Experimental Investigation of Carbon Dioxide Hydrate Formation Conditions in the Presence of KNO₃, MgSO₄, and CuSO₄

Experimental data on the incipient conditions for carbon dioxide hydrate formation in aqueous solutions of KNO 3, MgSO 4, and CuSO 4 were obtained in the temperature range of (273 to 287) K, in the pressure range of (0.77 to 4.34) MPa, and in salt concentrations ranging from (2.22 to 40.17) mass %. A variable-volume sapphire cell was used for the measurements.
