Abstract The goal of this study is to assess the technical and economic feasibility of producing marketable products, namely fertilizer-grade ammonium sulfate and calcium carbonate, from gypsum produced as part of limelimestone flue gas desulfurization FGD processes. Millions of tons of FGD-gypsum by-product will be produced in this decade.
