摘要
讨论了考虑任意塔板可以存在交联流股的通用精馏过程的数学模型.以分离苯、甲苯、邻二甲苯物系的热偶精馏过程为计算实例,采用同伦延拓算法求解,在多种工况下均得到多解,并从中找出操作特性、经济效益均佳的设计条件.
A generalized mathematical model used in complex distillation processes, which takes into account interlinks, is presented in this paper. The Petlyuk systems for separating benzene, toluene and o -xylene are simulated by using the homotopy continuation method. Multiple steady state solutions under many different specifications are discovered. The optimal design conditions for the compler distillation process have been found from the simulation results.
