  • 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.

  • Publication number: 20230331575
    Abstract: The present invention relates to a method for preparing an inorganic compound by using recyclable resources to reduce greenhouse gas emissions and, more specifically, to a method for preparing an inorganic compound, wherein a carbonated inorganic compound can be prepared in a continuous pattern by capturing carbon dioxide generated at industrial sites, with a desulfurization byproduct, which is an industrial waste, serving as a medium, although not using a separate drying process and an additive for pH adjustment for promoting carbonation, thereby significantly reducing greenhouse gas and process costs compared with existing processes.
