Cyclopentane hydrate cohesion measurements and phase equilibrium predictions

In order to further understand these systems, an understanding of the thermodynamic phase equilibria for systems containing cyclopentane is needed. The prediction capability of the in-house hydrate phase equilibria prediction tool (CSMGem) was therefore improved by optimizing the Kihara potential parameters for cyclopentane using pure and mixed cyclopentane hydrate phase equilibria experimental data. The optimized set of Kihara parameters was then used to predict the gas hydrate phase boundary as well as the fractional cage occupancy of guest molecules, where the larger cavities of structure II were confirmed, as expected, to be filled only by cyclopentane molecules.
