In early 2019, Power Engineering published a report on a chemistry that can significantly enhance limestone reactivity and sulfur dioxide (SO 2) removal in wet flue gas desulfurization (WFGD) systems.

A generic flow diagram of a wet-limestone scrubber is illustrated in Figure 1. The process is a classic example of an aqueous acid-base chemistry reaction applied on a large industrial scale, where ...

Limestone scrubbers deployed at natural gas power plants could help reduce carbon emissions as well as lower ocean acidification by pumping a byproduct of the scrubbing process back into the water, ...

A$400-million wet flue gas desulfurization (FGD) project now under way at the Fayette Power Project near La Grange, Texas, will remove about 97% of sulfur dioxide emissions from the plant's two units ...

WASHINGTONVILLE -- At 700 feet, the new smokestack at PPL's Montour Steam Electric Station is the tallest structure on the site, and with its completion, the 1,552-megawatt plant is one of the ...

Long-time POWER readers may remember Marmaduke Surfaceblow, a fictional character whose engineering escapades were brilliantly portrayed in hundreds of stories published within POWER magazine’s pages ...

The second of two wet limestone scrubbers was placed in operation at the Leland Olds Station near Stanton. Scrubbers are environmental controls that remove sulfur dioxide emissions resulting from ...

For such a large facility, the Brayton Point Power Station is quiet up close, but you can hear a subdued “whoosh” as they test the “scrubbers.” Two of the scrubbers, which reduce air pollution, are ...

WASHINGTONVILLE -- Up close, parts of the PPL project are giant. But hundreds of feet in the air, they don't appear that big. The gargantuan Fiberglass flues and huge duct work are part of a $600 ...

When TVA’s Bull Run Fossil Plant was erected in the mid-1960s, it could boast of having the largest boiler in the U.S., and the plant has enjoyed a long, enviable efficiency track record. Today the ...
