Experimental and modeling investigation on mixed carbon dioxide-tetrahydrofuran hydrate formation kinetics in isothermal and isochoric systems

In this study, the kinetics of (carbon dioxide + THF) hydrate formation is investigated experimentally in an isothermal and isochoric system. Also, the chemical affinity model is used for modeling the kinetics of hydrate formation. The experiments of hydrate formation have been conducted at temperatures in the range of 275.15-285.15 K and initial pressures in the range of 20.9-26.6 bar. All of the hydrate formation experiments were conducted at a stirring velocity of 800 rpm. The parameters of the kinetic model are obtained for one stage and two stage kinetics. The modeling results show that the chemical affinity model is successfully applied for the kinetics of carbon dioxide + THF hydrate formation. Furthermore, the interpretation of one stage and two stage kinetics is carried out.
