Abstract: Energy is the key force to promote social and economic development. As a new energy source,low-temperature liquefied hydrocarbon has shown important value. Based on Jiangsu Zhongfuel Yanchang liquid hydrocarbon storage project,the storage method of low-temperature liquefied hydrocarbon and the cause for the generation of boil-off gas （BOG） under low-temperature atmospheric pressure storage are analyzed,and the calculation method and treatment process are described,which have a far-reaching impact on the storage method,treatment process and actual operating cost of BOG in the plant.

Key words: energy, low-temperature liquefied hydrocarbon, BOG treatment
