Palm oil-based surfactants were used to formulate demulsifiers for crude oil demulsification as alternatives to petroleum-based surfactants. A light crude oil sample obtained from x field crude oil well contained 0.713% (w/w) asphaltene and 25.75% BS&W. The formulation of demulsifiers was carried out by the selection of a primary surfactant from Sodium Methyl Ester Sulfonate (SMES) and Diethanolamide (DEA), and the concentration of co-surfactant addition. The best formulation was SMES as a primary surfactant with the addition of a 10% DEA co-surfactant. The best solvent was the solution of toluene and xylene (1:1). The temperature treatment of 80 °C separated 100% water from crude oil emulsion and decreased BS&W to 5.45%.
