A new experimental setup has been validated to measure gas solubility at low-temperature and high-pressure conditions. Solubility of natural gas components, for example, methane, nitrogen, and carbon dioxide, was measured in aqueous solutions of (40 and 60) mass % of ethylene glycol at (15.00 and 20.00) MPa and at temperatures of (-10.0, 0.0, and 10.0) degrees C.
