Phase Equilibria of Clathrate Hydrates of Tetrahydrofuran + Hydrogen Sulfide and Tetrahydrofuran + Methane
Résumé
In this work, experimental dissociation data for the clathrate hydrates of tetrahydrofuran + hydrogen sulfide and tetrahydrofuran + methane are reported. The experimental data were generated using an isochoric pressure- search method. The dissociation data for the tetrahydrofuran + methane clathrate hydrates are compared with the corresponding experimental data reported in the literature, and the acceptable agreement demonstrates the reliability of the experimental method used in our work. Moreover, we extend the literature data for the latter system to a low concentration of tetrahydrofuran in its aqueous solution. As addition of high concentrations of tetrahydrofuran in aqueous solution diminishes its pressure-reducing effect, we therefore measured and report the experimental dissociation data for the tetrahydrofuran + hydrogen sulfide clathrate hydrates at low concentrations of tetrahydrofuran in its aqueous solution.
