Patent ID: 8137441

Claim:
A CO 2 recovery system comprising: an absorption tower suitable for receiving a CO 2 -containing gas and a CO 2 -absorbing solution, and the absorption tower suitable for causing the CO 2 -containing gas to come in contact with the CO 2 -absorbing solution to produce a CO 2 rich solution, and a regeneration tower suitable for receiving the CO 2 rich solution and suitable for producing a lean solution from the CO 2 rich solution by removing CO 2 from the CO 2 rich solution, a reclaimer suitable for receiving a part of lean solution, produced in the regeneration tower and removed via an extracting line when a first valve is open, wherein the reclaimer further comprises an external water source suitable for supplying water to the reclaimer when a second valve is open, a heating means suitable for heating the part of lean solution to obtain a heated condensed waste-product from the part of lean solution and to obtain a vaporized CO 2 absorbing solution, a means for feeding the vaporized CO 2 absorbing solution via a vaporized CO 2 -absorbing solution supply line to a lower portion of the regeneration tower when a third valve is open, and a means for conveying a part of heated condensed waste-product from the whole heated condensed waste-product when the third valve is closed but a fourth valve is open, and wherein the first valve is arranged on the extracting line and below the reclaimer, the second valve is arranged on the water supply line and below the reclaimer, the third valve is arranged on the vaporized CO 2 -absorbing solution supply line and above the reclaimer, and the fourth valve is arranged below the reclaimer; a cooling unit suitable for receiving the part of heated condensed waste-product from the reclaimer to be cooled to the specified temperature every time, the cooling unit suitable for cooling the part of heated condensed waste-product by coolant water that is poured into the cooling unit via a coolant water supply line when the fourth valve and a fifth valve are closed, wherein the cooling unit further comprises a means for conveying a part of cooled condensed waste-product when the fourth valve is closed but the fifth valve is open, and wherein the fifth valve is arranged below the cooling unit; and a receiving tank suitable for receiving the part of condensed waste-product cooled by the cooling unit.
