【摘要】：為了能輸送和存儲單相低溫液體,保證輸送管道和低溫儲罐的安全,預冷過程不可或缺。對預冷時間、預冷介質消耗量進行預測有利于指導實際操作。從熱力學基本理論出發(fā),采用穩(wěn)態(tài)與變熱導率的熱力學分析方法,建立儲罐預冷時間與預冷介質消耗量數學模型,推導了儲罐溫度隨時間的變化關系,探討進口流量與預冷時間、預冷介質消耗量之間的相互影響。將不同的計算方法相結合,指導選取最佳預冷流量。
[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.
