Carbonation of gypsum from wet flue gas desulfurization process
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 …Web
