Various usages of gas argon in all kinds of industries

1.Used for arc welding (cutting), magnesium, aluminum, stainless steel and other alloy protective gas
2.It is used in the smelting of steel,aluminum,titanium and zirconium.
3.When argon discharging, there will be a purple glow , and used for lighting technology and fill the fluorescent lamp, photocell, lighting tube etc
4.In the process of wine-making, filler of beer barrels , which can put the oxygen plant displacement, in order to avoid raw materials in the barrel will be oxidized to acetic acid.
5.Heat treatment process is used to instead of nitrogen and ammonia, its effect beyonds nitrogen and ammonia, stainless steel heat treatment using argon protection when bending ,it is not easy to break.

Nitrogen—Industry salt

1.Nitrogen-filled packaging, nitrogen filling bulbs.Chemical properties (using chemical properties is stable, normal temperature is very difficult to react with other material “) food, canned, fruit and etc.usually use nitrogen for corrosion protection.The nitrogen filling in a light bulb, can prevent the tungsten oxide and slow down the utilization rate of tungsten filament, prolong the bulb’s service life .
2.Chemical synthesis is important raw materials of synthetic fiber (nylon, acrylic), synthetic resin, synthetic rubber and other , also can produce fertilizer.
3.Production car tyres, nitrogen filling tyre can improve the stability and comfort during driving, preventing blowout and grinding line due to deficency , prolong the service life of tires, reduce fuel consumption, protect the environment.
4.Used as shielding gas, normally, Nitrogen’s chemical nature doesn’t very lively, so it is often used as shielding gas.When welding metal with nitrogen,it can protect metal to keep it from oxidation.
5.Nitrogen can be used to protect historical and cultural relics. In the museum, often use to save some valuable and rare page, with gas cylinder full of nitrogen which make the moth smothered.

Various usages of gas oxygen in all kinds of industries

• Metal welding, cutting and a variety ofcombustion-supporting gas for combustion systemand some oxidizing gas technical process gas, etc.
• Metallurgical industry, including steel, non-ferrous metal smelting process, all have extensive use of oxygen, it is obviouslystrengthening smelting processand increase energy efficiency.
• Machinery industry: metal welding, cutting can greatly improve the working efficiency
• Chemical industry: manufacturing pharmaceutical, dyestuff, explosives and other chemical products, in addition to strengthen the production (such as the production of yellow phosphorus by oxygen blowing method, spray oxygen carrier coal, etc.)
• Electronic industry: except for combustion-supporting gas or gas oxide semiconductor integrated circuit,oxygenis one of the indispensable high purity gases in the line.Additionally, it is the important raw material of gas optical fiber
• It is used widely in national defense : the largest amount is rocket.
• Other applications: oxygen as oxidant available for MHD power generation oxygen plant ;Use oxygen to purify sewage,  using oxygen in mining for deep well operations;Using oxygen to deep sea fishing, diving;Use oxygen rescue choking patient, dyingpatient;Using oxygen for health care (such as highland mountaineers, geological workers, border patrol soldiers and other special groups’ using and general staff stay in oxygen bar, etc.)

Application of gas hydrogen in petroleum industry

It need to add hydrogenation and by de-sulfur and hydrogenation cracking to extract crude oil, petroleum refining process need to add hydrodesulfurizer.
The amount of hydrogen used in the petroleum industry is second only to synthetic ammonia. Hydrogen is mainly used for naphtha hydrodesulfurization, gas oil hydrodesulfurization, fuel oil hydrodesulfurization, improved flame height and hydrocracking of aircraft fuels, etc field. Hydrogen is mainly used for C3 fractions hydrogenation, gasoline hydrogenation C6-C8 fraction hydrodealkylation and the production of cyclohexane and so on.
Welcome to Suzhou Xinglu Air Separation Plant Science and Technology Development , Ltd. which focus on gas air separation plant,liquid air separation plant and so on.

Application of gas hydrogen in petrochemical industry

1) A 1000t/d scale ammonia plant is used as a raw material gas for ammonia, methanol and petroleum refining. It need 336 cubic meters for per ton of ammonia, and if the ammonia is produced on a large scale. The main cost is comes from the hydrogen.
A 2500t/d scale methanol plant, each production of 1 ton of methanol needs hydrogen 560 cubic meters;
Hydrogen is also the organic hydrogenation reaction feed gas.
2) Synthesis of organic compounds
Hydrogen and carbon monoxide synthesis compounds  to a variety of organic compounds , such as ethylene glycol synthesis, synthesis of polymethanes, alcohol homologous reaction,etc.

Application of carbon dioxide in chemical industry

1. Organic chemical industry

Carbon dioxide is used in organic chemical synthesis, can produce a variety of commonly used chemical products, such as urea, salicylic acid, etc.; Carbon dioxide function as monomer raw materials in the bimetallic coordination PBM-type catalyst, was activated to a higher degree, having copolymerization with the ring Oxide and format to PPC. After the treatment, the carbon dioxide resin material shall be got; Carbon dioxide can be used for blowing agent in the plastic industry, .

2. Fertilizer

Urea fertilizer is a synthesis of CO2 and ammonia ; It can be used as plant greenhouse gas fertilizer and aquarium tank aquarium fertilizer, carbon dioxide is the best gas fertilizer, if it is sprayed two times gas CO2 every week. After going though 4 to 5 times spraying , Vegetables can increase 90% and has 70% increase in rice production, 60% increased in soybean yield and even 200% increased in sorghum.

Application of gas nitrogen in Coal chemical industry

In the small water gas production of ammonia plant, the proportion of nitrogen to hydrogen ratio is table after adding the nitrogen, which smooths the operation and reduce  the consumption of synthetic ammonia; In addition, it also use the refined nitrogen (99.99%) to protect the catalyst; With pure liquid nitrogen washing refined Hydrogen and nitrogen mixture, so that the inert gas (methane and hydrogen) is extremely small, the contact of carbon monoxide and oxygen are no more than 20PPm. The consumption of nitrogen wash and nitrogen are about 750m3/t ammonia. Oxygen  is functioned as  the  evaporator of pulverized coal or heavy oil, nitrogen involved in the synthesis and function as  raw materials for gas, and be the safety gas of device (catalyst coal protection will use 99.99% pure nitrogen).

Application of gas nitrogen in chemical factory

In the chemical plant, nitrogen is mainly for the protection of gas, ventilation and washing gas, to ensure safe production. Such as polypropylene production, it need to use pure nitrogen (99.99%) functioning as the protection of gas, replacement gas. High purity nitrogen is a vital source of chemical fiber production. Such as Liaoyang Petrochemical Plant has three sets of 3000 m 3 / hour high purity nitrogen device;Synthetic leather factory also use high purity nitrogen to do protection, such as Yantai synthetic leather factory has a 1000m3/hour high purity nitrogen device.
Forest chemical plants also use nitrogen, as a sensitive adhesive coating, rosin, resin and other production process of protective gas. It can be said that the chemical plant has a big demand for nitrogen, nitrogen is a chemical plant “security gas”. opening up chemical nitrogen is promising. Nitrogen is also an important raw material for synthetic fiber (acrylic, nylon) and synthetic rubber .
