“…The estimation of binary interaction parameters is made basically in the same way as the ordinary (fluid-only) EOS for mixtures; e.g., using VLE (vaporliquid equilibrium), TPx (temperature-pressure-composition) data at some temperatures (or pressures). In the present methane-water system, among several experimental data [27][28][29][30], we have selected VLE data in Ref. 27, which were measured at low temperatures and moderate pressures below the gas hydrate forming conditions.…”

“…The main operational parameters changing during the process are pressure and temperature inside the cell. These two parameters have a direct influence on guest molecule solubility in water which is proved by Song (Song et al, 1997). The results of his experiments state that a gas solubility in water significantly increases at temperatures right above gas hydrate formation temperature and right before hydrate formation.…”

“…Согласно современным данным, для извлечения газа из подводных скоплений гидратов могут использоваться методы, основанные на понижении давления контактирующего с гидратным скоплением свободного газогидратообразователя, на нагреве гидратного скопления, закачке в него ингибитора (например, метанола) и на комбинации этих методов [Sunjay et al, 2011]. Первая опытная добыча такого газа была проведена на севере Канады в дельте р. Макензи (меж-дународный проект «Малик» [Collett, 2005]) и у берегов Японии [Cyranoski, 2013].…”

“…Благодаря низким содержаниям этана и пропана в гидрате равновесная кривая гидратообразования в рассматриваемом эксперименте будет мало отличаться от таковой для гидрата чистого метана. Рассмотрим имеющиеся данные по растворимости метана в пресной воде в равновесии с газовой фазой и гидратом при температурах, близких к 10 °С [Song et al, 1997;Servio, Englezos, 2002;Wang et al, 2003;Davie et al, 2004;Lekvam et al, 2008;Kim et al, 2008;Lu et al, 2008]. Все данные представлены на рис.…”
