Abstract

Sulphur dioxide in hot flue gas is absorbed by spray drying in the flue gas of a suspension containing calcium hydroxide. Removal of fly ash from the flue gas is dispensed with prior to the absorption-and-spray-drying process, and the powder resulting from the process comprising the fly ash and partly reacted calcium hydroxide is fed back. The conditions are adjusted such that the flue gas has a temperature after the process lying 8-40 degrees centigrade above its dew point. The method provides a particularly good utilisation of the calcium hydroxide used as base material and the neutralising capability of the fly ash, and problems with sedimentation of the absorption medium prior to its atomising are avoided.
