HFC134a/HCFC141b混合气体水合物相平衡特性

郭开华;舒碧芬;张奕;赵永利

  In this study, the phase-equilibrium property of the mixed gas hydrate formed by an-other pair of CFC alternatives HFC152a/HCFC141b was measured under a constant volume condition. The phase diagrams of mixed gas hydrates and their characteristics were fur-ther studied, and the phase-equilibrium property of mixed gas hydrates comparing to that of simple gas hydrates was depicted and discussed. The experimental result reveals that HFC134a/HCFC141b mixed gas hydrate has a non-azeotropic melting property, which is different from that of HFC152a/HCFC141b[4]. The melt and freeze points are quite close because the decomposition temperatures of HFC134a and HCFC141b simple gas hydrates have small difference.……
