Analysis of the Techniques for Measuring the Equilibrium Conditions of Gas Hydrates Formation

Data on searching for synergy between alcohol and salt to produce more potent and environmentally benign gas hydrate inhibitors

“…The original research paper describes ramp and step heating techniques for hydrate equilibrium measurements [1] . Their applicability to different systems is analyzed in our recent work [20] . Figs.…”

Dataset for the new insights into methane hydrate inhibition with blends of vinyl lactam polymer and methanol, monoethylene glycol, or diethylene glycol as hybrid inhibitors

“…Air was removed from the free volume of the vessel by flushing with gaseous methane three times (we estimate the residual air content in the gas phase at 0.001–0.002 vol%). The three-phase gas–aqueous solution–hydrate equilibrium in the CH 4 –H 2 O–THI system was measured by the method described earlier [ 12 , 13 ]. Pressure and temperature of complete dissociation of methane hydrate at slow ramp heating (0.1 K/h) and simultaneous vigorous mixing of fluids (600 rpm) were taken as coordinates of the equilibrium point .…”

Dataset for the experimental study of dimethyl sulfoxide as a thermodynamic inhibitor of methane hydrate formation

“…The empty space of the vessel was purged thrice with gaseous methane. Measurements of hydrate equilibria were performed according to the technique previously analyzed in detail [6] . The validity of this technique has been confirmed for various systems with thermodynamic inhibitors such as DMSO [ 7 , 8 ], urea [9] , methanol [ 10 , 11 ], and glycols [12] .…”
