摘要
本文针对多效平流、顺流、逆流三种精馏过程分别建立了设计计算的通用数学模型，并以年总消耗费用最小为目标函数，对三种精馏过程通过实例进行了优化设计计算，结果表明，文中给出的优化设计计算方法，可方便地求出多效精馏过程设计所需的基础数据及系统所需的最小加热蒸汽量。
A general mathematical model for optimal calculation of multi-effect distillation with dual-feed,forward-feed and back-feed is eveloped in this paper. The minimization of the annual cost is taken as the objective function.The example shows that the mathematical model proposed in this paper is effectiv and the minimum heat utility can be obtained for the multi-effect distillations.
