Abstract

Gas hydrates or clathrates are non-stoichiometric complex compounds. At appropriate conditions, due to hydrogen bonding, the water molecules form cage-like structures and if gas molecules enter those cavities, the structures stabilize. Generally the determination of thermodynamic equilibrium formation and dissociation conditions is very time consuming process. In this article, an innovative direct and fast method was developed for determination of thermodynamic equilibrium conditions. All of the experiments were performed in a high pressure PARR reactor using distilled water and methane with 97.37 percent purity. In this method, memory effect of the distilled water at each experiment has been removed at 40oC. The equilibrium hydrate formation pressure was determined at desired temperatures. The obtained equilibrium pressures were 598, 651, 727, 909, and 1053 psia at 4, 5, 6, 8, and 10oC, respectively. Repeatability of this method was also investigated. The obtained data are in good agreement with those of reported by Deaton and Frost, predicted by HWU correlation and CSMHYD hydrate software, and to those predicted by Kamath correlation. The average absolute deviations of equilibrium pressure in all experiments were only 7.86 and 5.24 percent when compared to predictions of HWU correlation and CSMHYD software, respectively.
