板式连续精馏塔醇水体系的实操效果与 Aspen Plus软件模拟结果对比分析.

The paper compares the practical effect of the distillation column in laboratory for alcohol water system with the simulation results by using Aspen Plus software. We have calculated theoretically the potential applications of plate distillation column. We also have realized the actual verification of simulation software with chemical experimental data. First of all, we carried out a continuous distillation of alcohol solution with a certain concentration in the laboratory. The diameter of the distillation column is 68 mm and the plate number is 10. Then, we use the Aspen Plus software to simulate the same system. The measured data and the simulation results are compared in details. The results show that the composition of inlet and outlet measured by experiment is different in some degree from that calculated by Aspen Plus software. But the deviation is within a reasonable range. The data of operating line of the rectifying section and stripping section, the actual reflux ratio and feed position which obtained from experiment are in good agreement with the Aspen Plus software calculation results. In this paper, we have further verified that the design and calculation using Aspen Plus software meet with the experimental data. The results are available. [ABSTRACT FROM AUTHOR]
