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: The present disclosure provides a process for reducing oxygenate content of hydrocarbon feed. The process comprises passing and heating the hydrocarbon feed over ion exchange resin resident in a reactor, maintained at a temperature in the range of 90 to 140° C. and a predetermined pressure, at a predetermined liquid hourly space velocity to obtain a heated intermediate fluid. The heated intermediate fluid is cooled to obtain a cooled intermediate fluid. The cooled intermediate fluid is mixed with water to obtain a mixture. The mixture is allowed to settle to obtain an aqueous phase and an organic phase. The aqueous phase is separated from the organic phase to obtain hydrocarbon feed with reduced oxygenate content. The process is simple and environment friendly, enabling removal of 70-90% of the oxygenate content from the hydrocarbon feed.

Abstract: The present disclosure relates to a process for reducing the amount of carbon disulphide (CS2) in a hydrocarbon feed containing C5-C8 fractions. The hydrocarbon feed is treated with an amine functionalized anion exchange resin (basic anion exchange resin) to obtain a mixture comprising a liquid fraction containing treated hydrocarbon and a solid mass containing an adduct of CS2 and the amine functionalized anion exchange resin. The so obtained liquid fraction containing the treated hydrocarbon is separated from the solid mass to obtain the hydrocarbon having CS2 content less than 2 ppm. The amine functionalized anion exchange resin can be regenerated from the solid mass.
