摘要:
采用连续减压侧线精馏对200号聚醚胺进行精制研究,通过Aspen plus模拟软件考察精制过程中各因素对分离效果的影响,优化分离过程条件,确定最佳操作参数. 优化后,侧线采出中目标组分伯胺质量分数为 94.38%,收率为92.01%. 在稳态模拟优化条件基础上,通过Aspen dynamics建立连续减压侧线精馏的动态控制结构,考察了在发生不同扰动工况下各项控制指标的变化情况,结果表明动态控制结构CS1可很好地应对精馏过程的扰动. 在模拟优化条件的基础上,建立连续侧线减压精馏装置进行精馏实验验证,实验值与模拟值基本一致.
Abstract:
No.200 polyetheramines is refined by continuous and vacuum side-line distillation. The simulation study of each parameter in the refining process is carried out by Aspen plus simulation software. The influence of each factor on the side-line distillation effect is investigated. Separation process conditions are optimized to determine optimal operating parameters. At this time,the mass fraction of target component primary amine can reach 94.38%,and the yield is 92.01%. On the basis of steady state simulation optimization conditions,the dynamic control structure of continuous and vacuum side-line distillation is established by Aspen dynamics. The changes of various control indexes under different disturbance conditions are investigated. The results show that the dynamic control structure CS1 can cope well with the disturbance of the distillation process. According to the simulated optimization conditions,the continuous and vacuum side-line distillation unit is established for the experimental verification. The experimental results are basically the same as the simulation results.
