摘　　要：本文对乙烯液化气船再液化系统的工作情况进行了热力学计算,根据相关要求和数据,计算得出了储罐(液货仓)在不同温度下的充装率,以及温度变化过程中的蒸发率和蒸发量。并针对乙烯液化气船再液化系统中的各个节点的热力学参数值,计算出乙烯液化气船再液化系统流程的重要性能参数。The reliquefaction system of the liquefied ethylene carrier was thermodynamically calculated in detail in the present study. According to the relevant requirements and data, the filling ratio of the storage tank （liquid warehouse） at different temperatures as well as the rate and the quantity of evaporation during the temperature change process were figured out with a series of calculation. In addition, based on the thermodynamic parameter values of the nodes of the reliquefaction system, the important performance parameters of the system were also calculated.
