CANGAS Systems Company Limited | Updated: Aug 27, 2015

The Use of Nitrogen in Different Industries

1. Metallurgy

Used for annealing shielding gas, nitriding,slugging and purging gas. Some industries need nitrogen owning over 99.5% fineness, some require high-quality nitrogen having over 99.995% fineness or below -65℃ dew point.

 2. Chemistry and New Material

Mainly used for chemical material, pipe purging,atmosphere replacement, atmosphere protection, production delivery and etc. Some chemical industries do not require too much fineness, 98% is enough for some of them.

3.Food and Medican Industry

Mainly used for food packaging, food preservation, medical package, medical gas replacement and medical gas delivery.In usual case, the nitrogen has to undergo degerming, dedusting and dewatering to satisfy special requirements of this industry. Most companies of food industries just require nitrogen having over 98% fineness. Medical industries always require nitrogen having over 99.9% nitrogen. When the needed amount of nitrogen is little,membrane separation is applied. While needing large amount of nitrogen, PSA is used.

4.Elecrtricity Industries

Used for the sealings,sintering,annealing,reduction and storage of electricity equipments. The industries include wave-soldering, reflow soldering, crystal,piezoe-electric, electronic ceramics, electronic copper strip,battery, electron. Electricity industries always require high-quality nitrogen(fineness should be over 99.9% or 99.99%)

 5. Other Fields

Apart from the above industries,  the nitrogen generator is widely used in coal, petroleum and other industries. Along with the advanced technique and development of the society, the nitrogen is more and more widely used. The nitrogen generator has already replaced liquid nitrogen evaporator and bottling nitrogen for its low investment, low cost and convenience.
