Abstract

2222, withdrawing the lean absorbent from the regenerator (30) and introduction of the lean absorbent into the absorber (16), where the flow of lean absorbent is split in two, a first flow which is introduced at the top of an absorbent packing (17) in the absorber (16), and a second flow which is cooled against a heat fluid received from the district heating plant an returned thereto, and where the thus cooled absorbent is introduced at the top of a cooler packing (21) at the top of the absorber for cooling and drying of the lean flue gas before being reheated against incoming compressed flue gas, and thereafter expanded and released into the surrounding, and a plant for performing the method are described.

Abstract

2, where a water recirculation pipe (16) is connected to the bottom of the direct contact cooler (15) for withdrawal of used cooling water and connected to the top of the direct contact cooler(15) reintroduction of the cooling water at the top of the direct contact cooler, wherein a heat exchanger (17) connected to water recycle pipes (70, 70′) for delivery and withdrawal, respectively, of cooling water to the heat exchanger, is provided in the recirculation pipe (16) for cooling the circulating direct contact cooler cooling water in pipe (16).
