| 摘 要： | <正>在伴有多个反应的分离过程数学模拟中,反应量的存在使模型变量增多,非线性增强.文献1～3]在普通精馏的基础上,提出了不同的算法来改进收敛性.他们对各种反应类型,均以动力学计算反应量,迭代变量多,算法也较复杂.Doherty针对平衡反应过程,提出了变换组成变量的概念计算反应相平衡.本文引入此概念,并对流率、焓等物理量进行了相应的变换,使变换后的反应精馏过程数学模型在形式上与普通精馏过程的模型完全一致.并以修正的Newton-Raphson法对对二甲苯和邻二甲苯的反应精馏过程进行了计算.

| Abstract: | A method is presented to transform the equations describing steady reactive distillation with chemical reactions and inert components into a new set of equations. The formulating style of the new model is similar to traditional distillation model. Moreover, an algorithm which is based on the modified Newton-Raphson method is developed to solve the simultaneous equations. The reactive distillation process for separating o-and p-xylene is simulated as numerical example. |
