Abstract

The CO ₂ separation process in the pre-combustion capture process was analyzed using a process simulator (PRO/II) in the steady-state. A new energy saving by self-heat recuperation (SHR) was proposed. Pre-combustion capture was applied in the integrated coal gasification cycle (IGCC) plant, which involved coal gasification and CO-shift conversion with CO ₂ separation. The energy consumption for the CO ₂ separation using SHR was decreased by two thirds. This means that the electric generation efficiency can be improved by SHR compared with conventional IGCC with a CO ₂ separation. This is an abstract of a paper presented at the 2012 AIChE Spring Meeting and 8th Global Congress on Process Safety (Houston, TX 4/1-5/2012).
