Absorption tower having absorption separator

An absorption tower for dissolving an object gas in a lean absorbent liquid to generate and supply a rich absorbent liquid, the absorption tower comprising:

• an absorption tower housing;
• a lean absorbent liquid supplier, disposed inside at an upper portion of the absorption tower housing, and supplying the lean absorbent liquid into the absorption tower housing;
• an absorption tower rectifier disposed under the lean absorbent liquid supplier in the absorption tower housing, the absorption tower rectifier rectifying flow of the lean absorbent liquid supplied downwardly in the absorption tower housing and dissolving the object gas in the lean absorbent liquid to generate the rich absorbent liquid;
• an absorbent liquid chamber disposed below the absorption tower rectifier in the absorption tower housing and temporarily storing the rich absorbent liquid therein;
• and
• an absorption separator disposed between the absorption tower rectifier and the absorbent liquid chamber in and cross the absorption tower housing,
• wherein the object gas is supplied into the absorbent liquid chamber and flows upwardly to the absorption tower rectifier through the absorption separator, and
• wherein the absorption separator separates an outlet through which the object gas flows out from the absorbent liquid chamber from an inlet through which the rich absorbent liquid flows into the absorbent liquid chamber such that the object gas does not meet the rich absorbent liquid in the absorption separator.
