Abstract

CO2 emission reduction has become the consensus of various industries in China. CO2 capture, utilization and storage, as an important means for CO2 emission reduction, is one of the necessary paths to achieve carbon neutrality. Combined with the CO2 emission of a chemical industry company in the region of East China, this paper introduces the recovery methods, processes and costs of different CO2 emission sources, and analyzes the CO2 emission reduction path for the company. Results showed that the process complexity and unit cost of CO2 capture decreased with the increase of concentration of CO2 emission sources, the carbon recovery cost per ton of high concentration CO2 emission source is only about 1/3 of that of low concentration CO2 emission source, which has significant economic benefits on the premise of downstream absorption pathway. Therefore, priority should be given to the recovery of high concentration CO2 emission sources. The carbon recovery economy of low concentration CO2 emission sources is poor, so priority should be given to using new energy to reduce their emissions, and coupling new energy technologies in the recovery process to reduce the recovery cost.
