Abstract
PSA process for the separation of nitrogen from a gaseous mixture containing nitrogen by selective adsorption of nitrogen from the gaseous mixture in an adsorbent mass with cyclic pressure variations. At least one nitrogen adsorption phase is carried out at high pressure and at least one nitrogen desorption phase is carried out at low pressure. The adsorbent mass is arranged in a rotating adsorber and at least 50% of the adsorbent mass is constituted by a zeolite exchanged with lithium by more than 50%.
