Introduction to the wet desulfurization process of limestone gypsum:

Steel plants, cement plants, kilns, and boilers generally use the limestone gypsum wet desulfurization process. The structure of the limestone gypsum flue gas desulfurization system consists of a limestone slurry preparation system, an absorption system, a flue gas reheating system, a gypsum dehydration system, and a wastewater treatment system.
