Cyclopentane hydrate
Web1.Introduction. Hydrates are gradually playing an important role in preventing energy shortages and environmental protection, and are wildly stored on the seafloor [1], [2].Hydrate reservoir exploitation methods mostly include depressurization [3], thermal stimulation [4], chemical regent [5], CO 2 replacement [6], and solid fluidization method … WebThis work presents the adsorption of an anionic surfactant, sodium dodecyl sulfate (SDS), and a cationic one, dodecyl-trimethylammonium bromide (DTAB), on cyclopentane (CP) hydrates. Adsorption isotherms were obtained by liquid−liquid titrations. Also, the adsorption was qualitatively studied by zeta potential measurements. The isotherm of both SDS and …
