INCREASING SCALES, CAPACITIES, AND/OR EFFICIENCIES IN SWING ADSORPTION PROCESSES WITH ROTATING ADSORPTION MODULES

摘要

The invention relates to an increased efficiency high-capacity pressure and/or temperature swing adsorption process comprising: contacting a feedstream at a rate of more than 75 MSCFD with an adsorbent material under conditions sufficient for the adsorbent material to selectively adsorb at least one of the component gases in the feedstream, so as to form a first effluent; and selectively desorbing the adsorbed gas from the adsorption material, so as to form a second effluent. The adsorption module contains rotary valves both on the feed end and on the product end and a rotational member defining a central rotational axis, with the adsorption bed(s) oriented circumferentially thereto. The adsorption bed walls are angled and/or the feed end cross-sectional area of the adsorption bed(s) is larger than the product end and/or the feed end rotary valve diameter of the module(s) is larger than the product end.
