DP-001NPNitrogen purificationsystem

Introduction:

This purifing unit is used fornitrogen purification at various pressure levels. This unit usesthe normal nitrogen (purity above 98%) as the feed material,through palladium(PD) catalyst or carbon deoxidant, it removes theoxygen and then removes the moisture through the drier. Theprocessing 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 theuser’s needs.

Workprinciple

(with palladiumcatalyst)  

The normal nitrogen with acertain flow rate and purity enters into the unit with the hydrogenat the same time, after being fully mixed in the mixer, the mixedgas enters into deoxygenation unit filled with palladium catalyst.With the function of deoxo catalyst, the chemical reaction happensto remove the oxygen.The moisture inside the deoxygenated nitrogenwill be removed through the cooler. The nitrogen gas then entersinto the driers to inrease its dew point up to -60C°.Two driers areequiped: one is for adsorption dring and the other is to regeneratethe first dreier which has fully adsorbed the moisture to get readyfor the next period adsoption. Finally, the high purity product isobtained after removing the dust from the dried nitrogen inside thefilter.

(Removing oxygen bycarbon catalyst)

Flow Rate: 1Nm³/h ~ 3000Nm³/h

Purity:≥99.9995%

Pressure:≤0.8Mpa

Dew Point:≤-70C

Oxygen Content:≤5ppm

CO2:≤5ppm

C O2 Carbon deoxidant CO2-O(heat relief)

Workprinciple:

( With carbondeoxygenation)

With the function of the carboncatalyst,the oxygen inside the nitrogen is removed through thechemical reaction of the oxygen remains and the carbon supplied bythe carbon catalyst.Then the moistur remains and CO2 in thedeoxygenated nitrogen are removed through the cooler and the drier,meanwhile, the dew point of the nitrogen reaches about -60C°. Twodriers are equiped: one is for adsorption dring and the other is toregenerate the first dreier which has fully adsorbed the moistureto get ready for the next period adsoption. Finally, the highpurity product is obtained after removing the dust from the driednitrogen inside the filter.

Features:

1). LowCost: Removing oxygen with catalyst is a simple and easy processwith low energy consumption and compact equipment structure. Theoperation cost is much lower than other metheds of producing highpurity nitrogen.

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

3).High Purity: The moleculeoxygen and moisture contents are supervised by the instruments toguarantee the needed nitrogen purity.

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