Study of hydrate formation in water-in-waxy oil emulsions considering heat transfer and mass transfer

Experimental study of growth kinetics of CO2 hydrates and multiphase flow properties of slurries in high pressure flow systems

“…Nowadays, ow loops are considered as one of the most useful equipment for hydrate research, where a series of hydrate formation/decomposition, hydrate slurry ow and plugging experiments can be conducted. 2,[17][18][19][20][21] A large number of experimental data were obtained, which could simulate the real pipe ow and provide important reference for the elds. Melchuna et al 22 analyzed the inuence of the ow characteristics of the slurry and the crystallization process of methane hydrate in the emulsion system with different water content using a ow loop.…”

Effect of the Ethylene Vinyl Acetate Copolymer on the Induction of Cyclopentane Hydrate in a Water-in-Waxy Oil Emulsion System

“…Hydrate formation in the w/o emulsion is strongly influenced by oil–water interfacial properties. , The variation of induction time as depicted in Figures – could be due to the synergetic effect between wax crystals (with and without EVA) and the surfactant at the interface. Figure provides a series of interfacial tension results of oil phase (D130 oil and cyclopentane)–deionized water.…”

“…Zheng et al 45 found that wax can restrict the induction and formation of CO 2 hydrate in a water-in-oil emulsion (Oil phase -10# diesel). Liu et al 46 illustrated that wax can adsorb at the oil and water interface, affecting the structure of the hydrate shell and inhibiting the mass transfer.…”

Oil wells hydrate formation regularities

“…As follows from [11], deposits are sparingly soluble in petroleum solvents (gasoline, kerosene, diesel fuel, etc.) due to the high content of refractory paraffins.…”
