To retrofit the traditional integrated gasification combined cycle (IGCC) plants, four plant designs using different combinations of the chemical-looping air separation (CLAS), calcium-looping (CaL), and syngas chemical-looping (SCL) are presented, where the modeling of calcium/chemical looping cycles in fast fluidized-bed and moving-bed reactors have been validated by experimental data. The IGCC polygeneration plants (Designs 1 and 2) and the IGCC power plants (Designs 3 and 4) are developed in an integration simulation platform, and their performances in terms of gross power efficiency (GPE), net thermal efficiency (NTE), carbon emission rate (CER) and water recycling rate (WRR) are evaluated. The comparison results show that (i) Design 1 possesses high thermal efficiency and low water consumption since the SCL cycle can improve NTE and increase WRR by producing the high-purity hydrogen and recovering water from exhaust gases, and (ii) Design 4 possesses high power efficiency and low CO₂ emissions since a combination of Rankine and Brayton cycles is integrated to increase GPE and CO₂-rich gas is partially recycled in the CLAS cycle to decrease CER.

为了对传统的整体气化联合循环（IGCC）厂进行改造，提出了四种使用化学回路空气分离（CLAS），钙回路（CaL）和合成气化学回路（SCL）的不同组合的工厂设计。实验数据验证了快速流化床和移动床反应器中钙/化学循环循环的建模。IGCC多联产发电厂（设计1和2）和IGCC发电厂（设计3和4）是在集成仿真平台中开发的，它们在总功率效率（GPE），净热效率（NTE），碳排放方面的性能评估排放率（CER）和水循环利用率（WRR）。_2级因为朗肯和布雷顿循环的组合的排放进行积分以增加GPE和CO ₂富气中的CLAS循环部分循环以降低CER。
