Preservation of Methane Hydrates Prepared from Dilute Electrolyte Solutions
Figure 3
Residual fraction of methane in hydrate samples after an isothermal hold for 150 hours. (a) Samples prepared from pure water, 1.0 mol/m3 aqueous sodium chloride, 0.50 mol/m3 aqueous magnesium chloride, or 0.50 mol/m3 aqueous sodium sulfate. (b) Samples prepared from sodium chloride solutions of various concentrations.
