Nitrogen Purification System

Principle

O2 + C ----- CO2

O2 and palladium carbon catalyst will produce CO2 in catalytic reaction, the remaining O2 in N2 is eliminated in deoxygen tank filled with high performance palladium carbon catalyst to remove oxygen impurities, and then after double steps removing moisture by cooling and adsorption, to obtain high purity N2 (99.9995%). Deoxidization of the core components is the palladium carbon catalyst.

Introduction

O2 + H2 ----- H2O

O2 and H2 will produce H2O when heating in catalyst, Add some H2 in N2, the mixed air will chemical reaction in de-oxygen tank filled with catalyst to remove the oxygen impurities. and then after double steps removing moisture by cooling and adsorption, to obtain high purity nitrogen(99.9995%).

Features

● Does NOT contain any H2 in outlet N2, suitable for production processing that requires hydrogen free atmosphere.

● Simple operation, compact structure, low energy cost

● Continuous monitoring purity, temperature, O2 content and other specifications, stable to maintain high purity N2.

● Automatic system optional, no workers needed for operation.

● Wide range of applications, no special requirements for raw material air.



● The gas contains hydrogen gas, quite suitable for gas atmosphere needs H2, the hydrogen content can be controlled.

● Simply operation, compact structure, low energy cost.

● Continuous monitoring purity, temperature, O2 content and other specifications, stable to maintain high purity nitrogen gas.

● Automatic system optional, no workers needed to operation.

● Widely range of application, no special requirements for raw material air.


Technical Index

Nitrogen Gas:

● Pressure —— 0.6~0.7Mpa

● Dew Point —— ≤-40℃

● Oxygen Content —— ≤1%

● Capacity —— 5~5000Nm3/h High Purity Nitrogen Gas:

● Pressure —— 0.5~0.6Mpa (Ajustable)

● Dew Point —— ≤-70℃

● O2 Content —— ≤3ppm

● H2 Content —— None

● Capacity —— 5~5000Nm3/hr

● Note: Higher standard for O2 content and dew point, can equip with multistep moisture-remover. And considering the less consumption for palladium carbon catalyst, which is of course lower cost, we suggest customer to use the O2 ≤0.1% of the nitrogen gas.
