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 ...

The process that can convert pollution into benign by-products is called selective catalytic reduction, or SCR. Until now, it has been unclear how this reaction actually occurs, and contradictions ...

Emission regulations for combustion systems have been in place for more than half a century and in the 1990’s, the Clean Air Act put a spotlight on emissions specifically from industrial boilers.

The SIP Call NO x mandate has prompted the broad application of SCR technology within most utility generating systems. Worldwide SCR experience in Japan and Europe on coal-fired units is approximately ...

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, ...

In a 2023 report, McKinsey & Company projected 35 GW of new power will be needed for data centers in the U.S. by 2030. This forecast doubled the required power consumption from data servers, up from ...

K, enables major progress in low-temperature diesel NOxemission control. Its higher fraction of Al in 8-memberedringspromotes ...

•Ammonia Inj.: The total mass flow rate of ammonia injected into the SCR. This is a function of the NOx concentration in the flue gas and the ammonia stoichiometric performance input value. •Steam for ...

Utilities with coal-fired power plants will soon have to comply with the new Mercury and Air Toxics Standards (MATS) regulation, which focuses on mercury and other hazardous pollutants. With the ...

Nitrogen Oxides (NOx) emissions are regulated not only because they are highly reactive gases, but also due to the fact they react with VOC and Sunlight to form ground level ozone and smog. The ...
