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。
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.
