| 摘 要： | 提出采用分隔壁精馏塔代替常规精馏塔序列分离松节油以得到α-蒎烯和β-蒎烯的新工艺。为了选择适合松节油体系的分隔壁塔结构,采用Aspen软件分别模拟计算了DWC、DWC-SS和DWC-SR三种塔型,结果表明,与常规工艺相比DWC塔可节能26%,DWC-SS塔可节能16.6%,DWC-SR塔可节能12.5%。在此基础上考察了DWC塔进料位置、回流比、隔板位置、气液相分配比和中间产品出料位置对分离效果和热负荷的影响,得出气液相分配比是影响分隔壁塔操作稳定性的主要因素。

| Abstract: | A novel process was proposed for the separation of α-pinene and β-pinene from turpentine,in which a dividing wall column was adopted instead of the conventional distillation column.To choose the structure suitable for turpentine mixture,three types of divided wall distillation columns were simulated with the software of Aspen plus.Results shows that,compared with the conventional distillation process,DWC could save energy 26.0%,DWC-SS could save energy 16.6%,DWC-SR could save energy 12.5%.And the effect of feed stage,feflux ratio,interconnection stage,side product stage,and distribution ratio of vapor and liquid on the separation efficiency and reboil duty were investigated especially through sensitive analysis,then the main parameter of the column was determined. |
