FIELD: process engineering.
SUBSTANCE: invention relates to device and method of regeneration intended for reduction of waste material amount contained in absorbent of CO2 or H2S. Proposed device comprises absorbent tank and absorbent heater. Tank is used to keep a portion of absorbent that absorbed CO2 or H2S from gas. Absorbent heater is intended for absorbent kept in said tank. Proposed device allows bleeding a portion of absorbent kept in said tank to force it in countercurrent contact with vapor. Proposed method comprises keeping a portion of absorbent with CO2 or H2S absorbed from gas. Besides, it comprises heating kept absorbent. As well as bleeding and feeding it into countercurrent contact with vapor.
EFFECT: reduced operating costs and loss of absorbent.
