为了解决大规模动态系统模型无法直接求解的问题，利用动态优化方法研究了非线性规划在精馏塔仿真计算中的可行性。针对流程工业中广泛应用的典型二元精馏塔分离过程，对其模型进行离散化，采用非线性规划的方法对其进行稳态计算，评价精馏塔的生产能力；在稳态计算的基础上，利用非线性解题器进行动态模拟，考察不同回流比对精馏塔分离效果的影响。结果显示，稳态及动态模拟计算数据符合工程实践规律与预期。研究表明：非线性规划作为分离过程这类复杂系统的新方法，可为大规模复杂非线性动态系统的模拟分析提供技术支持。

To solve the problem that the large-scale dynamic system model cannot be simulated directly ,this paper evaluates the feasibility of calculation of distillation column model by applying the dynamic optimization method. Aiming at the dynamic model of binary distillation column, the nonlinear programming approach is chosen to simulate the model in static and dynamic pattern re-spectively. The model of binary distillation column is calculated by nonlinear programming solver. The result accords with the engineering practice and can be used to evaluate production capacity of distillation column. With the static calculation,dynamic simulation is executed under various reflux ratio, and the efficiency of separation is also evaluated. The results show that the nonlinear programming is an efficient method for a large-scale complicated system like separation process and provides the technical support.
