Psa Nitrogen Generator and Psa Oxygen Generator

PSA air separation plants includes PSA nitrogen generator and PSA oxygen generator

The Nitrogen-Generator produces pure nitrogen by separation of compressed air, using PSA technology (Pressure-Swing-Adsorption). The applications for Nitrogen-Generators are manifold like reflow soldering, metallurgic processes, brazing, welding, heat treatment, Laser cutting and many others. Besides these "classical" applications in metal related industries, nitrogen also plays an important role in other economic sectors, as well as it is widely-used as inert gas for research purposes. On our Applications Page, we have summarized possible areas of applications for nitrogen generators.

The Oxygen-Generator produces pure oxygen by separation of compressed air, using PSA technology (Pressure-Swing-Adsorption). In any chemical, biological, and bio-technological processes oxygen is needed. It is also used in many industrial applications like glass melting furnaces or metallurgic processes. Hospitals and other medical facilities require oxygen as well. Water treatment plants use oxygen, and also the food industry uses it. 
PSA nitrogen generator working Principle
The raw material compressed air through the air pretreatment device to remove dust, oil and other solid impurities and water, through the air diffusion distributor into the dry molecular sieve and oxygen separation of molecular sieve adsorption tower, the depth of drying after the oxygen and nitrogen separation from the top of the adsorption tower. The gas is nitrogen with high purity. This process is completed by the two adsorption towers crossed, one work, one regeneration, and continuous preparation of nitrogen. This part of the nitrogen gas after high efficiency nitrogen dust collector into the nitrogen receive tank. Here, regeneration means, the adsorption tower gas will be discharged to the atmosphere and the pressure quickly reduced to atmospheric pressure, while the molecular sieve adsorption of oxygen, carbon dioxide and other release from the molecular sieve process.

Equipment composition
The PSA nitrogen generator equipment consists of gas source purification system, gas tank, nitrogen generator and a nitrogen process tank. 
1. Air purification: The conventional configuration is composed of a refrigerated dryer and a four-stage filter. The main purpose is to reduce the temperature of compressed air, remove impurities such as oil and dust, and dry moisture. For users with a higher nitrogen dew point (greater than -40°C), the dryer can be combined with a dryer (dew point -60°C to -70°C). (General configuration)
2. Air process tanks: Pressure gauges, drain valves and safety valves are mainly used to reduce the air flow pulse and ensure the smooth operation of the air flow. 
3, nitrogen master: From the adsorption tower, control cabinets, cylinders, valves and pipelines. Among them, our molecular sieves are selected from molecular sieve molecular sieves and 13X molecular sieve desiccants. 
Pneumatic valves use the BURKERT 2000 Series piston angle seat valves. (This valve can operate more than 2 million times without failure)
4, nitrogen process tank: To balance the nitrogen flow output from the nitrogen generator to ensure continuous and stable supply of nitrogen

PSA nitrogen generator operating procedures
First, boot steps: 
1. Check if the on-site power supply meets the requirements of the dryer and the nitrogen generator (watch the equipment nameplate)
2. Turn on the dryer and press the "start" button of the dryer. After the dryer starts for 5 minutes, open the compressed air intake valve (ie, the inlet valve of the dryer). 
3, open the air compressor. Press the air compressor start button and the air compressor starts to work. 
4. When the air tank pressure rises to 0.8MPa, adjust the gas source two-pieces to control the air source pressure in the range of 0.4-0.6MPa. 
5. Start the control cabinet start button and start the nitrogen generator. 
6. After the gas generator valve (valve 9#) is opened, open the nitrogen gas tank inle
