| Abstract: | In this study,the superiority of growth kinetics and phase-equilibrium properties of binary gas hydrates compared with that of simple gas hydrates is depicted and discussed.It reveals that induction time is shorted and formation rate is accelerated,also the azeotropic melting property and non-azeotropic melting property are shown.By the blend of HCFCS alternatives,due to the super principle of property compensation of mixtures,new environmental working medium pairs for binary gas hydrates are presented and summarized.At last,the problems on working medium Suitability are presented,the application for binary gas hydrate for cool storage is predicted. |
