A nitrogen generator is an industrial system used to separate nitrogen from other gases in the ambient air, using a compressed air inlet, providing a varying flow and purity depending on the various applications.
Today, PSA and membrane systems are an appealing supply mode for a wide range of volumes, purities and applications. The former are based on adsorption, while the latter are based on selective permeation.
ABSOGER produces two types of nitrogen-generating technologies, in order to fully accommodate the client’s needs: PSA (Pressure Swing Adsorption) technology and membranes.
PSA technology
The PSA technology consists of separating the oxygen from the nitrogen contained in the ambient air at low pressure using a molecular sieve of activated carbons.
- PSA technology (Pressure Swing Adsorption): Adsorption by pressure variation.
- Need compressed air drying and purification
- 2-column generators with CMS activated carbon
- Continuous generation of stable, high-purity nitrogen.
- High purity levels (>99.9%).
