  • Process for desulphurization of flue gas
    Patent number: 4792440
    Abstract: In a process for purification, in particular desulphurization, of flue gas from the combustion of sulphur-containing fuel in a combustion furnace, fresh, alkaline absorption agent selected among oxides and hydroxides of calcium, magnesium and the alkai metals, is added in the flue gas channel from the combustion furnace, and the formed reaction product is separated from the flue gas.By adding the absorption agent drily after adjusting the water-dewpoint of the flue gas and/or the temperature of the flue gas so that the distance between dewpoint temperature and flue gas temperature is 5.degree.-50.degree. C., preferably 10.degree.-20.degree. C., a very effective desulphurization is obtained.
