Abstract

A lean absorbent liquid supplier, disposed inside at an upper portion in the absorption tower housing, supplies a lean absorbent liquid into the housing. An absorption tower rectifier, disposed under the lean absorbent liquid supplier in the absorption tower housing, rectifies flow of the lean absorbent liquid supplied downwardly in the absorption tower housing, and dissolves an object gas in the lean absorbent liquid to generate a rich absorbent liquid. An absorbent liquid chamber, disposed below the absorption tower rectifier in the absorption tower housing temporarily stores the rich absorbent liquid therein. An absorption separator is disposed between the absorption tower rectifier and the absorbent liquid chamber in the absorption tower housing. The object gas is supplied to the absorbent liquid chamber.

First claim

What is claimed is:

1. 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.

2. The absorption tower of claim 1 , wherein the absorption separator comprises:
a first mounting plate disposed across the absorption tower housing between the absorption tower rectifier and the absorbent liquid chamber, and having at least one first gas flow hole;
a first body mounted on an upper surface of the first mounting plate, the first body having a hollow pillar shape and having an upper surface blocked by a first roof;
at least one first gas bypass port formed at a side surface of the first body such that an interior of the first body fluidly communicates with an exterior of the first body; and
a first liquid supplying pipe extending downwardly from the first mounting plate and supplying the rich absorbent liquid into the absorbent liquid chamber,
wherein an interior of the absorption tower housing under the first mounting plate fluidly communicates with the interior of the first body through the at least one first gas flow hole.

3. The absorption tower of claim 2 , wherein the first gas bypass port is formed above the first mounting plate at a predetermined height.

4. The absorption tower of claim 1 , further comprising:
a treated gas outlet, from which a target gas is removed to an exterior of the absorption tower housing, formed at an upper end portion of the absorption tower housing to discharge a treated gas, and
an absorption tower outlet formed at a lower end portion of the absorption tower housing to supply the rich absorbent liquid to a regeneration tower.

5. The absorption tower of claim 1 , wherein the absorption tower housing includes a plate mounted under the lean absorbent liquid supplier and having at least one penetration hole.

6. 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 absorbent liquid chamber formed in a lower portion of the absorption tower housing and temporarily storing the rich absorbent liquid therein; and
an absorption separator disposed between the lean absorbent liquid supplier and the absorbent liquid chamber in and cross the absorption tower housing,
wherein the lean absorbent liquid supplied into the absorption tower housing absorbs the object gas and is changed into the rich absorbent liquid as flowing downwardly, and the rich absorbent liquid is supplied into the absorbent liquid chamber through the absorption separator,
the object gas is supplied into the absorbent liquid chamber, flows out from the absorbent liquid chamber through the absorption separator, and flows upwardly in the absorption tower housing, and
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.

7. The absorption tower of claim 6 , wherein the absorption separator comprises:
a first mounting plate disposed across the absorption tower housing and having at least one first gas flow hole;
a first body mounted on an upper surface of the first mounting plate, the first body having a hollow pillar shape and having an upper surface blocked by a first roof;
at least one first gas bypass port formed at a side surface of the first body such that an interior of the first body fluidly communicates with an exterior of the first body through the at least one first gas bypass port; and
a first liquid supplying pipe extending downwardly from the first mounting plate and supplying the rich absorbent liquid into the absorbent liquid chamber,
wherein the object gas flows out from the absorbent liquid chamber through the at least one first gas flow hole and the at least one first gas bypass port, and the rich absorbent liquid is supplied into the absorbent liquid chamber through the first liquid supplying pipe.

8. The absorption tower of claim 7 , wherein the at least one first gas bypass port is formed above the first mounting plate at a predetermined height.

9. The absorption tower of claim 7 , wherein the at least one first gas flow hole is at the interior of the first body and the first liquid supplying pipe is at the exterior of the first body.

10. The absorption tower of claim 7 , wherein an end of the first liquid supplying pipe extends to be close to a lower end of the absorbent liquid housing.
