Equilibrium Hydrate Formation Conditions for Hydrogen Sulfide, Carbon Dioxide, and Ethane in Aqueous Solutions of Ethylene Glycol and Sodium Chloride

Abstract

Incipient equilibrium hydrate formation conditions for hydrogen sulfide, carbon dioxide, and ethane in aqueous solutions of ethylene glycol and sodium chloride were experimentally obtained in the temperature range 264−290 K and the pressure range 0.23−3.18 MPa. A variable-volume sapphire cell was used for the measurements.
