OverviewVariations of PSA technologyProcessAdsorbentsApplicationsSee alsoFurther reading(DS-PSA, sometimes also referred to as Dual Step PSA). With this variant of PSA developed for use in laboratory nitrogen generators, nitrogen gas is produced into two steps: in the first step, the compressed air is forced to pass through a carbon molecular sieve to produce nitrogen at a purity of approximately 98%; in the second step this nitrogen is forced to pass into a second carbon molecular sieve and the nitrogen gas reaches a final purity up to 99.999%. The purge gas from th…
