Abstract

The pre-combustion capture is widely applied in hydrogen production which consists of gasification/reform process with H2/CO2 separation process, and the H2/CO2 separation process is applied to integrated coal gasification combined cycle power plant (IGCC). IGCC can achieve higher power generation efficiency than conventional power plant. However, CO2 capture process reduces this efficiency. This is because CO2 separation from gas mixtures requires huge amount of energy. In this study, we analyzed the precombustion process combined CO2 separation process based on self-heat recuperation technology (SHR). The electric generation efficiency can be improved by SHR compared with conventional IGCC.
