Abstract
A single bed pressure swing adsorption process with at least one transfer tank is utilized to separate less adsorbable components from more adsorbable components such as the separation of oxygen from air. Depressurization gas is collected in the transfer tank and is used later exclusively for purging the bed during the regeneration period.
