Pollutants emitted from combustion sources have been regulated by local and federal governments since the early 1960s. Specific rules vary by state and air district, but they generally apply to ...

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) ...

This standard will address the control functions associated with the selective catalytic reduction systems on fossil fired steam boilers greater than 200,000 lbs/hr and combustion turbines greater ...

The issues involved with running hot selective catalytic reduction (SCR) systems on large-frame, simple-cycle gas turbines, and with controlling emissions during start-up for fast-starting ...

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, ...

The numbers tell the story of how the addition of selective catalytic reduction (SCR) technology helped an iconic New Mexico coal-fired plant reduce its emissions, keeping the plant in operation and ...

The mechanisms of plasma enhanced selective catalytic reduction of NOx on a V₂O₅-WO₃/TiO₂-catalyst were investigated for temperatures between 100 °C and 200 ...

As pickup truck fans (particularly diesel lovers) can attest, the advent of the selective catalytic reduction control process for today's diesel is seen as a real crimp on the widespread introduction ...

MAN Energy Solutions has announced the production of a massive Cluster 5 Double Layer Selective Catalytic Reduction (SCR) converter to MITSUI E&S. The cluster comes ammonia-ready and is the largest ...
