An original method for calculating the equilibrium pressure for the formation or dissociation of multicomponent gas hydrates as a function of temperature and composition has been developed. It is applicable to gas and water systems that are in the following phase states: gas–water vapor–ice; gas–water vapor–liquid water. The developed method is suitable for determining the equilibrium conditions for the formation (dissociation) of hydrates of multicomponent gases depending on their composition with an accuracy of about 1%. The novelty of the developed method is protected by a patent of the Russian Federation.
