摘要
以年费用为目标函数，对22个分离5组分混合物的精馏流程进行了研究．除了简单塔的14个序列之外，还包含8个含复杂塔（侧线汽提和／或侧线精馏塔）的流程.以不同的物系在不同的进料组成下，对流程的分离费用进行实例研究，通过分析得出构造含复杂塔精馏流程的实用规则.
Twenty two distillation flowsheets are studied for the separation of five-component mixtures based on energy consumption and annual costs.Fourteen flowsheets with simple columns and eight flowsheets with complex columns of side strippers and/or side rectifiers are included. Several five-component mixtures are selected,and for various cases of feed composition distribution,the costs of the flowsheets are calculated and compared.Several heuristics are produced for the synthesis of distillation flowsheets with complex columns.
