METHOD OF DETERMINING THERMOBARIC PARAMETERS OF HYDRATES FORMATION IN MULTICOMPONENT MIXTURE Russian patent published in 2017 - IPC G01N7/00 G01K13/00 G01N25/02 

FIELD: chemistry.

SUBSTANCE: method of determining thermobaric parameters of hydrates formation in multicomponent mixture includes definition of composition and temperature of the mixture, and it hydrates formation pressure on calculation formulas linking these parameters using these coefficients, determined empirically. Moreover, the hydrate forming components entering the mixture are further determined, and then one of the two temperature ranges into which the temperature of the mixture falls is determined, the first range is from 80 to 273.15 K, the second from 273.15 (inclusive) to 320 K. For each such component, the pressure of the onset of formation of its hydrate at the temperature of the mixture in the first range is determined by the power law or by the temperature of the mixture, and in the second range by the exponential dependence. Further, the formation pressure of the hydrates in the multicomponent mixture is determined in the first temperature range or in the second temperature range.

EFFECT: increasing the accuracy and reliability of the determination of hydrate-forming components.
