摘要:
A process and apparatus for separating gaseous mixtures by a pressure swing adsorption technique. One or more adsorbent beds are employed which operate on a cycle comprising the successive steps of adsorption, vacuum regeneration, and backfilling. The pressure in the bed(s) during backfilling is sensed, backfilling is ceased when such pressure reaches a predetermined level, and the regeneration step is controlled to occupy a constant period of time. The described process is able to maintain a substantially constant output flow and product purity despite the changes in adsorption capacity of the bed(s) which occur under fluctuating ambient temperatures.
