摘要
对甲醛脱醇塔的现状进行了概述，通过优化生产工艺降低脱醇塔进料、重新设计脱醇塔真空平衡管线、脱醇塔回流泵设置双过滤器，消除了脱醇系统频繁堵塞的情况，降低系统清理时间，提高了脱醇塔效率，精甲醛中甲醇质量分数由1.8%以上降至1%以下，稳定了生产。
Abstract
The current situation of formaldehyde dealcoholization tower is summarized.Problem of frequent plugging in the dealcoholization system is solved through optimizing the production process,reducing the feed rate to the dealcoholization tower,re-designing the vacuum equalization line in the dealcoholization tower and assembling dual filters for the reflux pump of the dealcoholization tower.And the system clean-up time is also reduced,the efficiency of the dealcoholization column is improved,the methanol content in refined formaldehyde drops from 1.8% to 1% and stable production is achieved.
