Process Simulation of Shell Pulverized Coal Gasification

Based on the analysis of the process of Shell coal gasification,the process simulation model was build,and PRO II was adopted to simulate the gasification process using typical Shenhua coal.Good agreement between the operations and simulations was observed.In addition,operating conditions like pressure,temperature,coal-oxygen ratio,steam-coal ration,coal convert rate,and transform gas were simulated.From the simulation,the pressure has little influence on the coal gasification,but the composition of syngas can be manipulated by changing temperature,coal-oxygen ratio,steam-coal ration,and transform gas.
