O2 VPSA Generator

Introduction 1. General Description of ASPE O2 Generato This process is completed over and over again until the demand for oxygen is met. As for ASPE’s designed and manufactured oxygen generators, these has constructed technical trust on gas-engineering from domestic and overseas companies based on the best duration and reliance, and excellent and economical efficiency considering on-site condition from its engineering step.   The ASPE generator consists of two tanks filled with a sieve. As high pressure air is introduced into the first tank, it passes through the sieve and N2 is adsorbed. The remaining O2 and Argon are piped to a buffer or storage tank. Just before the first tank becomes completely saturated with N2, feed air is redirected to the second tank which then repeats the above process.  The first tank is then vented to atmosphere which allows the N2 to desorb or release from the sieve. To complete the regeneration of the first tank, a small amount of O2 is used to purge it. 2. About O2 VPSA Generator  The VPSA process uses ZMS (Zeolite Molecular Sieve), which attracts (absorbs) nitrogen from air at low pressure and release (desorbs) it at the vacuum pressure. ASPE system completely  designed as ZMS to be a semipermanentely used without replacement. Application Hospital, Fish Farm, Complete combustion, Ozone, Fermentation, Sewage Treatment plant, cutting/brazing 1. Blower  Blower is he equipment used to produce supplied air. supplied ai is used for separating oxygen from air. 2. Afer-cooler  The purpose of after cooler is of reduce temperature of supplied air down to ambient temperature. 3. VPSA Generator  In order to separate the oxygen frome the blowing air, ZMS (Zeolite Molecular Sieve) is used as adsorbent. VPSA consists of 2 adsorbers. While adsorber "A" is under the process of  Pressurization, production, Purge, Equilibrium of pressure and Desorption, adsorber "B" is regenerated to produce oxygen. 4. Vacuum pump  The purpose of vacuum pump is for removing the adsorbed gases such as nitrogen from the adsorbent. 5. Oxygen buffer Tank  It plays as a buffer in sending the produced oxygen of low pressure into the oxygen compressor stably. 6. oxygen compressor  It is used for compressing oxygen to the extent of what a user need. 7. After-cooler  The purpose of the After cooler is to reduce the temperature of compressed oxygen heated in the process of pressurization. 8. Oxygen storage tank  It is a buffer (storage) tank used to supply the compressed oxygen with certain pressure, purity and flow. 9. LCP  LCP has control of the whole system into operating automatically or manually. It also indicates purity, pressure and flow of the produced. 10. Oxygen supply  The purity of the produced oxygen is 90-95%, Flow and pressure depend on customer's needs.
