Phase Equilibria of Clathrate Hydrates of Cyclopentane + Hydrogen Sulfide and Cyclopentane + Methane

Abstract : In this work, experimental hydrate dissociation data for the hydrogen sulfide + cyclopentane + water and methane + cyclopentane + water systems are reported in the temperature ranges of 295.4-310.0 K and 284.8-299.3 K, respectively. The experimental data were generated using an isochoric pressure-search method. The hydrate dissociation data for the methane + cyclopentane + water system are compared with some selected experimental data from the literature, and the acceptable agreement demonstrates the reliability of the experimental method used in our work. The experimental data for both measured systems are finally compared with the corresponding literature data in the absence of cyclopentane to study its hydrate promotion effects.
