Equilibrium data for hydrogen sulfide clathrate hydrates in the presence of methanol, ethanol, NaCl, KCl, or CaCl2 aqueous solutions are reported in this work. The experimental data were generated using an isochoric pressure-search method. These data are compared with the literature data in the presence of pure water to identify the hydrate inhibition effects of the aforementioned aqueous solutions.
