METHOD FOR DETERMINING THE EQUILIBRIUM THERMOBARIC PARAMETERS OF HYDRATE FORMATION FROM A MIXTURE OF LIQUEFIED GASES Russian patent published in 2022 - IPC G01N7/00 

FIELD: equilibrium thermobaric parameters determination.

SUBSTANCE: invention relates to methods for determining the equilibrium thermobaric parameters of the formation of hydrates from a mixture of liquefied gases and can be used in the oil, gas and chemical industries. The method for determining the equilibrium thermobaric parameters of the formation of hydrates from a mixture of liquefied gases includes determining the component composition and temperature of the hydrate-forming mixture, the pressure of formation of hydrates in it of each component and the mixture according to calculation formulas using coefficients in them, while the pressure of formation of hydrates in it of each component of the mixture is determined by the formula: , where T is the temperature of the mixture (K); P_i - equilibrium pressure of each i-th component (MPa); a, b, c - coefficients; and the equilibrium pressure of the mixture - according to the formula: , where X_i is the mole fraction of the i-th liquid component in the hydrate.

EFFECT: increasing the efficiency of determining the equilibrium thermobaric parameters of the formation of hydrates from a mixture of liquefied gases.
