Energies, 2022 Surfactant flooding can mobilize trapped oil and change the wettability of the rock to be more hydrophilic, which increases the oil recovery factor. However, the selection of surfactants is difficult in the case of high salinity conditions. In this work,

Ionic behavior assessment of surface-active compounds from corn steep liquor by exchange resins [PDF]
, 2016 Depending on their ionic nature, biosurfactants can be classified as nonionic, anionic, cationic, or amphoteric. The ionic behavior of biosurfactants is an important characteristic that dictates their use in industrial applications.

Optimization of Oil-in-Water Emulsion Stability: Experimental Design, Multiple Light Scattering, and Acoustic Attenuation Spectroscopy [PDF]
, 2010 To find an optimal formulation of oil-in-water (O/W) emulsions (o = 0.05), the effect of emulsifier nature and concentration, agitation speed, emulsifying time, storage temperature and their mutual interactions on the properties and behavior of these ...

Pickering emulsions stabilized by hydrophilic nanoparticles: in situ surface modification by oil [PDF]
, 2016 We propose a novel route for the stabilization of oil-in-water Pickering emulsions using inherently hydrophilic nanoparticles. In the case of dialkyl adipate oils, in situ hydrophobisation of the particles by dissolved oil molecules in the aqueous phase ...

The Influence of Bicomponent Mixed Surfactants on Drop/Interface Coalescence [PDF]
Iranian Journal of Chemistry & Chemical Engineering, 2004 Effects of binary mixtures of ionic/nonionic (sodium dodecyl sulfate/2-heptanol or 1-decanol) and nonionic/nonionic surfactants (2-heptnol/1-decanol) on drop/interface coalescence of water drops in a continuous n-heptane phase were examined.

Crack Reduction during Drying Process by Using Surfactant [PDF]
MATEC Web of Conferences, 2019 In this research clay brick samples were made from illitic clays. Surfactant was added to clay mass during formation process to reduce crack generation during drying process.
