基于断链理论的油氢合建站安全设计及标准研究

ON SAFETY DESIGN AND STANDARDS OF OIL-HYDROGEN REFUELING STATION BASED ON CHAIN-CUTTING THEORY

油氢合建站是目前发展加氢基础设施的理想过渡方案,但是其设计、建设等标准仍十分缺乏。为推进油氢合建站的建设,中国石化发布了企业标准《加氢站、油氢合建站安全技术规范》(Q/SH 0829—2021)。基于该标准的编制过程,构建油氢合建站的事故链模型,结合断链理论和数值模拟的方法,分析并解释了标准中若干条款提出的背景和原因。该标准是中国石化发展油氢合建站的重要依据,为油氢合建站的工程设计及生产运营提供指导,其发布与实施有显著的推广和示范意义。

The oil-hydrogen refueling station is an ideal transition plan for the development of hydrogen refueling infrastructure,but the design and construction standards for it are still very scarce.To promote the construction of oil-hydrogen refueling stations,SINOPEC has released enterprise standard Safety Technical Specifications for Hydrogen and Oil-Hydrogen Refueling Stations(Q/SH 0829-2021).Based on the preparation process of this standard,an accident chain model for oil-hydrogen refueling stations was constructed.Combining with the chain-cutting theory and numerical simulation,this paper analyzed and illustrated the background and reasons for several provisions in the above standard.This standard serves as the important basis for SINOPEC to develop oil-hydrogen refueling stations,and it provides guidance for engineering design and production operation of oil-hydrogen refueling stations.The publication and implementation of this standard is of great value in promotion and demonstration.
