A process is described for the removal of sulfur compounds and water from a fluid stream feedstock comprising the steps of: (a) passing the fluid stream feedstock 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 water and removing a first adsorption effluent which is substantially free of sulfur compounds; (b) passing a regeneration medium through the outlet end of at least one primary adsorber which is on a regeneration mode and contains sulfur-laden and water-laden adsorbent under desorption conditions to regenerate the adsorbent and provide a regeneration effluent leaving the inlet end; (c) cooling the regeneration effluent, when the sulfur compound concentration has decreased to a substantially lower level, to condense water contained within the regeneration effluent and removing the condensed water to provide a treated regeneration effluent; (d) combining the treated regeneration effluent with fluid stream feedstock in step (a); (e) passing at least a portion of the second adsorption effluent from step (d), at least when the sulfur adsorption front breaks through the outlet end of the adsorber to cause an increase in the concentration of sulfur compounds; and (f) continuing the adsorption in step (d) until the adsorption effluent reaches a predetermined sulfur compound concentration value.
