This patent describes a process for the removal of sulfur compounds from a fluid stream feedstock comprising the steps of: (a) passing the fluid stream through an inlet end of at least one primary adsorber which is on an adsorption mode containing adsorbent selective for the adsorption of sulfur compounds and removing and adsorption effluent; (b) passing a portion of the adsorption effluent, as a regeneration medium, through the outlet end of at least one primary adsorber which is on a regeneration mode and contains sulfur-laden adsorbent under desorption conditions; (c) passing the regeneration effluent, when the sulfur compound concentration has decreased to a substantially lower level, to at least one auxiliary sorber containing sorbent selective for the sorption of sulfur compounds in the regeneration effluent to provide a treated regeneration effluent being substantially free of sulfur compounds; (d) passing the adsorption effluent from step (a) through at least one auxiliary sorber containing sorbent selective for the sorption of sulfur compounds in the regeneration effluent when the adsorption front breaks through the outlet end of the adsorber to cause an increase in the concentration of sulfur compounds in the adsorption effluent, to provide a treated adsorption effluent being substantially free of sulfur compounds, and continuing the adsorption in step (a) until the adsorption effluent reaches a predetermined sulfur compound concentration value.
