Abstract
Methods for operating an adsorption separation zone are described. A trim bed is used with two adsorption beds in a swing bed arrangement. The trim bed will catch small amounts of treated feed remaining in the adsorption bed during the switch over from the spent adsorption bed to the fresh adsorption bed. In addition, any adsorbed material that desorbs from the spent adsorption bed during the displacement step of regeneration would be adsorbed onto the trim bed.
