摘要：
A stochastic programming modeling framework based on mass transfer mechanism was proposed, which took the uncertainty of crude oil properties into consideration, to achieve the simultaneous optimization of economic performance and disturbance rejection ability of refinery hydrogen network. The framework integrated process units such as atmospheric and vacuum distillation, hydrofining and flash separation to analyze the impact of crude oil properties fluctuations on network operation microscopically; adopted surrogate-assisted techniques to embed desulfurization unit and used the two-stage stochastic programming approach to retrofit network, so as to optimize hydrogen network macroscopically to meet production requirements. To verify the effectiveness and applicability of the proposed method, studies on the optimization design of an industrial hydrogen system were presented. The results show that the multi-scenario optimization strategy integrated process units can effectively improve the economic performance of hydrogen network. And it can flexibly respond to changes in operating scenarios caused by fluctuations in crude oil properties. © 2022, Editorial Board of CIESC Journal. All right reserved.
