摘要：Chemical processes frequently involve separation of multicomponent mixtures into multiple products by a sequence of separators, each of which produces generally two but sometimes more than two product or intermediate streams. The products may consist of relatively pure species, or they may be multicomponent products that contain two or more major species. Early research on the synthesis of separation sequences (primarily sequences involving only ordinary distillation) was directed towards the identification of useful heuristics.For the three component mixture to be split into three relatively pure products, there are only two alternative sequences. The complexity increases significantly as the number of products increases. There may be many ways in which the separation can be carried out to produce the same products. The problem is that there may be significant differences in the capital and operating costs between different distillation sequences that can produce the same products.In the present work, the system of multicomponent mixture is selected for optimal sequence and the optimization is carried out by conventional method. In the conventional method, different trial and error calculations have been employed to arrive at optimal sequence. The results obtained by conventional means are summarized and then compared to find out the optimal sequence of the selected system.
