An apparatus and experimental technique are described for measuring gas solubilities in liquids at elevated temperatures and pressures. The apparatus has been designed to operate at pressures up to 100 bar and temperatures up to 70 °C. The technique has been used to measure H2 solubilities in perfluoropropane (C3F8) and perfluoropropylene (C3F8) at pressures up to 20 bar and temperatures from 0 to 50 °C. Two methods of regressing the experimental data to give Henry's law constants and for extrapolating gas solubilities beyond the experimental temperature range are also compared.
