Abstract

The removal of SO3, sulphuric acid and sulphuric acid mists from flue gases of wet desulphurisation plants in the combustion of sulphur-rich coals is improved by spraying at least one separator layer of a demister system with a quantity of caustic soda, soda, aqueous ammonia or mixtures thereof, which is in excess relative to the total residual quantity of sulphuric acid in the gas. About 95% of the residual sulphuric acid in the pure gas can thus be removed. The alkali solutions flowing back into the reaction vessel do not interfere with the remainder of the desulphurisation process and the formation of large gypsum crystals.
