Research on Carbon Dioxide Capture Technology and Suitable Scenarios

Abstract

The development of industry has brought a large amount of CO2 emissions. In the process of achieving the goal of carbon peak and carbon neutralization, carbon dioxide capture, utilization and storage (CCUS) technology is an indispensable key technology. The carbon capture method with high technology maturity at this stage and great development potential in the future is post combustion carbon capture technology, mainly including solvent absorption, adsorption, membrane method and cryogenic distillation. The development and industrial application of the four most commonly used carbon capture methods were briefly introduced, and the industrial applicability of several methods was analyzed, especially the chemical absorption method and physical adsorption method, which are most widely used in large-scale carbon capture projects currently running. Chemical absorption method, adsorption method and membrane carbon capture technology have great development potential in the future, which can quickly promote the achievement of the goal of double carbon and help the near-zero emission of carbon.
