Title:
CARBON DIOXIDE AND SULFUR OXIDE CAPTURE AND CARBON RESOURCE CONVERSION SYSTEM FOR INTEGRATED GASIFICATION COMBINED CYCLE
Document Type and Number:
WIPO Patent Application WO/2023/210873
Kind Code:
A1
Abstract:
A carbon dioxide and sulfur oxide capture and carbon resource conversion system for an integrated gasification combined cycle, of the present invention, uses a basic alkali mixture solution so as to capture carbon dioxide contained in exhaust gas and converts same into a carbon resource, and thus reduces carbon dioxide while solving the problems of poor process operation efficiency and economic feasibility, and, simultaneously, can prepare sodium carbonate or sodium bicarbonate by using the captured carbon dioxide. In addition, the present invention uses sodium carbonate or sodium bicarbonate, prepared from the capture carbon dioxide, as a desulfurizing agent for capturing sulfur oxides in the exhaust gas discharged from an integrated gasification combined cycle power plant, so as to capture carbon dioxide and sulfur oxides simultaneously through a simple system, and thus it is unnecessary to provide additional flue-gas desulfurization equipment. Therefore, provision space of exhaust gas treatment equipment for removing pollutants, which are contained in gas flowing into carbon capture equipment, is minimized and process costs can be reduced.
