Diesel Exhaust Fluid (DEF) Q & A - Cummins Filtration

What is Selective Catalytic Reduction (SCR)? A. SCR is a technology that uses a urea based diesel exhaust fluid (DEF) and a catalytic converter to significantly reduce oxides of nitrogen (NOx) emissions. SCR is the leading technology being used to meet 2010 emission regulations. Q. How does an SCR system work?

Catalytic reduction can be used in conjunction with other NO x emission controls. Other advantages include the capability to operate at any pressure and the option of heat recovery to provide energy for process compression as well as extra steam. Catalytic reduction can achieve greater NO x reduction than extended absorption. However, high fuel ...
