Synthesis and phase transformations of natural gas hydrates of Srednevilyuiskoe field

摘要

The study discusses the results of investigations of a natural gas hydtrate formation of Srednevilyuiskoe field in various model systems based on distilled water by DSC. Based on the calculated data conditions for synthesis of natural gas hydrates in a calorimeter cell were selected and thermobaric conditions of formation and decomposition of hydrates under study were found. It was shown that in the presence of surfactants the process of the natural gas hydrate formation led predominantly to the formation of methane hydrates. An influence of mechanical admixtures and surfactants on supercooling was determined, which in turn affects the crystallization temperatures of systems under study.
