Abstract
A process for reducing the size of sulfur removal units is presented. The process includes passing a regeneration gas from a regenerated contaminant adsorption unit through a fixed bed adsorber. The fixed bed adsorber adsorbs sulfur compounds above an equilibrium condition and releases adsorbed sulfur compounds below the equilibrium condition. The peak levels of sulfur in the regeneration gas are reduced and the processing of the regeneration gas reduces the size of sulfur removal units.
