What is nitrogen used for from air separation perspective？

The molecular structure of nitrogen is so stable that it is usually very difficult to react chemically with other substances and shows great inertness, so it is often used as a protective gas in industry.

1. Nitrogen-filled storage of fruits and vegetables is an advanced method of storage and preservation, which allows fruits and vegetables to slow down their metabolism in an environment of high nitrogen and low oxygen, and to enter a state of hibernation and inhibit post-ripening, thus preserving freshness for a long time.
2. "Vacuum filled with nitrogen" for storing rice and other grains, which can make the grain away from moths, heat and mould.
3. nitrogen is one of the important nutrients for plant growth, the nitrogen in the air is difficult to be absorbed by plants directly, people generally through the production of synthetic ammonia, and then use ammonia as raw material, the production of seed preparation can be absorbed by plants nitrogen fertilizer, such as urea.
4. Pure nitrogen is mainly used in oilfield nitrogen injection, petrochemicals, synthetic fibres, synthetic ammonia, float glass, steel rolling and the electronics industry.

For different requirements of the product, some require an uninterrupted supply of product, some need spare liquid nitrogen, Dear Air Separation has extensive experience in production, design, technology, design and its appropriate nitrogen production process, the equipment meets market demand.
