The removal of thermally aged films of triacylglycerides by surfactant solutions [PDF]
, 2013 Thermal ageing of triacylglycerides (TAG) at high temperatures produces films which resist removal using aqueous surfactant solutions. We used a mass loss method to investigate the removal of thermally aged TAG films from hard surfaces using aqueous ...

Removal of chromium (III) by two-aqueous phases extraction [PDF]
, 2009 Two-aqueous phase extraction of chromium (III) as a solute from their aqueous solutions was investigated using polyethoxylated alcohols (CiEj) as a biodegradable non-ionic surfactant in the presence of anionic sodium dodecylbenzene sulfonate (SDBS ...

Surfactant-Assisted Assembly of Dipeptide Forming a Broom-like Structure
Molecules, 2022 Understanding the influence of surfactants on the assembly of peptides has a considerable practical motivation. In this paper, we systematically study the anionic surfactant-assisted assembly of diphenylalanine (FF).

Surfactant evaluation for enhanced oil recovery: Phase behavior and interfacial tension
Open Chemistry, 2022 Surfactant flooding is one of the successful techniques employed in enhanced oil recovery (EOR) to extract the remaining original oil in place after primary and secondary recoveries are performed. Selection of the right EOR surfactant is an important but

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 ...

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 ...

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 ...
