PSA Air Separation Unit for 99.9% purity Nitrogen Gas

  PSA Air Separation Unit for 99.9% purity Nitrogen Gas  
  FAQ   What is PSA?   Pressure Swing Adsorption is a common air separation method tosepate nitrogen or oxygen from air .The separation process operate around ambient temperature.PSA air separation plant for nitrogen gas takes the carbon molecular sieve as the adsorbent,which  adsorbs oxygen and water vapor molecules under high pressure - while allowing Nitrogen to pass through,so that the nitrogen is separated from the air.   It is a favourable choice to make your own nitrogen!!    PSA air separation plant for nitrogen gas is on -site nitrogen generation, a favorable choice for many manufacturers as it is an easy and reliable way for them to save money and give free control over the nitrogen gas use,also reliable and cost effective way to get the nitrogen for industrial usage.    Main Technical Indicators:

       What is the technological process?  Ambient air, having being compressed and purified to remove oil, water and dust, enters the adsoption swing adsorping device with two adsorption towers filled with carcon molecular sieve(CMS). The compressed air flow to the adsorption tower from the bottom to up. In the process, oxygen molecular is adsorbed, while nitrogen flows out of the upper side of adsorption tower and then enters then buffer tank for impure nitrogen. After a period of time, the CMS in the adsorption tower is saturated by the oxygen adsorbed. At this time, regeneration is needed. It is realized by stopping adsorbing step and reduce pressure in the adsorption tower. Adsorption and regeneration are conducted alternatively in the two adsorption towers to ensure the consecutive output of nitrogen gas.   What are the main components of the whole system?  The whole nitrogen generation system mainly consists of the air compressor, the compressed air receiver, filters, refrigeration dryer, the PSA nitrogen generator, and the nitrogne receiving tank.   What brande do the users usually  require?   For the air compressor, famous brand such as the Atlas Copco, the Ingersoll Rand can be available from our company to match the PSA nitrogen generators. For filters, the elements with brand of Hankison, Domnick are available. For refrigeration dryer, we have J.mec, the first brand within China, also Hanzhou Union Filter the professional manufacturer of dryer and filters.   How to ensure better service life of the whole nitrogen system?   Enhancement:To ensure the better quality and longer service life, the main parts such as CMS and PLC, we use world famous brand Japan Takeda and MITSUBISHI, for valves, we use Germany Burkert solenoid valves and pneumatic valves.   What is the consumables of the nitrogen system? The main consumables of the nitrogen system are the carbon molecular sieves(CMS) and the filter element. For the CMS, the service life is usually 5 to 8 year for normal use, and for the filter element, it needs to be replaced for every 6 to 8 months.         FAQ: What is the service life of Carbon molecular sieves(CMS)   Usually, for normally use, the life span of the CMS is about 5 to 8 years.   What is the cycle time to replace the filter element? Usually, the filter element needs to be replaced for every 6 to 8 months.         Packaging & Shipping  Seaworthy packing is offered and delivery will be made in 60 days after order confirmed based on the price term of FOB Shanghai.   What industry are you in and what capacity you need for the nitrogen, come to us, let us help to make you own nitrogen.
