Over the past several decades there have been immense improvements in process chemistry, a better understanding of materials, simplified designs, and other technological enhancements. Flue-gas desulfurization (FGD) is a set of technologies used to remove sulfur dioxide (SO₂) from exhaust flue gases of fossil-fuel power plants, and from the emissions of other sulfur dioxide emitting...

Recent research has shown that removing carbon dioxide (CO₂) from the atmosphere can be done on an industrial scale that would be economically viable. The research was carried out by the Canadian company “Carbon Engineering” that built a pilot plant in Squamish. This plant removes carbon dioxide from the atmosphere and uses it to produce...

Power plants burn coal, so the smoke and fumes constitute a serious threat to the health of the people who live downwind. The federal government is now trying to decide this problem. It seems that the simplest solution is an adoption of a tighter emission standard. But in fact, it should be noted, the smokestack...

Wet air scrubbers are devices used in underground coal mines for the exhaust air treatment system of various internal combustion engines, primarily as a spark arrestor. A secondary function is to remove pollutants from the exhaust gas. Wet scrubbers are widely used in underground applications of diesel particulate matter (DPM) and other pollutant gases. Wet...

Wet air scrubbers, which use seawater or fresh water as cleaning media for sulfur dioxide, are progressively used by shipping companies to comply with emissions regulations. Nowadays shipping emissions are likely to increase significantly, alongside increasing emphasis on the sustainability and environmental impacts of the maritime transport sector. Emissions of gases and particulates to the...
