PROBLEM TO BE SOLVED: To attain an effective utilization of heat held in discharged gas from a regenerator. SOLUTION: There are provided a re-boiling unit 7 and a condenser 6. Absorbing solution of high concentration transferred from an absorbing unit 4 at the re-boiling unit 7 is evaporated by the discharging gas flowed from a regenerator 1, the evaporated vapor is transferred to a condenser 6, wherein high concentrated liquid and discharged liquid are attained through condensation at the condenser 6, the high concentrated liquid is heated at a low temperature segment of the absorbing unit 4, thereafter it is transferred to the regenerator 1, the discharged liquid is heated at a high temperature segment of the absorbing unit 4 and transferred to the regenerator 1. |
