LNG加气站BOG用于站内生活用气的可行性探讨

Discussion on the feasibility of using BOG for life in a LNG filling station

摘要: 目前国内大多数LNG加气站产生的BOG都直接排放，造成能源浪费和安全风险。在LNG加气站工艺流程分析的基础上，探讨了LNG加气站内BOG的来源，对BOG回收作为站内自用气(采暖、做饭、淋浴)的可行性进行了研究，并通过实例计算，从经济角度论证了BOG回收作为站内自用气的可行性。结果表明，将LNG加气站BOG回收作为站内自用气的方案具有可行性，不仅能够带来可观的经济效益，而且对LNG站场运行安全具有重要意义。

Abstract: Nowadays in China, BOG generated in LNG filling station is released directly, which leads to the waste of energy and the risk of safety. Based on the analysis of LNG filling station process flow, the source of BOG in LNG filling station is discussed, and the research on feasibility of using BOG for life (heating, cooking, showering) is carried out, as well as a real station for an example, the practicability from economic angle is discussed. The results show that it is feasible to use BOG for life and has not only economic benefits but also an important meaning for the safety of a LNG filling station.
