Separation of oil-soluble sulfonates from sulfonated oils
The authors aimed at developing a method for the complete recovery, from oil solutions, of oil-water-soluble sulfonates meeting the specifications, along with oils at least 99% pure, suitable for further processing. As the starting material the authors used an experimental batch of sulfonated and neutralized distillate lube stocks produced by selective solvent treatment. In determining the optimal extraction parameters, the authors investigated the influence of the solvent to original feed (S:F) weight ratio and the influence of the isopropyl alcohol (IPA) concentration on the composition of the sulfonates and oils recovered at 60/sup 0/C with a settling time of 2 h. The optimal conditions for two-stage extraction were found through a study of the influence of temperature and settling time on the compositions of the sulfonates and oils with S:F = 1.2:1 and with an IPA concentration of 40%. The process technology for two-stage recovery of oils and sulfonates from oil solutions was worked out in a pilot unit.
