    limestone is crushed by a grinding machine and blended with water to form an alkaline slurry. The resulting solution is then brought into contact with flue gas to absorb SO 2 by a vaporliquid reaction [6]. At this point, the crystallization of gypsum occurs in the liquid phase in the lower part of the scrubber owing to a solidliquid reaction [7]. After this reaction, the wastewater is ...
