An experimental method was generated and proven for the measurement of the water content of a liquid hydrocarbon which is in equilibrium only with hydrates. The method was used to determine the water content of both liquid propane and liquid ethane when hydrates were present, without the presence of a free water phase. The dielectric constant apparatus enabled the water concentration measurement of the hydrocarbon liquid without sample withdrawal. The temperature range was 246-276 K with pressures of 0.77 MPA (propane) and 3.5 MPa (ethane), and the water concentrations in the hydrocarbon were from 16 to 176 ppm (mol).
