摘要: Abstract Following the report from National Research Council of Canada in 1987 on a new hydrate structure, Sloan and co-workers reported first structure H phase equilibrium data 1992. The present work also reports for methane-2-methylbutane-water, methane-2,2-dimethylbutane-water, methane-tert butyl methhyl ether-water methane-adamantane-water systems. In addition, presence NaCl were obtained three systems are time. indicated that formation pressure, at given temperature, is lower than methane (structure I) pressure salt caused substantial inhibiting effect.
