Rice University conducted experimental measurements of water content in a gaseous phase of a fixed composition (5.31 mol% propane in methane) in equilibrium with hydrate for pressures of 300, 500, 1000, and 1500 psia and temperatures ranging from 234 to 278 K. The water content in the gas mixture shows much lower values than those obtained at the same condition for methane gas. Moreover, the discrepancies continue to increase as the temperature decreases. Predictions of water content in the gaseous phase, made using the solid solution theory of van der Waals and Platteeuw and the Redlich-Kwong-Soave equation of state, assume that only structure II crystals were formed at all of the experimental conditions of this investigation. The predictions closely agree with both the smoothed experimental data and the raw data, in view of the uncertainties involved in measuring small concentrations of water.
