In petroleum research understanding displacement, redistribution, and adsorption of oil and water plays an important role. To study complex multi-component systems such as liquid/liquid/mineral interactions in the porous space of clays and shales we applied low field (2 – 15 MHz) and high resolution (300 MHz) NMR spectroscopy. The detailed NMR analysis shows that the results from low field NMR ...
The displacement flow of an organic Newtonian fluid by a pure viscoelastic aqueous solution is experimentally investigated inside circular microchannel 200 μm. Displacement commonly encountered in many industrial applications, from cleaning and decontamination to enhanced oil recovery. In this study, with no shear-thinning properties (known as Boger fluid) made up polyethylene oxide, glycol, zi...
Ion-exchange displacement chromatography has been adapted to centrifugal partition chromatography. The use of an ionic liquid, benzalkonium chloride, as a strong anion-exchanger has proven to be efficient for the preparative separation of phenolic acid regioisomers. Multigram quantities of a mixture of three hydroxycinnamic acid isomers were separated using iodide as a displacer. The displaceme...
To consider effective countermeasures against groundwater contaminated with dense non-aqueous phase liquids (DNAPLs) such as chlorinated solvents, it is first important to understand the mechanism of their migration in heterogeneous aquifer. In addition, numerical analysis models to simulate such a complex migration in heterogeneous aquifer are required. The displacement pressure, which is a mi...
