Phase Equilibria of Hydrates of Furan, Acetone, 1,4-dioxane, Tetra n-Butyl Ammonium Chloride and Tetra n-Butyl Ammonium Floride
In this communicatioرایگان!
In this communication, we first report experimental hydrate dissociation pressures for the methane/ carbon dioxide + furan/ acetone/ 1,4- dioxane + water and the methane + tetra n-butyl ammonium chloride (TBAC) + water as well as the methane /carbon dioxide + tetra n-butyl ammonium floride (TBAF) + water systems in the temperature ranges of (269.9 to 303.3) K. An isochoric pressure-search method was used to generate the experimental data. The hydrate dissociation data are compared with the corresponding literature data and the predictions of a previously reported thermodynamic model and acceptable agreement is observed
Phase equilibrium measurements for hydrates of the CH4 /CO2 / 1, 4-Dioxane aqueous solution system
The equilibrium compرایگان!
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
