    摘要: An acid gas regenerator includes a regenerator condenser 40 that condenses moisture from entraining gas 41 entraining a corrosive substance and acid gas discharged from a column top portion of a regenerator 14 that regenerates acid gas absorbent. The regenerator condenser 40 includes: a gas discharge line that discharges the entraining gas 41 from the column top portion of the regenerator; a cooler 42 installed on the discharge line; a gas-liquid separator 43 that separates CO 2 gas from regenerator condensed water 44 obtained by condensing vapor using the cooler; a reflux line 40b that refluxes the regenerator condensed water 44 closer to the column top portion than the rich solution introducing unit 14a; a condensed water receiver 14e storing the condensed water 44 introduced by the reflux line 40b; and a first condensed water extraction line 14g-1 that extracts the condensed water 44 from a condensed water extractor 14f of the condensed water receiver 14e and is connected to a lean solution supply line 53.
