There is an increasing interest in post-combustion CO2 capture connected with climate change and further use of captured CO2 in enhanced oil and gas recovery and as a feed to produce such products as methanol, dimethylether and others, use in hot dry rock technologies etc. The currently used post-combustion method with monoethanolamine (MEA) absorption without stream split has two shortcomings: significant steam consumption to regenerate amine solution and relatively high cost of heat exchange equipment of absorption unit or Heat Exchange Network of Absorption Unit (HEN AU). The variation of temperature differences on rich/lean heat exchanger was considered and its influence on heat supply, cost of HEN AU and cold utility consumption was searched. The high effective plate heat exchangers are proposed as components of HEN AU to decrease its cost. The possibility of flue gas stream heat integration for heat supply to the desorber was searched too.
