FIELD: purification of gases.
SUBSTANCE: method comprises absorbing sulfur dioxide by means of a lime suspension, crystallization, and removing slime. The gas is cooled before absorbing up to the dew point by water evaporating. The ratio of the volume of water to that of the gas should be 0.08-0.12 l/m3. The water temperature exceeds that of the dew point by 10°C of the cooled gas. The gas is absorbed by the suspension made of droplets supplied perpendicular to the gas flow.
EFFECT: enhanced quality of purification.
