduction (SCR) NOx Abatement Systems in Australia and around the world.
