چکیده انگلیسی
To develop the new integrated gasification combined cycle (IGCC) power plants with CO2 capture, first the integrated intermittent chemical looping air separation (IICLAS) unit is added to improve the coal gasification and carries out the oxy-fuel combustion, second the CO2 compression and sequestration (CCS) unit is added to achieve deep reductions in emissions of CO2 to the atmosphere. Compared to the conventional cryogenic air separation (CAS) unit, the IICLAS unit continuously produces the high-purity oxygen without the solid looping cycles and it also generates the additional electricity by virtue of the heating jacket for the oxy-fuel combustion of methane (OCM) and the waste heat recovery mechanism. A few comparisons show that the IICLAS-based IGCCÂ +Â CCS power system (Design 2) can effectively increase 12.2% of the gross power compared to the CAS-based IGCCÂ +Â CCS power system (Design 1). For the dual IICLAS-based IGCCÂ +Â CCS power system (Design 3), the OCM units are removed and the flue gas is split to reduce the circulated steam/water. Finally, Design 3 can ensure the lowest oxygen supply rate by 50.67Â kg/s, the highest net efficiency by 40.25%, and the largest KCC factor by 0.58.
