Solvent recovery from systems containing crude sesame seed oil and short-chain alcohols at different temperatures and local pressure

•Equilibrium data on sesame oil and alcohols were determined from 283.2 to 333.2 K.•Temperature-dependent binary interaction parameters of the NRTL model were adjusted.•From 6 to 36% of ethanol or isopropanol is found in the oil-rich phases.•Recovery close to 100% was reached for systems with azeotropic ethanol at 288.2 K.•Lower alcohol content (8%) was observed in the oil-rich phases from Et6 systems.
