Gas Purification from SO 2 in Thermal Power Plants
Solid fuel combustion in thermal power plants, which use sulfur‐rich fuels, poses the problem of SO 2 removal from waste gases. In addition, purification of huge amounts of gas with low SO 2 concentration is necessary. A maximum absorption rate could decrease the size of required big apparatuses. Ga...
