Summary:Amine absorption processes are widely used in the industry to purify refinery gases, process gases or natural gas. Recently, amine absorption has also been considered for CO removal from flue gases. It has a number of advantages, but there is one major disadvantage - high energy consumption. This can be reduced by using an appropriate sorbent. From a group of several dozen solutions, three amine sorbents were selected based on primary, tertiary and sterically hindered amines. The solutions were used to test CO absorption capacity, absorption kinetics and heat of CO absorption. Additional tests were performed on the actual absorber-desorber system to indicate the most appropriate sorbent for capturing CO from flue gases.
