Wet Scrubbers are the pollution control equipment that helps in controlling the pollution by reducing the concentration of pollutants such as Sulfur dioxide (SO2) and ash content in exhaust flue gases.
As the pollution norms are getting stringent and the government is making sure that pollution laws are being implemented, many industries are coming up with various solutions and strategies for reducing the pollution and its management. One such solution is using pollution control equipment such as Wet Scrubbers.

As the pollution norms are getting stringent and the government is making sure that pollution laws are being implemented, many industries are coming up with various solutions and strategies for reducing the pollution and its management. One such solution is using pollution control equipment such as Wet Scrubbers.
Industries or power plants generally have boilers or furnaces installed in their
processes where combustion of fuel is taking place. Combustion of fuel
generates flue gases that contain a large amount of heat which is
transferred to water to convert into steam. These fuels generally
contain carbon, sulfur, hydrogen, oxygen and on combustion with air,
they form flue gases containing Sulfur dioxide (SO2), Carbon dioxide (CO2), Ash, Water vapor (H2O). Out of these SO2 and
Ash are the main pollutants that are responsible for Air pollution and
must be treated before the flue gases are vented out of the combustion
chamber.
Wet Scrubbers are the pollutant treatment equipment in which flue gases containing Sulfur Dioxide (SO2)
and Ash are allowed to bring in contact with the water by either
allowing the parallel flow or counter flow. Before allowing the contact
between flue gases and water, water is dosed with Calcium Carbonate
(CaCO3). In water SO2 creates an acidic environment and addition of CaCO3
creates alkalinity in water which negates the acidic nature of water.
The tower is filled with the random packing that allows the effective
area of contact between the flue gases and water thereby increasing the
residence time. An increase in residence time helps in increasing the
transfer of SO2 and ash from flue gases to water until they get in equilibrium before the cross each other.
