efining, petrochemical and other industries. Distillation process in energy agent driven, gas-liquid two-phase repeatedly direct contact with and separation, using liquid mixture ponents of the volatility of the different, the ponents from liquid to gas phase transfer, difficult volatile points from gas phase to liquid phase transfer, realize the separation of ponents of the raw material mixture. The subject of this design is the design of the plate column of the two element system of benzene and toluene. In determining the process requirements, to determine the design scheme, design content including calculation of distillation process design, tower auxiliary equipment design and calculation, distillation process flow chart, equipment structure diagram of distillation column design manual
