Mineral carbonation of flue gas desulfurization gypsum …

Highlights FGD gypsum is a promising material for CO 2 sequestration by mineral carbonation. The carbonation rate is about 95% at room temperature and atmospheric pressure. High-purity calcium carbonate (above 90%) can be obtained within 10 min Coal-fired flue gas can be directly used in the gypsum carbonation process.

convert fgd gypsum into ammonium sulphate

The authors have been developing a process which converts FGD-gypsum to ammonium sulfate fertilizer with precipitated calcium carbonate as a by-product during the conversion. Preliminary cost estimates suggest that the process is economically feasible when ammonium sulfate crystals are produced in a granular size (1.2 to 3.3 mm), instead of a powder form.
