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 ...

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
