摘要

Process for the separation of a gas adsorvu00ecvel a gas mixture comprising the gas adsorvu00ecvel and a gas adsorvu00ecvel in an area of adsorption by oscillation of the pressure. A process that overcomes the limitations to the ability of PSA units for a wide variety of separations of gases reaching capacities in excess of about 110 thousand cubic meters to normal byTime in a single train of integrated process and away from the practice of using a purge step equal to or less than the period of the step of adsorption.Increasing the purging time relative to the step of adsorption combination combined with the supply of purge gas to a bed of adsorption on the train of one or more other adsorption beds and DuDuring the step of providing purge,The other beds adsorbents simultaneously provide the purge gas to essentially all the beds adsorbents through purge step, and the train only can ensure significant increases inThe capacity with minimal loss in recovery or performance.
