 DP-001NP Nitrogen purification system

Introduction:

This purifing unit is used for nitrogen purification at various pressure levels. This unit uses the normal nitrogen (purity above 98%) as the feed material, through palladium(PD) catalyst or carbon deoxidant, it removes the oxygen and then removes the moisture through the drier. The processing capacity could be designed from 1Nm³/h to 3000 Nm³/h, the outlet pressure could be set from 0.05Mpa to 0.7Mpa as per the user’s needs.

Technical data:

Dew Point:≤-70C°

Oxygen Content:≤5ppm

Hydrogen Content:≤5ppm

H2+O2 Palladium catalyst H2O+O(heat relief)

Work principle

(with palladium catalyst)  

The normal nitrogen with a certain flow rate and purity enters into the unit with the hydrogen at the same time, after being fully mixed in the mixer, the mixed gas enters into deoxygenation unit filled with palladium catalyst. With the function of deoxo catalyst, the chemical reaction happens to remove the oxygen.The moisture inside the deoxygenated nitrogen will be removed through the cooler. The nitrogen gas then enters into the driers to inrease its dew point up to -60C°.Two driers are equiped: one is for adsorption dring and the other is to regenerate the first dreier which has fully adsorbed the moisture to get ready for the next period adsoption. Finally, the high purity product is obtained after removing the dust from the dried nitrogen inside the filter.

Technical data:

(Removing oxygen by carbon catalyst)

Flow Rate: 1Nm³/h ~ 3000 Nm³/h

Purity:≥99.9995%

Pressure:≤0.8Mpa

Dew Point:≤-70C

Oxygen Content:≤5ppm

CO2:≤5ppm

C+O2 Carbon deoxidant  CO2-O(heat relief)

Work principle:

( With carbon deoxygenation)

With the function of the carbon catalyst,the oxygen inside the nitrogen is removed through the chemical reaction of the oxygen remains and the carbon supplied by the carbon catalyst.Then the moistur remains and CO2 in the deoxygenated nitrogen are removed through the cooler and the drier, meanwhile, the dew point of the nitrogen reaches about -60C°. Two driers are equiped: one is for adsorption dring and the other is to regenerate the first dreier which has fully adsorbed the moisture to get ready for the next period adsoption. Finally, the high purity product is obtained after removing the dust from the dried nitrogen inside the filter.

Features:

1). Low Cost: Removing oxygen with catalyst is a simple and easy process with low energy consumption and compact equipment structure. The operation cost is much lower than other metheds of producing high purity nitrogen.

2).Reliable Performance: Due to the continuous deoxygenation, it’s unnecessary to regenerate the palladium catalyst and its life of use could be above 5 years. The automatic micro-thermal regeneration consumes much lesser energy, which ensures the continuous gas production.

3).High Purity: The molecule oxygen and moisture contents are supervised by the instruments to guarantee the needed nitrogen purity.

4).High Quality Pneumatic Valves: The imported high quality valves are controlled by the PLC to guarantee the stable operation of the equipment.
