Removal of sulfur oxides from flue gases by powdered limestone
Abstract. Translated from Teploenergetika; 20: No. 1, 33-37(1973). It was concluded that the method described for removing sulfur dioxide from flue gases of high-sulfur-content fuels is the simplest method since it does not require any additional equipment for preparing the absorbent, for implementing the absorption process and for removing wastes formed at the power stations.
