Calculation of thermalefficiency for pre-combustion CCSbase on SR method for hydrogen production

Carbon dioxide Capture and Storage (CCS) is a solution for extra emission greenhouse gases to atmosphere. Post combustion, Oxy combustion and Pre combustion are tree approach in CCS. In pre combustion, hydrogen is separated from synthesis gas stream. Therefore efficiency of hydrogen production is very important. Hydrogen used as fuel and Steam Reforming is main method for hydrogen production. In this work thermal efficiency of Pre combustion process based on SR hydrogen production determined briefly. Aspen plus Simulation results are considered for discussion about thermal efficiency
