Method and apparatus for improving the separation performance of separation membrane system for recovering carbon dioxide in the combustion gas

摘要

The present invention relates to a method and an apparatus for improving the separation performance of a separation membrane system for recovering carbon dioxide in a combustion gas, including a front end gas separation unit and a rear end gas separation unit, The compressor can be operated continuously to prevent deterioration of the carbon dioxide separation efficiency of the front end gas separation unit, thereby improving separation performance of the separation membrane system.
