seawater fgd
The deep-sea water flue gas desulfurization( FGD) technique is an advanced technology which filters out sulfur dioxide from the fumes emitted in coal-based powerplants As it mainly cleanse flue gases, being a chemically inactive and inert substance free from sulphur dioxide or other impurities, before their release should be stopped into the air by using seawater spraying (for air cleaning). The use of this technology involves applying seawater to the smokestack of a fumes-condensing system, where it neutralises acid gases as they embark there along with their nitrogen oxides plus others in water droplets. The seawater absorbs SO2 and other harmful components in the gas flow, including NOx (oxides of nitrogen) from combustion processes at power plants and CO2 produced as industry's waste material. This gas that has now been cleaned is discharged via a chimney. Use of seawater FGD is widespread, especially in coast eras where there are large power plants near the sea, making it economically feasible as well as ecologically sound solution to clean up air pollution.
