watermanaustralia.com Before they are released into the atmosphere, industrial exhaust gases are cleaned by scrubbers, which are air pollution control systems. They are frequently employed in industrial operations that release gases including sulphur dioxide, nitrogen oxides, and particulate matter, all of which are dangerous to the environment and to people's health. The most common kind of scrubbers are known as wet scrubbers, and they function by spraying a liquid solution over the exhaust gas stream, which subsequently traps and removes the pollutants from the gas.
watermanaustralia.com Scrubbers are utilised in many different industries, including as metal processing, chemical manufacture, and power generating etc.. They can aid in lowering emissions of pollutants including particulate matter and sulfur dioxide, which can both contribute to acid rain and cause respiratory issues.

watermanaustralia.com 1. Flue Gas Desulfurization (FGD) Scrubber, Desulfurization of Flue Gas Equipment's
FGD, commonly known as a wet scrubber, is a form of air pollution management device used to remove sulphur dioxide (SO2) from industrial process and power plant exhaust flue gases. Sulfur dioxide is a hazardous gas produced by the combustion of fossil fuels such as coal and oil, and it contributes to acid rain and other environmental issues. The FGD process involves spraying a liquid solution, usually a mixture of water and limestone or lime, into the flue gas stream. The solution reacts with the sulfur dioxide in the gas stream, forming a solid compound that can be collected and disposed of.
The FGD equipment typically consists of a scrubbing tower or vessel, a recirculation system for the liquid solution, and a solid handling system for the by-products. watermanaustralia.com
watermanaustralia.com There are several types of Each system has its own FGD systems, including unique advantages and disadvantages, depending on the specific application and operating conditions. spray tower, venturi scrubber, and packed bed scrubber systems.
One of the main advantages of FGD equipment is its effectiveness in removing sulfur dioxide from flue gas streams. With proper design and operation, FGD systems can remove up to 99% of the sulfur dioxide emissions from power plants and industrial processes. This can significantly reduce the environmental impact of these operations and help to meet regulatory requirements.
[email protected] The solid compounds This can provide a cost formed during the FGD savings and process, such as gypsum and calcium sulfite, can environmental benefit for the facility. be sold or reused in other applications, such as cement manufacturing and agriculture.
watermanaustralia.com Packed Tower Gas Scrubber:
• Tower Gas in Packing In scrubbers, a tower of packing material is used to increase the surface area of the gas-liquid contact region. • As the gas stream moves through the tower, the liquid stream that removes contaminants interacts with it. • By entering the tower through the intake near the bottom and moving through the support plate and packed bed in the opposite direction as the scrubbing liquid flow, gas eliminates contaminants. • After passing through the packed bed, the cleaned gas continues its journey towards the top of the tower through a mist eliminator section. In this case, any entrained liquid is removed before the pure air is released through the exit. • These types of scrubbers work best when the gases being handled are clear of particles, as these have a tendency to clog the packing.

3. WET Electrostatic Precipitators: watermanaustralia.com
An electrostatic precipitator known as a WET Electrostatic Precipitator (ESP) removes contaminants from gas streams by using a liquid medium. A high voltage electrode is used to charge the pollutants in the gas stream, which attracts them to the liquid medium. In an ESP chamber, contaminated air is drawn in and ionised by electron emitting electrodes. The electron field charges the suspended particles, which then move to a collection plate. Rapping or beating the collection plates with rappers periodically removes accumulated particle matter from the plates. Heavy particles fall to the ESP's base where they are collected in hoppers for disposal.
