酸性ガス回収システム及びそれに用いるリクレーミング装置

Japanese Patent JP6598688

B2

There are provided an acidic gas recovery system and a reclaiming device to be used in the same, which are capable of preventing a vaporized material to be recovered during a reclaiming treatment of an acidic gas absorption liquid from entraining an impurity due to liquid entrainment and the like. An acidic gas recovery system includes a reclaiming device 40A which separates an absorption liquid from coexisting materials other than an absorbent. The device includes: a gas-liquid separator 50 that accepts introduction of the absorption liquid as a treatment target together with water and separates the absorption liquid into a non-volatile material and a vaporized material; a first discharged liquid line 55c which heats a first discharged liquid discharged from the gas-liquid separator by using a first heater 56, and then introduces the first discharged liquid into the gas-liquid separator at a position below an absorption liquid introduction port; and a second discharged liquid line 55a which mixes a second discharged liquid discharged from the gas-liquid separator with an alkaline agent in a mixing tank 60, and then introduces the mixture into the gas-liquid separator at a position below a discharged liquid introduction port of the first discharged liquid line.
