Abstract

An acid gas regenerator includes a regenerator condenser that condenses moisture from entraining gas entraining a corrosive substance and acid gas discharged from a column top portion of a regenerator that regenerates acid gas absorbent. The regenerator condenser includes: a gas discharge line that discharges the entraining gas from the column top portion of the regenerator, a cooler installed on the discharge line; a gas-liquid separator that separates COgas from regenerator condensed water obtained by condensing vapor using the cooler, a reflux line that refluxes the regenerator condensed water closer to the column top portion than the rich solution introducing unit; a condensed water receiver storing the condensed water introduced by the reflux line; and a first condensed water extraction line that extracts the condensed water from a condensed water extractor of the condensed water receiver and is connected to a lean solution supply line.
