In this paper, a gas-fired combined cycle power plant subjected to a pre-combustion CO2\ncapture method has been analysed under different design conditions and different heat integration\noptions. The power plant configuration includes the chemical looping reforming (CLR) of natural\ngas (NG), water gas shift (WGS) process, CO2 capture and compression, and a hydrogen fuelled\ncombined cycle to produce power. The process is denoted as a CLR-CC process. One of the main\nparameters that affects the performance of the process is the pressure for the CLR. The process is\nanalysed at different design pressures for the CLR, i.e., 5, 10, 15, 18, 25 and 30 bar. It is observed that\nthe net electrical efficiency increases with an increase in the design pressure in the CLR. Secondly,\nthe type of steam generated from the cooling of process streams also effects the net electrical efficiency\nof the process. Out of the five different cases including the base case presented in this study, it is\nobserved that the net electrical efficiency of CLR-CCs can be improved to 46.5% (lower heating value\nof NG basis) by producing high-pressure steam through heat recovery from the pre-combustion\nprocess streams and sending it to the Heat Recovery Steam Generator in the power plant
