摘　　要：文章主要介绍我公司精馏塔热源利用问题,目前甲醇装置精馏工段预塔再沸器和加压塔再沸器的热源为低压蒸汽,存在能源消耗浪费问题,为了降低甲醇的能耗,优化工艺,提高甲醇的盈利能力,公司决定对甲醇精馏热源进行改造,用转化气替代低压蒸汽作为精馏热源。This paper mainly introduces the heat source utilization problem of our company’s distillation column.At present,the heat source of the pre-tower reboiler and pressurized tower reboiler of methanol distillation plant is low-pressure steam,which has the problem of energy consumption and waste,in order to reduce the energy consumption of methanol,optimize the process and improve the profitability of methanol,our company decided to reform the heat source of methanol distillation and replace low-pressure steam with conversion gas as the heat source of distillation.

关 键 词：甲醇精馏 热源 再沸器 低压蒸汽 转化气
