The wet flue gas desulphurization has been the most widely used in the coal-fired power plants because of high SO 2 removal efficiency, reliability and low utility consumption. In this paper, laboratory studies on the removal of SO 2 from gas mixtures with a novel wet-type PCF device (Chinese LOGO) were reported, CaCO 3-in-water suspension used as absorbent.
The combustion of sulphur containing fossil fuels requires downstream flue gas cleaning, which is often accomplished by wet processes. This is where the raw flue gas is cleaned in an absorption wash tower where the sulphur dioxide reacts with an aqueous slurry of limestone to form gypsum.
