摘要： A CO2 recovery system includes an absorption tower and a regeneration tower. A CO2 rich solution is produced in the absorption tower by absorbing CO2 from a CO2-containing gas. The CO2 rich solution is conveyed to the regeneration tower where a lean solution is produced from the rich solution by removing CO2. A regeneration heater heats the lean solution that accumulates near a bottom portion of the regeneration tower with saturated steam thereby producing steam condensate from the saturated steam. A steam-condensate heat exchanger heats the rich solution conveyed from the absorption tower to the regeneration tower with the steam condensate.

摘要： An apparatus for CO2 recovery which comprises: an absorption column (1003) in which a CO2-containing discharge gas (1001A) and a CO2-absorbing liquid (1002) are countercurrently contacted with each other to remove the CO2; and a regeneration column (1005) in which a rich solution (1004) containing the CO2 absorbed therein is regenerated. In the apparatus, a lean solution (1006) from which CO2 has been removed in the regeneration column (1005) is reutilized in the absorption column (1003). The absorption column (1003) has a CO2 absorption part (1010) in which the CO2 contained in the discharge gas (1001A) is recovered. The CO2-absorbing liquid (1002) which has absorbed CO2 is discharged outside from the rich side of the CO2 absorption part (1010), cooled, and then supplied to that part of the absorption column (1003) which is located on the lean side of the position where the CO2-absorbing liquid (1002) has been discharged.

摘要： A CO2 recovery system includes an absorption tower that receives CO2-containing gas and CO2-absorbing solution, and causes the CO2-containing gas to come in contact with the CO2-absorbing solution to produce CO2 rich solution, and a regeneration tower that receives the rich solution and produces lean solution from the rich solution by removing CO2 from the rich solution. A heating member is provided in the regeneration tower. The heating member heats the rich solution in the regeneration tower with steam generated when regenerating the rich solution in the regeneration tower.

摘要： A CO2 recovery system includes an absorption tower and a regeneration tower. CO2 rich solution is produced in the absorption tower by absorbing CO2, from CO2-containing gas. The CO2 rich solution is conveyed to the regeneration tower where lean solution is produced from the rich solution by removing CO2. A reclaimer heats the lean solution that is produced in the regeneration tower to produce a condensed waste-product from the lean solution by condensing a depleted material contained in the lean solution, and removes the condensed waste-product. A cooler cools the condensed waste-product.

摘要： An absorbing solution according to the present invention is an absorbing solution that absorbs CO 2 or H 2 S in gas or both of CO 2 and H 2 S. The absorbing solution is formed by adding desirably 1 to 20 weight percent of tertiary monoamine to a secondary-amine composite absorbent such as a mixture of secondary monoamine and secondary diamine. Consequently, it is possible to control degradation in absorbing solution amine due to oxygen or the like in gas. As a result, it is possible to realize a reduction in an absorption loss, prevention of malfunction, and a reduction in cost. This absorbing solution is suitably used in an apparatus for removing CO 2 or H 2 S or both of CO 2 and H 2 S.
