Double Stage Pressure Swing Adsorption (DS-PSA)
Nitrogen gas generation is divided into two steps: in the first step, the compressed air is forced to pass through a carbon molecular sieve to produces nitrogen at a purity of aprox 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 the second step is recycled and partially used as feed gas in the first step.
The N2-Sirocco model of Nitrogen Gas Generator have been designed for applications requesting larger flow and highest purity of Nitrogen. They use the Double Stage Pressure Swing Adsorption (DS-PSA) principle to produce high purity Nitrogen which eliminates the need for costly, inconvenient high pressure cylinders in laboratories. N2-Sirocco models include internal oil free compressors and …more
