OPTIMIZATION OF HYDROGEN SYSTEM BASED ON PLAN OPTIMIZATION MODEL

Abstract

Abstract: In this paper, the refinery hydrogen system was reallocated by means of a combination method of hydrogen pinch analysis technology and refinery operation planning optimization model to obtain optimization scheme of hydrogen system. Taking a domestic refinery as an example, the hydrogen reallocated scheme were calculated and analyzed by the pinch theory to meet the hydrogen purity required and to optimize the hydrogen network effectively by the combination method. It is shown by the results that this method can not only save the hydrogen 16.6% but also reduce the crude oil cost, while improves the ability of the refinery for processing lower quality freedstock.

Key words: hydrogen system, pinch technology, plan optimization model, linear programming
