摘　　要：目前国内外大多数接收海运来料的LNG接收终端采用蒸发气(BOG)再冷凝工艺。在对再冷凝工艺流程进行热力模拟的基础上,提出了各流程性能的计算公式,分析了LNG组分、储存温度、BOG排出压力、BOG压缩机和罐内泵出口压力、外输天然气压力和温度等流程参数对压缩机和泵的功耗、各换热设备的换热量、海水流量等流程性能的影响,根据每一参数的影响趋势提出了流程操作建议,从影响范围和影响度两个方面总结了流程参数对流程性能的影响程度。Nowadays,BOG recondensation process was adopted by most terminals to receive shipping LNG.Based on the thermodynamic simulation of recondensation process,the paper provided calculation formulas of process performance,analyszed the influence of the process parameters on the power of compressor and pumps,energy of several heat-exchangers and flow of seawater,including LNG compositions,storaging temperature,discharged pressure of BOG,outlet pressure of BOG compressor and in-tank pump,the pressure and temperature of product gas.At the same time,operation suggestions were provided according to the influencing trend of each parameter.The effect of parameter on the performance also was summarized from influence scope to influence grade.
