Effects of Hydrophobic Silica on the Performance of Silicone-Based Antifoams [PDF]
Journal of Chemical and Petroleum Engineering, 2021 The efficiency of an antifoam consists of polydimethylsiloxane oil, hydrophobe silica particles, and either Sodium Dodecyl Sulfate (SDS) as an anionic surfactant, or Octyl phenyl deca ethylene oxide (Triton X-100) as nonionic surfactant for use in ...

Mixed adsorption and surface tension prediction of nonideal ternary surfactant systems [PDF]
, 2005 To deal with the mixed adsorption of nonideal ternary surfactant systems, the regular solution approximation for nonideal binary surfactant systems is extended and a pseudo-binary system treatment is also proposed.

Effect of Surfactant Additives on Phase Inversion in Oil-Water Pipe Flow System [PDF]
Engineering and Technology Journal, 2017 This research investigates the effect of surfactant additives on phase inversion point in the oil-water flow in horizontal pipe. Two types of surfactants were used in the experiments; anionic type (sodium lignosulfonate (SLS)) at 200 ppm and cationic ...

The influence of surfactants of different classes on the toxicity of diesel fuel for Saccharomycetes [PDF]
E3S Web of Conferences, 2023 The effect on the survival of the yeast S. cerevisiae of mixtures of diesel fuel (summer variety) with four representatives of different classes of surfactants – cationic (cetyltrimethylammonium bromide), anionic (sodium dodecyl sulfate), nonionic (Tween-

Journal of Colloid and Interface Science, 2020 Surfactant losses by adsorption to rock surfaces make surfactant-based enhanced oil recovery economically less feasible. We investigated polyacrylate (PA) as a sacrificial agent in the reduction of anionic surfactant adsorption with focus on calcite ...

Influence of liquid surface tension (surfactants) on bubble formation at rigid and flexible orifices [PDF]
, 2004 The influence of liquid surface tension on the bubble formation from both rigid and flexible orifice has been investigated. The liquid phases under test are aqueous solutions with butanol or surfactants (cationic, non-ionic and anionic); static and ...
