Calculation of three-component gas distillation
Thread Content
May I ask how to calculate the theoretical number of theoretical plates for the distillation of a three-component gas? The flow rates of the feed, the top discharge, and the bottom discharge, as well as the concentrations of various components, the thermal state of the feed, the reflux ratio, and so on are known
The general steps are as follows: 1. Analyze and separate the tasks. 2. Determine the process flow, as well as the light and heavy key components in each column. 3. Use simplified algorithms to estimate the minimum reflux ratio and the minimum number of theoretical plates. 4. Analyze the relationship between the reflux ratio and the number of theoretical plates, conduct an investment estimate, and select an appropriate number of plates. 5. Perform detailed calculations for each individual plate. 6. During industrial design, the plate efficiency should be determined based on the properties of the material, such as viscosity and surface tension. Methods include: 1. Manual calculation; 2. Software-based calculation using tools like Aspen and ProII. . . . . Refer to https://bbs.hcbbs.com/thread-2773408-1-1.html
