* Nitrogen Generator: Continually produces nitrogen from compressed air using a carbon molecular sieve, generating up to 1000 lit/min
Hi-line says the proven technology employed for N2/02 generation is based on simple PSA (Pressure Swing Adsorption) procedures--here, twin-tower CMS (carbon molecular sieve) beds adsorb and regenerate to remove either N2 or 02 depending on requirements and importantly, this allows users to generate nitrogen at the purity required for the application, such as 95% or 98% for example and this is far more cost-effective than buying-in expensive UHP (Ultra High Purity) nitrogen at 99.99999%, which is normally sold as standard without any option for the customer.
* Pressure swing adsorption (PSA) systems are vessels filled with a carbon molecular sieve that is pressurized with air.
The air then passes through two columns filled with proprietary carbon molecular sieve, which adsorb oxygen and carbon dioxide, moisture and hydrocarbons.
The air, which comprises about 78% nitrogen, is passed through a pre-filter and a carbon molecular sieve where oxygen and other components are adsorbed.

Consists of two filter beds of carbon molecular sieve. While preheated compressed air enters the bottom of the first bed and passes across the sieve, oxygen and trace gases are absorbed as nitrogen is allowed to pass through to enter a low-pressure storage tank.
In another hydrogen separation application, supported carbon molecular sieve membrane was studied to determine the selectivity and permeation properties for low molecular weight gases, presenting a competitive alternative in gas separation [23].
An integral carbon molecular sieve and residual moisture trap adsorb the remaining oxygen, leaving the dry nitrogen ready for immediate use.

Future investigations will include the addition of inorganic fillers as carbon molecular sieves; as well as zeolites that will further enhance the polymeric blended membrane.
