Carbonation of gypsum from wet flue gas desulfurization

 · In this paper waste gypsum from wet flue gas desulfurization (WFGD) mixed with NH 3 ·H 2 O was applied for CO 2 absorption in the solid-liquid-gas phase system. The effects of operation temperature CO 2 flow rates and ammonia-to-gypsum ratio on carbonation process were discussed. Meanwhile a model for CO 2 absorption in the suspension of WFGD gypsum and ammonia was established.
