  • METHOD FOR PREPARING INORGANIC COMPOUND USING DESULFURIZATION GYPSUM FOR REDUCING GREENHOUSE GAS EMISSIONS
    Publication number: 20240140815
    Abstract: The present invention relates to a method for preparing an inorganic compound using desulfurization gypsum for reducing greenhouse gas emissions, and, more specifically, to a method for preparing an inorganic compound, in which calcium sulfate and calcium carbonate, which have various uses as construction materials and the like, can be prepared using, as raw material, desulfurization gypsum which, being a recycled resource, is industrial waste, and an extraction agent, and the extraction agent can be reused after separation, and thus, compared to existing processes, greenhouse gases and manufacturing costs can be remarkably reduced.
