【摘要】：为了能输送和存储单相低温液体,保证输送管道和低温储罐的安全,预冷过程不可或缺。对预冷时间、预冷介质消耗量进行预测有利于指导实际操作。从热力学基本理论出发,采用稳态与变热导率的热力学分析方法,建立储罐预冷时间与预冷介质消耗量数学模型,推导了储罐温度随时间的变化关系,探讨进口流量与预冷时间、预冷介质消耗量之间的相互影响。将不同的计算方法相结合,指导选取最佳预冷流量。
[Abstract]:In order to transport and store single phase cryogenic liquid and ensure the safety of pipeline and cryogenic storage tank, the precooling process is indispensable. The prediction of precooling time and consumption of precooled medium is helpful to guide practical operation. Based on the basic theory of thermodynamics, the mathematical model of precooling time and consumption of precooled medium is established by using the thermodynamic analysis method of steady state and variable thermal conductivity, and the relationship between tank temperature and time is deduced. The interaction between inlet flow rate, precooling time and consumption of precooling medium is discussed. Different calculation methods are combined to guide the selection of optimal precooling flow rate.
