| 摘 要： | 以工业醪塔（丙酮－丁醇）为对象，阐述了如何利用ＵＮＩＦＡＣ功能团法建立精馏过程的静态数学模型，针对醪塔模型变量多，非线性严重，不易收敛等情况，提出了一种改进的Ｎｅｗｔｏｎ－Ｒａｐｈｓｏｎ法，保证了算法和收敛性和快速性，根据现场操作数据，对模型进行参数辨识和修正，结果表明模型与塔吻合良好，基于该模型建立了可用于工厂实际操作指导的仿真系统，并以节能粮为目标函数，离线优化了操作条件，为工厂提高经济效益提

| Abstract: | The steady-state modeling of an industrial prefractionator and a simulation system named DISSIMU-I, with vapor-liquid equilibria calculation using UNIFAC group contribution model, is presented in this paper. A new technique is developed to modify the convergence of Newton-Raphson method for the nonlinear multivariable model. The optimal operating conditions are obtained using DISSIMU-I with objective function of energy saving. The scheme of on-line optimal control is also discussed in this paper. |
