De-Emulsification and Gravity Separation of Micro-Emulsion Produced with Enhanced Oil Recovery Chemicals Flooding

open access: yesEnergies, 2021
The present study investigates the effect of TiO2 nanoparticles on the stability of Enhanced Oil Recovery (EOR)-produced stable emulsion. The chemical precipitation method is used to synthesize TiO2 nanoparticles, and their properties were determined ...

Factors and Kinetics Related to the Formation of Heavy Oil-in-Water Emulsions

open access: yesEnergies, 2023
Oil-in-water emulsions provide an essential contribution to enhanced oil recovery by acting as oil displacement and conformance control systems. However, the dominant factors affecting their emulsification and kinetics are unclear.

Synthesis of magnetic nanoparticles (Fe3O4) coated with fatty acids and surfactants and their application in demulsification of crude oil and water emulsions [PDF]

open access: yesJournal of Applied Research in Water and Wastewater, 2023
Crude oil is released into the water sources during exploration, extraction or displacement operations due to the partial dissolution, and it can remain as a layer on the surface of the water or become emulsive.

Preparation of Multifunctional Surfactants Derived from Sodium Dodecylbenzene Sulfonate and Their Use in Oil-Field Chemistry

open access: yesMolecules, 2023
Four products were obtained from sodium dodecylbenzene sulfonate (SDBS) and formaldehyde (40% solution) using a simple reaction. The products were characterized by TGA, IR, UV and MS to confirm the major chemicals in each sample.

Mechanisms of burst release from pH-responsive polymeric microparticles. [PDF]

open access: yes, 2011
Microencapsulation of drugs into preformed polymers is commonly achieved through solvent evaporation techniques or spray drying. We compared these encapsulation methods in terms of controlled drug release properties of the prepared microparticles and ...

Effect of viscosities of dispersed and continuous phases in microchannel oil-in-water emulsification [PDF]

open access: yes, 2010
Although many aspects of microchannel emulsification have been covered in literature, one major uncharted area is the effect of viscosity of both phases on droplet size in the stable droplet generation regime. It is expected that for droplet formation to
