The present disclosure relates to a process for reducing the amount of carbon disulphide (CS) in a hydrocarbon feed containing C-Cfractions. 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 CSand 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 CScontent less than 2 ppm. The amine functionalized anion exchange resin can be regenerated from the solid mass.

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.

The present disclosure provides a process for obtaining extracted crude oil (ECO) which is substantially free of naphthenic acids, calcium and other impurities from low asphaltic crude oils or their residue fractions by preferential extraction of saturates using at least one solvent.
