Equilibrium Conditions of Xenon Hydrates in the Presence of Aqueous Solutions of Alcohols, Glycols, and Glycerol

Equilibrium conditions of xenon hydrates in the presence of aqueous solutions of alcohols, glycols, and glycerol were experimentally measured in a pressure range up to 1 MPa using an isochoric method. Adding the chemicals to water lowered the equilibrium temperature of xenon hydrate, indicating that the chemicals acts as the hydrate inhibitors. On a mass basis, the inhibiting effect on xenon hydrate formation decreased in the following order: methanol > ethanol > ethylene glycol > glycerol approximate to diethylene glycol > triethylene glycol. The order is the same as those for other hydrates of ethane, propane, and carbon dioxide.
