精甲醇中的杂质乙醇含量影响因素及预防措施

摘要

During crude methanol distillation,the content of ethanol is an important index of methanol dis-tillation,it has important role of methanol quality.In this paper,the influence cause of ethanol content in methanol distillation are studied,the preventive measures are probed,the source of ethanol in fine metha-nol and its reducing measures are analysised.%在粗甲醇精馏过程中，乙醇的含量是甲醇精馏的一个重要控制指标，对精甲醇的质量有至关重要的作用。本文对甲醇精馏过程中关于乙醇含量的影响因素进行研究，并探讨了相应的预防处理措施；分析了精甲醇中乙醇的来源以及降低的措施。
