摘要
Abstract
Natural gas steam reforming,as one of the most important hydrogen production processes,requires a significant amount of natural gas consumption.By optimizing the reforming process,it is possible to effectively reduce natural gas consumption.Using the chemical simulation software PROII,the conversion and shift reaction processes in the hydrogen production process from natural gas steam reforming were simulated.The error of the simulated value and the measured value of residual methane dry basis content(amount-of-substance fraction)is less than 1.5%,indicating that the simulation model is reliable and effective.Sensitivity analysis of the operating parameters in the conversion and shift reaction processes was also conducted based on this simulation model.The results show that when the water-carbon ratio(mole ratio)is 3.0,the outlet temperature of the conversion furnace is 820℃,and the outlet pressure is 1.2 MPa,the methane conversion rate of natural gas is higher(about 87%),and the fuel consumption is lower(about 70 m3/h).This is the optimal reforming condition and can be used as important process control indicators for actual production process.关键词
