| 摘 要： | 针对褐煤气化、合成等工序得到的甲醇合成油芳烃含量高的特殊情况,提出采用分馏-脱轻-脱重工艺路线来富集高浓度均四甲苯的分离方案。通过流程模拟计算发现,分馏塔在常压条件下,当塔顶温度为129.7℃、塔底温度为211.5℃时,分馏得到的均四甲苯富集液质量分数为71.72%;在真空操作下,通过脱轻塔和脱重塔脱除轻组分和重组分后,可得到质量分数高达91.3%的均四甲苯溶液。精馏实验证明,上述工艺路线是可行的。 |

| Abstract: | As the methanol synthetic oil,produced from lignite gasification and other synthetic processes,has high content of aromatic,a method of the extraction of high concentration durene from methanol synthetic oil by fractionation as well as the removal of light component and heavy component has been proposed.The simulation results showed that,at atmospheric conditions,durene concentration reached 71.72% when top temperature was 129.7 ℃ and bottom temperature was 211.5 ℃ in fractionator,then under vacuum condition durene solution could be concentrated up to 91.3% by removing light fraction and removing low boiling and high boiling fractions in two rectifying columns.The feasibility of the process route was verified in a distillation column with the diameter of 30 mm. |
