1. Metallurgical, mechanical, and electronic industries:

Using nitrogen for dry quenching of coke is one of the major energy-saving measures in steel plants. For every ton of coke quenched, about 1500m3 of nitrogen needs to be circulated, and 25 tons of coke can be quenched per hour, providing approximately 2000-3000KW of electricity.

Directly spraying desulfurizer into the molten iron with nitrogen gas in the ladle has a good desulfurization effect.

Metal heat treatment, nitrogen protected bright annealing. Nitrogen protection for metal powder sintering. Quenching, gas carburizing, etc.

Nitrogen protection for electronic device manufacturing and production lines.

2. Chemical and petrochemical industries:

Nitrogen is the raw material gas for producing synthetic nitrogen and urea, and 600m3 of nitrogen is required to produce one ton of lime fertilizer.

Nitrogen is mainly used as a protective gas, displacement gas, and scrubbing gas in chemical plants to ensure safe production. For the production of polypropylene, pure nitrogen transportation is required; Synthetic fiber drawing should be filled with nitrogen to prevent oxidation; Forestry chemical plants use nitrogen as a protective gas for the production process of sensitive adhesive coatings, rosin, resins, etc; Nitrogen is the 'protective gas' for chemical plants. Nitrogen is also used for the conversion and cleaning of oil storage tanks, containers, and pipelines. Purification of oxygen emissions from oil tankers and offshore platform pipelines. Rubber packaging and tire production protection, etc.

3. Pharmaceutical and food industries:

Pharmaceutical raw materials, nitrogen filled packaging and transportation of drugs.

The nitrogen filling method for storing fruits, vegetables, rice, tea, dried fruits, seeds, Chinese herbal medicines can maintain their original color, aroma, taste style, and rich, strong, fresh taste, as well as the quality of storage. Its quality is significantly better than mechanical refrigeration.

Carbon molecular sieves and zeolite molecular sieves are commonly used in the fields of nitrogen and oxygen production. The separation of oxygen and nitrogen by molecular sieves is mainly based on the different diffusion rates of these two gases on the surface of the molecular sieve. Carbon molecular sieve is a carbon based adsorbent that combines certain characteristics of activated carbon and molecular sieve. Carbon molecular sieves have a very small microporous composition, with pore sizes ranging from 0.3nm to 1nm. Smaller diameter gases (oxygen) diffuse faster and enter the solid phase of the molecular sieve more, allowing for the enrichment of nitrogen components in the gas phase.

The method of using air as raw material, carbon molecular sieve as adsorbent, and pressure swing adsorption principle to selectively adsorb oxygen and nitrogen by carbon molecular sieve to separate nitrogen and oxygen is commonly known as PSA nitrogen production. This method is a new nitrogen production technology that rapidly developed in the 1970s.
