Dielkometric testing method of composition and phase state of cryo-agents, used in water transport This article represents the results of experimental studies of electrophysical properties, in particular, the dielectric constant of “liquefied natural gas (LNG)” as a mixture of liquefied gases, that is correct from a practical point of view, as well as for the development of fundamental knowledge on estimate of the dielectric virial coefficients and the values of the molar polarization of methane and nitrogen with the line parameters saturation. The developed designs of high-capacity measuring cells can be used to estimate the phase state and composition of LNG in gas carrier tanks and cryogenic vessels of cryogenic fuel systems of ship gas diesel engines.
