Abstract

A process for recovering CO₂ from the boiler flue gas of a power plant by a chemical absorption method requires a large amount of steam to regenerate the spent absorbent.<BR>The recovery heat exhausted from the CO₂ recovery process and utilization of the recovered heat as a sourse of power plant feed water heating is studied. The reduction of generated power, required for the CO₂ recovery from the flue gas by the chemical absorption method is evaluated.<BR>The effectiveness of such a heat recovery process is assessed in terms of the power loss. The power loss by heat recovery is decreased to one-third compared with that in the case of no heat recovery.<BR>The reduction of power generated in a natural gas-fired power plant is evaluated to be about 56 % when new absorbents KS-1 and KS-2 are used in the CO₂ recovery process. In the case of a coal-fired power plant, the power loss amounts to about 9%.
