Wet Scrubbers, For Sugar Industry

A wet scrubber or wet scrubber system is one type of scrubber that is used to remove harmful materials from industrial exhaust gases—known as flue gas—before they are released into the environment. It was the original type of scrubbing system and utilizes a wet substance to remove acidic gases that contribute to acid rain. When using a wet scrubber, flue gas is funneled through an area and sprayed with a wet substance. Water is used when dust and particulate matter is to be removed, but other chemicals can be added. These chemicals are chosen to specifically react with certain airborne contaminants—generally acidic gases. This process adds significant amounts of vapour to the exhaust—which causes the release of exhaust that appears as white smoke when vented.
