| 摘 要： | 在筛板塔中对甲醇-乙醇-水三元物系进行精馏传质过程实验，考虑浓度对传质系数的影响建立了一个数学模型，对各组分在塔中的浓度分布进行模拟计算，计算结果能正确反映各组分在塔中浓度分布的变化规律.实验与计算结果都表明在某些浓度范围内乙醇呈现出比较复杂的变化规律.

| Abstract: | Distillation experiments for methanol-ethanol-water system in a tray column were carried out.A mathematics model that takes the effects of concentration on mass transfer coefficients into account is set up for simulation calculation of concentration profiles in the column. The predicted values agree well with the experimental values. Both of experimental and predicted values show that ethanol appears complex concentration profiles in some concentration range. |
