摘　　要：借助Aspen Plus软件,对天然气非催化部分氧化制合成气工艺流程进行模拟分析,流程模拟所用的物性参数及相关反应数据源自于实际的天然气转化装置,模拟结果与实际运行装置的操作数据大致吻合,表明模拟结果真实可靠。通过调整反应温度、n(H_(2)O)/n(CH_(4))、n(O_(2))/n(CH_(4))等工艺参数,考察对转化炉出口气体组成的影响。结果表明,增加转化炉反应温度、n(H_(2)O)/n(CH_(4))、n(O_(2))/n(CH_(4)),均可有效降低出口气体中的CH_(4)含量,但增大n(H_(2)O)/n(CH_(4))和n(O_(2))/n(CH_(4)),会导致出口转化气中CO_(2)含量增加,提升反应温度则有利于降低出口转化气中的CO_(2)含量。Using Aspen Plus software,the process flow of non-catalytic partial oxidation of natural gas to synthetic gas was simulated and analyzed.The physical parameters and related reaction data used in the process simulation were derived from the actual natural gas conversion device,and the simulation results were roughly consistent with the operational data of the actual operating device,indicating that the simulation results were true and reliable.By adjusting process parameters such as reaction temperature,molar ratio of H_(2)O to CH_(4),and molar ratio of O_(2)to CH_(4),the effects on the gas composition and its content at the outlet of the reformer were investigated.The results show that increasing the reaction temperature of the conversion furnace,H_(2)O/CH_(4)molar ratio,and O_(2)/CH_(4)molar ratio can effectively reduce the CH_(4)content in the outlet gas.However,increasing the molar ratios of H_(2)O to CH_(4)and O_(2)to CH_(4)lead to an increase of the CO_(2)content,and increasing the reaction temperature is beneficial for reducing the CO_(2)content in the outlet conversion gas.
