[Features]
Pressure Swing Adsorption (PSA) is a technology that can separate the desired gas compounds by using the difference of adsorption force of the individual crystals of gas from Molecular Sieve. In other words, adsorption may be defined as binding the gas molecules to the Adsorbent that is a solid substance through the suction force of the molecule.
A PSA system can separate the gas compounds by using the difference of adsorption force presented by the various chemical compounds or each individually. In the gas separation process, the compressed air passes through the Molecular Sieve x-layer composed of crystals with micro pores and the gases to be adsorbed becomes adsorbed by the adsorbent while the gas to be separated passed through the x-layer freely. The PSA Nitrogen Generator with the adsorbent called CMS (Carbon Molecular Sieve) phases in the compressed air filled with two or more adsorption towers that are moisture controlled, progresses the following steps that are repeated: compression -4 adsorption -4 decompression ^ purge to
continuously produce the high purity Nitrogen.
Compact system with simple structure through optimum design. Fully automated unattended operation by the electronic control.
Since the nitrogen can be produced on site by 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.
Features of Membrane Type Nitrogen Generator
⦁ Nitrogen is simply produced from dry compressed air.
⦁ No noise is generated as the adsorption/recovery cycle is not needed.
⦁ Light weight and smaller size require less space for installation.
⦁ It can be arranged horizontally or vertically.
⦁ No power is needed for the nitrogen generator module.
[Applications]
Electrical components and connections meet CE standards. All pressure vessels are designed to meet ASME code(Section VIII, Div. 1).
Membrane Type Nitrogen Generator.
Gas separation using the membrane applies the principle of selective gas permeation of the membrane. The substance of the membrane determines the relative solubility and ransmittance of each gas component. For the membrane type nitrogen generator, polyimide or polysulfone is used. The membrane type nitrogen generator from WON Hi Tech uses a hollow fiber gas separation membrane which transmits more oxygen than nitrogen. In other words, when the compressed air is passed through the polyimide hollow fiber membrane, the nitrogen, which passed relatively more slowly, is passed through the high pressure side (inside of the membrane) while the oxygen is passed through the low pressure side (outside of the membrane) and discharged to the atmosphere.
