Nitrogen Generator

Features of N2 PSA Generator Compact system with simple structure through optimum design Fully automated unattended operation by the electronic control Since the nitrogen can be produced on site using the compressed air, it is not affected by the delivery delay or nitrogen price change of high priced liquid nitrogen. The system can be customized according to the user requirements about nitrogen purity, production rate and gas delivery pressure, etc. (95~99.9999%, 1-600Nm3/Hr) CMS, the absorbent used in gas separation, can be semi-permanently used. There is no need to have it managed by the dedicated safety personnel or to keep the gas container since it is operated at low pressure and not subject to the High Pressure Management Act. Reasons the On-Site Nitrogen Generators Must Be Selected If you use two or more nitrogen cylinders per week, the cost of a nitrogen generator can be recouped within 1 year and 6 months. Since it uses the compressed air, the high purity nitrogen gas can be produced at low cost. The nitrogen generator can be semi-permanently used by just regularly maintaining the air preparation unit. There is no need to have it managed by the dedicated safety personnel since it is operated at low pressure and not subject to the High Pressure Management Act. There is no need to worry about possible delay of nitrogen gas delivery and no need to keep the nitrogen gas cylinder Pressure Swing Adsorption(PSA) TechnologyA PSA system can separate the gas compounds by using the difference of adsorption force of the various chemical compounds (adsorbent) to each gas. In the gas separation process, the compressed air passes through the molecular sieve layer composed of crystals with small pores and the gases are adsorbed to the sieve by the adsorbent while the gas to be separated is freely passed through the layer. In the PSA nitrogen generator, the moisture controlled, compressed air is charged to two or more adsorption towers packed with the adsorbent called CMS (Carbon Molecular Sieve). Then compression ?adsorption ? decompression ? purge steps are repeated to continuously produce the high purity nitrogen CMS is made of the bark of palm tree and has many pores of 4A. Since the outer diameter of the oxygen molecule is 3.8A and that of nitrogen molecule is around 4.2A, the system uses the principle of oxygen quickly being adsorbed first due to the difference in diameter. Therefore it is important to select the product that maintains a certain compression temperature and has the uniform sized pores in order to produce high purity nitrogen. Five Reasons the On-Size Nitrogen Generator Must Be Selected If you use two or more nitrogen cylinders per week, the cost of a nitrogen generator can be recouped within 1 year and 6 months.
