Wet scrubbing is a gas scrubbing method in which contaminants are removed from the gas stream by means of using a scrubbing liquid. Wet Scrubbing is used in industrial settings such as acid plants, fertilizer plants, steel mills, asphalt plants, and large power plants and is very effective in controlling odors and preventing the emission of potentially hazardous gases.
The accumulation, transport and processing of sewage results in the generation of off gases that must be controlled and treated. These organic gases vary in make-up and concentration. Within a large metropolitan wastewater treatment (sewer) system, the chemistry and concentration of these undesirable gases will also vary within the hours of a given day. The community and surrounding areas must be protected from the toxic gases and offensive odors that are generated. The packed tower is possibly the world’s most popular solution to this problem. Packed towers are also used to scrub acid gases and react with other undesirable emissions that come from a variety of industries.
The process that these structured scrubbers go through in order to remove contaminants from the contaminated gas stream is as follows: The gas stream passes through a packed structure with a large wetted surface area. The wetted area enables close contact between the gas and the scrubbing liquor, or scrubbing chemicals, which in turn allows the scrubbing liquor to react with the pollutants in the gas stream, removing them.
