Methane hydrate formation experiments in the presence of the various imidazolilium based ionic liquid solutions with 0.5wt% concentration including 1-buthyl-3-methylimidazolium methyl sulfate ([BMIM][MeSO4]) , 1-ethyl-3-methylimidazolium hydrogen sulfate ([EMIM][HSO4]), 1- ethyl-3-methylimidazolium ethyl sulfate ([EMIM][EtSO4]), 1-butyl-3-methylimidazolium tetrafluoroborate ([BMIM][BF4]) and 1-(2- hydroxyethyl)-3-methylimidazolium tetrafluoroborate ([OH-EMIM][BF4]) were conducted in a high pressure reactor at the same temperature. The induction time, gas consumption and temperature were measured.The results of experiments were indicated that [EMIM][EtSO4] and [BMIM][MeSO4] had the kinetic inhibiton effects meanwhile the other ionic liquids could be able to apply as the kinetic promoters
Phase equilibrium measurements for hydrates of the CH4 /CO2 / 1, 4-Dioxane aqueous solution system
The equilibrium compادامه/دانلودرایگان!
The equilibrium compositions and properties of CO2/CH4/1,4-dioxane/water hydrate were studied for the first time at temperatures ranging from 273.65 to 281.35K and pressures ranging from 0.5 to 1.1MPa. The gas mixture consist of about 45% CO2 was used to be an exemplary for biogas and landfill gas operations. Equilibrium hydrate formation conditions for above system were measured. 1,4-Dioxane lowered equilibrium pressure by 2MPa comparing with pure water at some temperatures. This is an indication that structural transition from SI to SII was occurred
