【摘要】 本文对废液中低浓度乙醇的回收再利用进行了研究,主要对低浓度乙醇精馏过程中的不同实验条件进行了初探,得出了塔釜加热电压,塔釜液浓度,回流比等实验条件与塔顶产品浓度之间的关系,并用计算机绘制了图表,确定一组最优的实验条件。更多还原

【Abstract】 This article researched recycling the low density ethanol in waste liquid.The main action was exploring different experimental conditions during the process of rectifying the low density ethanol.Through the experiments,the conditions of the experiments such as bottom calefaction voltage,the density of bottom’s liquid and reflux ratio with the density of tip production’s relationship were obtained.Charts were drew by computer and a group of the excellent experimental conditions were determined.更多还原
