AADCO 441
Nitrogen Generators
Commercial nitrogen production (tank car quantities, cylinders, etc.) is usually conducted by cryogenic separation (liquefaction and rectification of air). Small scale preparation (for laboratory use) of high purity nitrogen is eco-nomically infeasible by this procedure.
AADCO nitrogen generators produce very pure nitrogen from pressurized air. This generation system relies upon an air source, which is constantly increasing in pressure during the separation cycle, i.e., no static or falling pressure during the cycle. The absorbing medium is able to retain oxygen, water and trace gases selectively while permitting uninterrupted passage of nitrogen and argon. The AADCO nitrogen generator output is actually 99% nitrogen and 1% argon, both inert. The product purity is equivalent to Research Grade Nitrogen (the very best grade), having a minimum purity of 99.999 mole%. It is usually supplied only in small cylinders from the gas cylinder bottlers. |
