A two-step superstructure model was proposed to obtain the minimal usage of hydrogen utility and to facilitate the matches in the hydrogen distribution network in a refinery.
针对炼化企业的氢气分配网络系统，提出了以最小公用工程氢气用量和匹配简化为目标的二步优化模型。
The matching relationships of sources and sinks in hydrogen distribution network are compared before and after optimization. It shows that the superstructure model is effective.
研究表明：采用超结构数学优化模型可以综合考虑系统的各种限制条件对氢气网络进行优化。
Through the case study on a refinery, the new distribution network reduces by 21.21% of hydrogen consumption. The minimum value is realized.
