The experimental procedure for determining the initial hydrate formation conditions along the univariant gas‐water rich liquid‐hydrate locus through the measurement of equilibrium pressures and temperatures alone in a constant volume system has been successfully applied to several binary gas mixtures with water to pressures as high as 15,000 lb./sq. in. The general hydrate theory of van der Waals and Platteeuw, after appropriate modifications, was found valid for the accurate prediction of the initial hydrate formation conditions for selected mixtures of argon‐methane and argon‐nitrogen. The calculated methane‐argon compositions in the hydrate phase are presented as a function of the methane‐argon composition in the gas phase on a water‐free basis but were not verified experimentally.
