Patent ID: 7452459

Claim:
A process for the removal of sulfur-oxidated compounds from a hydrocarbonaceous stream containing sulfur-oxidated compounds wherein the process comprises: (a) contacting a hydrocarbonaceous stream containing sulfur-oxidated compounds with an adsorbent which selectively adsorbs sulfur-oxidated compounds to produce an adsorbent having adsorbed sulfur-oxidated compounds; (b) contacting the adsorbent having adsorbed sulfur-oxidated compounds with a desorbent to produce a desorbent containing sulfur-oxidated compounds and an adsorbent having a reduced content of sulfur-oxidated compounds; (c) introducing desorbent containing sulfur-oxidated compounds from step (b) into a high sulfur, lower end zone of a split shell fractionation column; (d) contacting the adsorbent from step (b) with a hydrocarbonaceous stream containing sulfur-oxidated compounds; (e) introducing an initial portion of an effluent from step (c) comprising desorbent from step (b) into a low sulfur, lower end zone of said split shell fractionation column, (f) fractionating the desorbent containing sulfur-oxidated compounds from step (b) to recover a desorbent having a reduced concentration of sulfur-oxidated compounds; and (g) recovering a hydrocarbonaceous stream containing a reduced concentration of sulfur-oxidated compounds.
