提出了一种基于代码矩阵的精馏序列合成方法及其算法实现。该方法包括混合物组群划分、减塔配置基本搜索空间的创建、代码矩阵的生成和使用分离限制条件筛选4个步骤。由于代码矩阵衍生自矩阵法的0-1矩阵，且其元素代码包含了精馏塔分离编号和产品流股的采出位置等信息，因此，该合成法不仅能提供完整的精馏配置搜索空间，而且便于根据分离限制要求进行分离序列的筛选。文中给出该方法在乙二醇粗产品体系的应用，由VB计算共获得了8个三塔分离方案。结合Aspen模拟，得到总再沸器热负荷最小的三塔分离方案。

A code matrix-based synthesis method for multicomponent distillation sequences is described as well as its algorism. Four steps, such as grouping the components of feed, generating the basic search space of sub-column configurations, transforming 0-1 matrices into code matrices and eliminating configurations with separation constraints, are included in this method. The code matrices, whose element code includes the information about the column sequence number and the location of product withdrawing, are transformed from 0-1 matrices determined by matrix method. Thus, this method not only provides a complete set of separation configurations with sharp or non-sharp split but also can pick out all the desirable configurations with the constraints by logical programming. Additionally, the use of this method is illustrated by applying it to the ethylene glycol purification from dimethyl oxalate hydrogenation. Eight configurations are selected out and one configuration with the lowest total reboiler heat duty is identified by Aspen Plus optimization.
