Coal has performed an important role as the primary energy source since the industrial era in the eighteenth century. Recently, the importance of coal has been growing in the world. In fact, IEO2010 reports that energy consumption of coal is growing from 132 quadrillion Btu to 206 in 2035. The combustion of coal emits CO2, which drives green house effects in the world. Therefore, CO2 capture process has been paid more attention in the energy production sectors, especially coal combustion and gasification field.

In the energy production sectors, integrated coal gasification combined cycle power plant (IGCC) has been attracted more attention for improved electric generation efficiency compared to conventional power plants. In this plant, CO/CO2/H2 mixtures are produced by gasification/reforming and water gas shift reaction. Then, these gases are fed into gas turbines for power generation.

Although IGCC can achieve higher power generation efficiency than conventional power plants, CO2 capture process reduces this efficiency. This is because CO2 separation from gas mixtures requires huge amount of energy.

To overcome this problem, in this study, we analyzed the pre-combustion 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.
