Application of Nitrogen in cable industry - Nitrogen Generator
In the cross-linked insulated wires and cables, the main cross-linking methods are inert gas (nitrogen) cross-linking, warm water cross-linking and irradiation cross-linking. For the production of 10-500kV cables with large cross section and high voltage level of more than 70mm2, it is mainly realized by inert gas cross-linking (dry chemical cross-linking). Inert gas cross-linking using polyethylene insulation material with peroxy compound cross-linking agent, through three layers of co-extrusion to complete the extrusion of conductor shielding layer - insulation layer - insulation shielding layer, continuous and uniform through the sealed cross-linking tube filled with high temperature, high pressure nitrogen to complete the cross-linking process. Heat transfer media for nitrogen (inert gas), crosslinked polyethylene electrical performance is excellent, production range up to 500KV class.

PSA Nitrogen Generator  full name: Pressure Swing Adsorption (PSA).PSA is a new gas separation technology, which has been developed rapidly in foreign countries since the late 1960s and early 1970s. Its principle is to separate the gas mixture by the difference of the "adsorption" performance of different gas molecules by molecular sieve. It takes air as raw material.The nitrogen and oxygen in the air are separated by the selective adsorption of nitrogen and oxygen with a high efficiency and high selection of solid adsorbent.

At present, carbon molecular sieves and zeolite molecular sieves are used more in the field of nitrogen and oxygen production.The separation of oxygen and nitrogen by molecular sieve is mainly based on the different diffusion rates of the two gases on the surface of molecular sieve. Carbon molecular sieve is a carbon-based adsorbent with some characteristics of activated carbon and molecular sieve.Carbon molecular sieves are composed of very small micropores with pore sizes ranging from 0.3nm to 1nm.The smaller diameter of the gas (oxygen) diffuses faster and more into the solid phase of the molecular sieve, so that nitrogen enrichment can be obtained in the gas phase.After a period of time, molecular sieve on oxygen adsorption balance, according to the carbon molecular sieve under different pressure on the adsorption of different gas adsorption characteristics, reduce the pressure to remove the carbon molecular sieve on oxygen adsorption, this process is called regeneration.PSA usually uses two towers in parallel, alternately pressurized adsorption and decompression regeneration to obtain a continuous flow of nitrogen.

With air as raw material, with carbon molecular sieve as adsorbent, the use of pressure change adsorption principle, the use of carbon molecular sieve on oxygen and nitrogen selective adsorption and separation of nitrogen and oxygen method, commonly known as PSA nitrogen.This method is a new technology of nitrogen production which developed rapidly in 1970s.Compared with the traditional method of nitrogen, it has simple process, high degree of automation, produce gas quickly (15 ~ 30 minutes), low energy consumption, product purity can be adjusted according to user needs in a wide range, convenient operation and maintenance, low operating cost, good adaptability device etc., in 1000 nm3 / h the following competitive in nitrogen making equipment,PSA is more and more popular among medium and small nitrogen users, and has become the choice method for medium and small nitrogen users.

1. Why choose PSA nitrogen generator ?
High  purity
PSA nitrogen generator plants allow production of high-purity nitrogen from air, which membrane systems are unable to provide - up to 99.9995% nitrogen.The nitrogen generators use CMS (carbon molecular sieve) technology to produce a continuous supply of ultra high purity nitrogen and are available with internal compressors or without.
Low operating costs
By substitution of out-of-date air separation plants nitrogen production savings largely exceed 50%. 
The net cost of nitrogen produced by nitrogen generators is significantly less than the cost of bottled or liquefied nitrogen.
Nitrogen Generators Create Less Impact on the Environment
Generating nitrogen gas is a sustainable, environmentally friendly and energy efficient approach to providing pure, clean, dry nitrogen gas. Compared to the energy needed for a cryogenic air separation plant and the energy needed to transport the liquid nitrogen from the plant to the facility, generated nitrogen consumes less energy and creates far fewer greenhouse gases.

LDHGAS psa nitrogen making machine process and equipment introduction
1. The technological process of nitrogen generator is briefly introduced
Air through the air filter to remove dust and mechanical impurities into the air compressor, compressed to the required pressure, after strict oil removal, water removal, dust removal and purification treatment, output clean compressed air, the purpose is to ensure the service life of the molecular sieve. At work, one pot adsorption, the other pot desorption, two sub work alternately. Clean air into the working adsorption tower, through molecular sieve oxygen, carbon dioxide and water absorption, flow to the outlet end of the gas is nitrogen and trace argon and oxygen. In this way, the two towers take turns to separate nitrogen and oxygen and continuously output nitrogen. The purity of nitrogen produced by psa is 95% to 99.999%.
