With the steady progress of policies related to the 2030 Carbon peak and 2060 Carbon neutrality targets in China, the demand for Carbon Capture, Utilization and Storage (CCUS) technologies of various Carbon dioxide containing gas sources in the industrial field has significantly increased. Carbon dioxide rich sources such as lime kiln gas, flue gas and fermentation gas are usually at low pressure. Our company has developed two technologies for carbon dioxide separation and recovery. Low partial pressure carbon dioxide pressure swing adsorption (PSA) recovery patented technology, can purify 8~13vol% of carbon dioxide in gas source to more than 95%, carbon dioxide yield of 70~90%. Compound organic amine absorption and separation of carbon dioxide technology, namely MEA as the main solvent, adding active amine, antioxidant and corrosion inhibitor, has high carbon dioxide absorption capacity, low regeneration energy consumption, basically eliminate oxygen degradation side reaction and equipment corrosion is very small. The purity of carbon dioxide gas can reach 99.5% by using this technology. Industrial or food grade carbon dioxide products can be obtained through further purification/liquefaction to achieve carbon capture and utilization.
