大气压变化对LNG接收站BOG的影响

摘要

以国际标准和权威文献为依据,通过理论分析和实例计算,从不同角度深入解析了大气压变化对LNG接收站BOG的影响.其中,由大气压下降引起储罐气液界面处闪蒸产生的BOG量约是气相膨胀产生BOG量的0.80倍,在计算中不应被忽略.%s:Based on international standard and authoritative literature, the influence of barometric pressure fluctuation on the generation of BOG from LNG terminal is multi-dimensionally investigated through both theoretical analysis and calculation. During the calculation of BOG from barometric pressure fluctuation, attention should be paid to the generating amount from gas-liquid interface of storage tank, which is about 0.80 times of that from expansion of gas phase.
