Improved fuel economy. More power. Less active regeneration. And above all, miniscule amounts of pollutants from the tailpipe. These are but some of the metrics Mack Trucks is establishing through an ...

Selective Catalytic Reduction (SCR) is an after treatment technology that uses a urea based diesel exhaust fluid (DEF) and a catalytic converter to significantly reduce oxides of nitrogen (NOx) ...

Selective catalytic reduction (SCR) projects often focus on the final NO x emissions levels achieved, but a successful project is about much more than that. Facility owners must consider the complete ...

Modern diesel engines are engineering marvels of power and efficiency — but they also come with a complex web of emissions ...

With the increased popularity of biomass and other renewable fuels in the generation portfolio, new emissions control challenges are emerging, especially for selective catalytic reduction (SCR) ...

An off-road machine’s selective catalytic reduction (SCR) system converts toxic nitrogen oxides in a diesel’s exhaust—nitrogen monoxide (NO) and nitrogen dioxide (NO2)—into harmless nitrogen, water, ...

Power plant owners and operators have a range of systems available to help reduce pollutants at their facilities, depending on a number of factors. And industry experts agree—there is no “one size ...
