Abstract: The present disclosure relates to a method for regeneration of spent ion exchange resins to obtain regenerated ion-exchange resins. The regenerated ion exchange resins can efficiently reduce the total acid number (TAN) of highly acidic crude oils. The present disclosure particularly relates to a method of treatment of spent ion exchange resins using at least one non-acidic crude oil condensate and at least one polar organic solvent.

Abstract: In the present disclosure there is provided a process for obtaining di-sulfide oil having sodium level below 0.1 ppm wherein a stream comprising di-sulfide oil having sodium level 1 ppm, collected as a waste stream from LPG desulfurization unit, is passed through an alumina bed packed in a column at a pre-determined liquid hourly space velocity (LHSV) and at pre-determined temperature to obtain a treated stream comprising di-sulfide oil having sodium level below 0.1 ppm.
