摘　　要：“混合轻烃”是油气田伴生气和进口液化天然气中烷烃的提取物,近年市场供应逐渐增加。由于其和传统的以液化石油气为代表的烃类混合物的组分上的差别,国内缺乏对应的生产规范与储运设备,为生产与贸易带来不便。为此针对混合轻烃在装卸与运输环节中的危险性,利用可解释结构模型(ISM)对衍生的安全管理措施之间的逻辑关系进行拓扑结构呈现。结果表明:若沿用市场现有的LPG槽车运输混合轻烃则必须充分计算其工艺可靠性,提前评估这类产品的事故风险以及选择合理的包装方式,并做好设备日常维护等保障性工作;其他因素的重要度依此变化,可为安全防范提供参考;在日常的安全管理工作中,安全专项资金的投入是最基本的保障,其次是生产规章制度与安全管理规程的科学性,以及如何平衡生产效率与安全之间的关系。“Mixed light hydrocarbons”is an extract of alkanes from associated gas in oil and gas fields and imported LNG,and the market supply is gradually increasing in recent years.Due to the difference in components of these hydrocarbon mixtures from traditional LPG,there is a lack of cor-responding production standards and storage and transportation facilities in China,which brings in-convenience to production and trade.In view of the hazards of mixed light hydrocarbons in the han-dling and transportation processes,the topology of logical relationships between derived safety man-agement measures is presented by using the Interpretable Structural Model(ISM).Here are the re-sults:first,if the existing LPG tankers are used to transport mixed light hydrocarbons,the process reliability must be fully calculated,the accident risk of these products must be evaluated in advance and reasonable packaging methods must be selected,and the daily maintenance of equipment must be done;second,the importance of other factors varies accordingly;third,investment of special safety funds is the first basic guarantee in daily work of safety management,the second is the scien-tific nature of the production regulations and safety management procedures,and how to balance the relationship between production efficiency and safety.
