ABSTRACT:
A pressure swing adsorption (PSA) process is provided for the size-selective separation of a feedstream into an adsorbate fraction employing a rapid blowdown step to induce a state of disequilibrium within an adsorbent bed and thereby increase the weight hourly space velocity of the process. The selective separation mechanism explored in the PSA process may also include equilibrium separation. The benefits include a reduced adsorbent bed size for new installations or increased feed rates for existing facilities. In one aspect of the invention the feedstream to be separated comprises iso and normal pentane.
