Abstract: The structure of side reactors distillation column (SRC) can improve the production process selectivity and conversion rate effectively. The concept of independent reactor calculating is introduced to set up the multi-lateral line feeding equilibrium model of SRC, and Newton-Raphson method used for solving the MESH equations of the model. The method is applied in the distillation simulation for production of chlorobenzene. The model has good convergence effect. In given simulation conditions, when the feeding molar flow rate of chlorine is 8 kmol/h, the product purity of benzene chloride 96.8% and the best feeding molar flow rate of benzene 7.77 kmol/h. The simulation results can be used to guide the production process of benzene chlorination.

Key words: distillation column with side reactors, modeling, simulation, benzene chlorination

摘要： 引入独立反应量概念建立了多侧线进料的带侧反应器的反应精馏塔平衡级模型，并运用Newton-Raphson法解该模型的MESH方程. 将该方法应用于苯氯化反应精馏过程模拟，模型具有很好的收敛效果. 在给定的模拟条件下，Cl2进料量为8 kmol/h时，产品氯化苯纯度达96.8%，最佳苯进料量为7.77 kmol/h. 模拟结果可用于指导苯氯化生产.
