Abstract

PURPOSE: To absorb and remove SO2 effectively by bringing exhaust gas contg. SO2 into contact with an aq. soln. sontg. org. sulfocarboxylateand crystal gypsum without necessity of Glauber's salt removing step, which is necessary for alkali sulfite process, and with prevention of adhesion of crystallized gypsum.
