Common Prejudices Regarding Wet Scrubbers: Are They Holding Industry Back?

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...

How Bill Gates Aims to Decide a Problem of Greenhouse Effect?

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...

Smokestack Scrubbers: a New Component to Industrial Exhaust Systems

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...

Best Practices for Underground Coal Mines: Wet Air Scrubbers in Mining

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...

A New Perspective on the Shipping Industry: the Environmental Impacts of Exhaust Gas Scrubber Discharge

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...

Chemical and Biological Wet Air Scrubbers in Animal Barns

The current technology behind chemical and biological air scrubbing in animal barns can be optimized by careful maintenance and recalibration. European and regional air quality policy in the last decades has increased pressure on pig and poultry farmers to limit their farms’ emissions. Each air scrubbing pressure animal barn must achieve an ammonia of 70%....

What is the Function of Wet Air Scrubbers in Industrial Process?

One of the biggest challenges environmental engineers face is devising new techniques to prevent additional air pollution. The industry is a large contributor to air pollution. Scrubbers are used at coal-burning power plants, asphalt/concrete plants, and a variety of other facilities that emit sulfur dioxides, hydrogen sulfide, and gases with high water solubility. The work...

Biological Scrubbers for Waste Gas Treatment

The starting points for the design of the biological wet air scrubber were low operating costs and energy savings. Such wet air scrubber has low water and energy consumption, as the amount of washing water that is circulated is very low. The system is characterized by clever simplicity. Thus the biological wet air scrubber reduces...
