Abstract

1445228 Sulphur dioxide removal from waste gases; calcium sulphate H HOLTER 26 April 1974 [10 May 1973 1 June 1973 18 Sept 1973 9 Oct 1973] 18262/74 Heading C1A Sulphur dioxide is removed from flue gas and other waste gases by contacting the gas with a circulating washing liquid containing calcium carbonate and/or calcium hydroxide and water and from which calcium sulphate and any further difficultly soluble and/or insoluble materials are removed, characterized in that calcium oxide and chloride ions are added to the washing liquid. Solid material, mainly calcium sulphate, deposited from the circulating liquid may be heated to form a gypsiferous mixture to which filling agents (e.g. fly ash) and/or binding agents (e.g. cement) may be added to form structural materials (e.g. bricks).
