Abstract

Exergy recuperation is applied to CO₂ gas separation processes with chemical absorption for post-combustion capture. The heat of the exothermic absorption reaction in the absorber and the heat of steam condensation in the condenser of the stripper are recuperated and circulated to reuse for regeneration of solution and vaporization of water under CO₂ stripping using exergy recuperation technology. We evaluated the amount of energy consumption of the exergy recuperative process in comparison with the conventional CO₂ gas separation process by using a commercial process simulator (PRO/II, Invensys). The simulation results show that the energy consumption of the exergy recuperative CO₂ gas separation process can be decreased to 30% of that of the conventional self-heat recovery process.
