  • Guard layers for rapid cycle pressure swing adsorption devices
    Patent number: 8303683
    Abstract: Guard layers are employed in the adsorbent beds of rapid cycle pressure swing adsorption (RCPSA) devices to protect the adsorbent therein from certain contaminants (e.g. water vapour). Conventional PSA devices typically pack the guard layer with as much guard material as is practical. In RCPSA devices however, the performance of the guard layer can be improved by using a reduced amount of guard material and increasing access to it. Such embodiments are characterized by guard layers with a channel fraction of greater than 50%.
    Type: Grant
