CO2 OR H2S REMOVING SYSTEM AND METHOD OF REMOVING CO2 OR H2S

摘要

A CO 2 reducing system (10A) is constituted by a low-temperature CO 2 reducing apparatus (11-1) that includes a low-temperature absorber (1006-1) that reduces at least one of CO 2 and H 2 S by bringing flue gas (1002) including at least one of CO 2 and H 2 S into contact with a low-temperature absorbing solution (1005-1), a low-temperature regenerator (1008-1) that regenerates a low-temperature rich solution (1007-1), a low-temperature rich-solution supply line (12-1) that feeds the low-temperature rich solution (1007-1) to the low-temperature regenerator (1008-1), and a low-temperature lean-solution supply line (13-1) that feeds a low-temperature lean solution (1009-1) to the low-temperature absorber (1006-1) from the low-temperature regenerator (1008-1); and a high-temperature CO 2 reducing apparatus (11-2) that is arranged on a side at which the flue gas (1002) is discharged, and that has the same configuration as the low-temperature CO 2 reducing apparatus (11-1).
