三元混合制冷剂R290+R600a+N2汽液相平衡实验研究
Measurement of vapor liquid equilibrium for ternary refrigerant mixture R290+R600a+N2
摘要
Abstract
In hydrogen liquefaction process,precooling cycle is an important link,among which the unit energy consumption of MR is relatively low,so it is particularly important to optimize the performance of MR.In this pa-per,the experimental system of VLE was built by the method of single-phase liquid phase cycle,and the prop-erties of VLE in the ternary system R290+R600a+N2 were studied.The temperature range of 273.15 K～323.15 K was used to study the ternary mixing medium R290+R600a+N2,and 18 groups of experimental data were obtained.At the same time,Peng-Pobinson-Stryjek-Vera(PRSV)equation of state combined with van der Waals(vdW)mixing rule was used to calculate the VLE properties of the ternary system.By comparing the experimental data with the calculated results,the average absolute relative deviation AARDp of the system pres-sure is 0.85％,and the average absolute deviation AADy1,AADy2 and AADy3 of the system components R290,R600a and N2 are 0.0064,0.0027 and 0.0063,respectively.关键词
