摘要
反应精馏平衡级模型方程反应项引入可变参数λ ;模型求解将变量分内、中、外三层迭代 ,计算结果表明算法易收敛、准确性较高、初值易给定。以乙醇乙酸酯化反应精馏过程为例 ,就过程参数对反应精馏的影响进行了计算。
Adjustable parameter λ has been introduced in the reaction rate item during the simulation of a reactive distillation process. The simulation procedure is programmed to three loops: the inner, the middle and the outer one. It is demonstrated that the presented algorithm is of accuracy in results and converges steadily even if an arbitrary initial value is given. As an example the reactive distillation process of ethanol\|acetic acid was used to test the algorithm, and to obtain message of the effects of process parameters on the system.
