Membrane air separation of nitrogen called hollow fiber membrane separation, It is made of air, which can separate oxygen and nitrogen under certain pressure by using different gases such as oxygen and nitrogen to have different infiltration rates in the membrane. Compared with other nitrogen plant it is more simple structure, smaller volume, no switch valve, less maintenance, produce gas quickly (≤3 minutess), convenient of capacity, it is especially suitable for medium and small of the nitrogen purity to 99.5% or less nitrogen users, have an optimal function price. When the purity of nitrogen is over 98%, the price is more than 15% higher than that of PSA nitrogen generator of the same specification.  

Deep freezing technology is the most widely used air separation technology at present, and it is also the focus of competition among countries in air separation technology. Cryogenic technology uses the principle of different boiling points of oxygen and nitrogen gases under the same pressure to separate gases Compared with the separation device of other processes, the air separation device developed by cryogenic technology can easily meet the requirements of high yield and high purity, which can meet the requirements of modern large-scale industrial production. Therefore, the most discussed and widely used in the air separation industry is the air separation device using cryogenic technology.

What classifications of the piston type compressor? The piston compressor has various kinds of types, and also has different kinds of classification. It is classified into vertical, horizontal type, angle type, symmetrical balance and contrast-position type according to the figuration of cylinder in the piston compressor. It can be classified into single stage type, double stage and multistage according to the the compressed series of the piston compressor. As for the set mode of the piston compressor, it can be classified into mobile type and stationary type. It can be classified into unloading type and pressure switch type according to the control type of the piston compressor. How the compressor works? The theory of the piston compressor works: AS the

With the rapid development of China’s economy, the importance and role of industrial gases in the economy have become increasingly prominent. As an important basic raw material for modern industry, gas products have a wide range of applications. Industrial gases mainly include oxygen, nitrogen, argon, helium, neon, krypton, xenon, hydrogen, carbon dioxide, acetylene, natural gas, etc., involving all aspects of industry. The industrial gases mentioned in this paper mainly refer to the ability to separate and obtain oxygen, nitrogen, and argon through air filtration equipment. Rare gases such as helium and neon can also be obtained by further purification. Preparation of oxygen, nitrogen, and argon is mainly achieved through air separation equipment. Large-scale air separation equipment is mainly used in

Would you like to know how to manufacture the industrial rare gas? Although the industrial gas is usually the nitrogen, but it not as rare gas. Nitrogen is air separated, rectified from the air cryogenic liquefied, then the nitrogen and oxygen can be got etc. Helium is mainly from the natural gas, because its content in the air is too little, some mineral resources of the natural gas contain much Helium. It can be air separated by liquefaction, Helium is one kind of rare resources, it is really little in the earth, it is basically non-renewable resources, the price is increasing recent years. Certainly, Helium is also got form the air separation, because Helium and neon are really difficult to
