Product Description
Nitrogen Purification Manufacturing Plant (NP-C)

Nitrogen purification equipment

Plus Hydrogen eliminate Oxygen making Nitrogen purity equipment


O2+H2- - H2O

Via Oxygen and Hydrogen can make water under the catalyzator function, Plus the Hydrogen into Nitrogen, the mixed gas will make reaction in the oxygen eliminating equipment which will full of high efficiency catalyzator, to eliminate oxygen etc impurity, absorbing the double time dry principle to eliminate water, getting the high purity Nitrogen. Catalyzator will be the crucial part during the whole eliminating oxygen process, while palladium etc noble metal is the key in catalyzator, therefore we also called catalyzator for palladium catalyzator. Also called Palladium catalyst.


1. The gas contain excessive Hydrogen, quite suitable for reduction gas application, the hydrogen content can be controlled
2. Simply principle, perfect structure, low power consumption
3. Stable gas index, lower impurity
4. Automatic system alternatively, without people working on duty.
5. Widely application, no special requirements to raw material gas.
