通过对精馏实验设备进行改造,在每套设备上安装了回流温度测定装置,并要求学生在冷液回流的操作条件下进行精馏试验,自己设定回流温度、进料热状态、回流比等实验参数,通过对精馏过程的物料衡算和热量衡算,确定精馏塔的内回流量及精馏段操作线方程,并进行精馏分离效果的分析。
Refurbishment of the experimental equipment through the transformation in each set of equipment installed on the back-flow temperature measurement device, and requires students to operate under the conditions of the backflow of liquid reflux distillation test, set their own reflux temperature, feed the heat state, the reflux ratio And other experimental parameters, through the distillation process of material balance and calorific value calculation to determine the rectification tower reflux and rectification section operating line equation, and distillation separation effect analysis.
