【摘要】 针对以天然气为原料气的甲醇装置中换热式纯氧两段转化工艺,为扩大甲醇生产能力,在不改变空分系统的基础上讨论了改造之后的工艺,根据反应方程式并结合实际运行情况,利用物料平衡、热量平衡及物质守恒原理,对物料及能量变化进行了分析,得到了合适的氢碳比和应加入的二氧化碳的量。同时对改造前后转化工艺的情况进行了比较。更多还原

【Abstract】 For the heat exchange type pure oxygen double conversion process based on natural gas feed,in order to expand the methanol production capacity,and without changing the air separation system,the process after revamp is discussed.Based on the reaction equation and actual operation,the material and energy variation is analyzed by using the material balance heat balance and law of conservation of mass,and the appropriate carbon/hydrogen ratio and the amount of carbon dioxide to be charged is obtained.Simultaneously,the process before revamp is compared with that after revamp.更多还原
