乙醇含量超标原因及改进措施

Reasons for ethanol content overproof and retrofit measures

通过对甲醇精馏常压塔压差高影响生产负荷以及产品质量的问题,深入进行了分析和研究,提出改进措施,最终实现了精馏装置的高负荷运行,保证了产品质量,降低了装置蒸汽消耗。

High pressure difference of methanol distillation atmospheric column has influence on production load and product quality. By deeply analysis and study on these problems, retrofit measures are proposed. High load production of distillation plant is achieved, product quality is promised and steam consumption is decreased.
