| 摘 要： | 以文献中的相平衡数据为基础，利用Aspen Plus 软件，建立N-甲酰基吗啉（NFM）芳烃萃取精馏工艺模型。模拟结果表明：该模型可以较好地反映装置的实际操作状况。考察剂油比、贫溶剂进料温度以及贫溶剂中苯含量等参数对分离过程的影响，获得N-甲酰基吗啉芳烃萃取精馏工艺的最佳操作参数为：剂油质量比4.66，贫溶剂进料温度112 ℃，贫溶剂中苯质量分数在1%左右。优化工况的模拟计算结果表明，优化后苯收率和苯纯度明显提高，其中苯收率提高0.6百分点，苯纯度提高0.06百分点。

| Abstract: | Using Aspen Plus software,a process model of separating aromatics from non-aromatics by extractive distillation with N-formylmorpholine(NFM) is set up based on vapor-liquid equilibrium data of NFM andhydrocarbons system.Simulation results show that the calculations agree well with the actual operation data.The effect of solvent/oil ratio,inlet temperature of lean solvent and benzene content in lean solvent on the separation is investigated.Optimum operation parameters are obtained as follows: solvent/oil mass ratio of 4.66,lean solvent inlet temperature of 112 ℃ and mass fraction of benzene in lean solvent of about 1%.Calculations under optimization conditions show that the yield and purity of benzene enhance significantly,they increase 0.6 and 0.06 percentage points,respectively. |
