＂3 ＋ 1＂ tower of methanol distillation process optimization is analysed

Introduces the Shell pulverized coal gasification and methanol synthesis process of ＂3 ＋ 1＂ tower distillation process system pro- cess and actual operation. To appear in the operation of the device is not set through high temperature, field empty with alcohol problems such as serious analysis, take effective measures and technical reconstruction operation optimization adjustment. To solve the ＂3 ＋ 1＂ tower distillation process the problems existing in the system of the high load and distillation system the problem of high consumption in summer, not only ensure the safe and stable operation of unit, at the same time satisfy the economic operation.
