摘　　要：以优级酒精差压蒸馏工艺中脱甲醇塔为基础,考察不同塔板层数、进料位置、回流比对优级成品酒精品质的影响。通过优化分析,脱甲醇塔设置60层,进料层数定在30层,回流比定在3.00左右时,优级成品酒精中甲醇含量可降到9.91 mg/L。分析结果可为企业生产实践和诊断优化提供数据支持。A demethanol column in alcohol distillation process of guaranteed reagent grade was researched. The effects of different tray numbers, feed position and reflux ratio on guaranteed reagent grade alcohol quality were analyzed. Optimization results showed that when demethanol column was designed with 60 layers, the feed stage was located on the 30th tray, and reflux ratio was about 3.00, the methanol concentration in guaranteed reagent grade alcohol can be reduced to 9. 91 ppm. The analysis results can provide data support for enterprise production diagnosis and optimization.
