Co2 Emission Reduction Path and Cost Analysis for a Chemical Industry Company in East China Based on Ccus

CO 2 emission reduction has become the consensus of various industries in China. CO 2 capture, utilization and storage, as an important means for CO 2 emission reduction, is one of the necessary paths to achieve carbon neutrality. Combined with the CO 2 emission of a chemical industry company in the region of East China, this paper introduces the recovery methods, processes and costs of different CO 2 emission sources, and analyzes the CO 2 emission reduction path for the company. Results showed that the process complexity and unit cost of CO 2 capture decreased with the increase of concentration of CO 2 emission sources, the carbon recovery cost per ton of high concentration CO 2 emission source is only about 1/3 of that of low concentration CO 2 emission source, which has significant recovery economic benefit on the premise of downstream absorption pathway. Therefore, priority should be given to the recovery of high concentration CO 2 emission sources. The carbon recovery economy of low concentration CO 2 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
