N2 - To develop the new integrated gasification combined cycle (IGCC) with CO2 capture, the integrated intermittent chemical looping air separation (IICLAS) unit is added to improve the coal gasification and carry out the oxy-fuel combustion, and the CO2 compression and sequestration (CCS) unit is added to realize the power plant with almost zero CO2 emissions. The IICLAS unit is operated continuously without the use of the solid looping cycles. By virtue of the heat exchanger network (HEN), the IICLAS unit reduces the external energy supply and generates the additional electricity by recovering the waste heat from the high-temperature byproduct nitrogen simultaneously. Compared to the IICLAS-based power system (Design 1), the simulations show that the dual IICLAS-based power system (Design 2) reduces the oxygen consumption and also reduces the energy demand for CCS process.
