摘要： PURPOSE: To provide a system capable of still more effectively recovering carbon dioxide and other substance to be adsorbed from an oxygen-containing fed substance by using an alkanolamine based adsorbent for enhancing the grade of the fed substance. CONSTITUTION: Lean fed gas 1 is sent to a blower 2 to be compressed and this compressed lean fed gas 3 is sent to the lower part of an adsorption tower 4 from the blower 2. An adsorbent 6 is a fluid containing at least one alkanolamine species being primary or secondary alkanolamine and the lean fed gas rises against the flowing-down adsorbing material in the adsorption tower 6. As the lean fed gas rises, almost all of carbon dioxide and a small amt. of other substance to be adsorbed in the gas are adsorbed by the flowing- down adsorbent and vapor reduced in the content of carbon dioxide is collected at the upper position of the adsorption tower 6 and the adsorbent loaded with carbon dioxide containing dissolved oxygen is collected at the bottom position thereof.
