ABSTRACT:
An improved liquid phase adsorption process is provided using a fixed bed system wherein the conventional post-regeneration bed-filling step and the post-adsorption bed-draining step are replaced by a displacement step. The bed volume of regeneration medium in a first bed of the system undergoing the final stage of regeneration cool-down is passed directly into a second bed of the system in the final stage of the adsorption step whereby the bed volume of void-space feedstock in said second bed is removed therefrom by displacement, thus effectively accomplishing in a single operation the filling step in the first bed and the draining step in the second bed.
