Abstract: In distillation process synthesis as the number of components increased the number of sequences exponentially increased. Besides, there are different categories of sequences which could be considered in the synthesis. So, search space reduction methods are crucial to reduce the number of the candidates and reduce the analysis time. In the present work, a new search space reduction method based on exergy analysis is presented and applied for 3 different samples of three component mixtures (ESI > 1, ESI ≈ 1 & ESI < 1). The feed mixture has been tested under three different compositions. The results of the case study were illustrated that the new method could reduce the amount of calculation between 11 and 50%.
