RECLAIMING DEVICE AND METHOD, AND RECOVERY DEVICE FOR CO2 OR H2S OR BOTH

摘要

Provided are an evaporator 51 that separates, from a degraded substance, an absorbent 17 branched off and introduced, a heating section 53 which is interposed on a circulation line L 21 that circulates the absorbent 17 introduced into this evaporator 51, heats the circulating absorbent 17 to obtain gaseous recovery steam 52 containing a vaporized absorbent and C0 2 , a concentrate branch line L 22 that branches off a part of the absorbent 17 circulating through the circulation line L 21 at a bottom 51b of the evaporator 51 from the circulation line L 21 as a concentrate 54, a cooler 55 that is interposed on this concentrate branch line L 22 and cools the concentrate 54, an ionic degraded substance removal section 56 that removes an ionic degraded substance in the cooled concentrate 54, and a purified absorbent discharge line L 23 that reuses the concentrate 54 as a purified absorbent 17b from which the ionic degraded substance is removed.
