Abstract

CCS (Carbon Capture and Storage) is one of the best technology for carbon dioxide reduction. MEA (Monoethanolamine) is widely used absorbent in chemical absorption. We are trying to convert carbon dioxide into calcium carbonate using MEA absorbent and industrial waste which is desulfurization gypsum. The main objective of this research is to investigate possibility of calcium carbonate salts formation by converting carbon dioxide into ionic state and using metal cation extracted from desulfurization gypsum.
