摘　　要：通过对比分析蒸汽转化法、自热重整法和非催化部分氧化法等天然气生产合成气的工艺技术,得出天然气非催化部分氧化法生产合成气装置工艺流程和设备结构简单,投资低,操作可靠,合成气中H_(2)/CO体积分数比接近于2,是乙二醇合成的理想原料气。介绍了某15万t/a天然气制乙二醇项目中天然气非催化部分氧化生产合成气的工艺流程,详述了转化炉、废热锅炉的设计要点和系统的控制方案及H_(2)/CO体积比调节方法。运行结果表明:天然气非催化部分氧化生产的合成气中H_(2)/CO体积分数比为1.99,比天然气消耗为368 m^(3)/[1000 m^(3)(CO+H_(2))],比氧气消耗为258 m^(3)/[1000 m^(3)(CO+H_(2))],合成气中甲烷体积分数为0.3%。By comparing and analyzing the process technologies of natural gas production into syngas,such as steam reforming,autothermal reforming and non-catalytic partial oxidation,it was concluded that the non-catalytic partial oxidation process of natural gas to produce syngas had simple process flow and equipment structure,low investment and reliable operation,and the volume ratio of H_(2)/CO in synthesis gas was close to 2,which was an ideal feed gas for glycol synthesis.The process flow of non-catalytic partial oxidation of natural gas to produce syngas in a 150000 t/a natural gas to glycol project was introduced,and the key design points of the reformer,waste heat boiler,control scheme of the system and the adjustment method of H_(2)/CO volume ratio were described.The operation results showed that the volume ratio of H_(2)/CO in syngas was 1.99,the specific consumption of natural gas was 368 m^(3)/[1000 m^(3)(CO+H_(2))],the specific consumption of oxygen was 258 m^(3)/[1000 m^(3)(CO+H_(2))],and the volume fraction of methane in syngas was 0.3%.
