| description | PROBLEM TO BE SOLVED: To reduce regeneration energy charged into a regeneration tower from the outside and to improve the energy efficiency of a COcapture system by chemical absorption by reducing the cooling waste heat of the gas cooling of exhaust gas.SOLUTION: The COcapture system by chemical absorption includes an absorber for absorbing COby a solvent and a regenerator which heats the CO-absorbed absorption liquid to discharge the CO, and also includes a gas discharge system which discharges the gas released from the absorption liquid in the regenerator to the outside, a gas compressor installed downstream of the gas discharge system, a heat exchanger installed downstream of the gas compressor and exchanging heat between the compressed gas and a rich liquid to be sent to the regenerator, a gas-liquid separator installed downstream of the heat exchanger and separating the gas and condensed water, a condensed water supply system supplying the condensed water from the gas-liquid separator to the regenerator, another gas discharge system discharging the gas containing high concentration COfrom the gas-liquid separator, and a compressor installed downstream of the gas-liquid separator in the another gas discharge system and pressurizing the gas containing high concentration CO. |
