Renewable Design for Medical Oxygen Gas Generator - PSA oxygen concentrator/Psa Nitrogen Plant for sale Psa Nitrogen Generator – OuRui

Oxygen is an indispensable gas for supporting life in the earth, special in the hospital, medical oxygen plays a very important role to saving the patients.
ETR PSA Medical Oxygen Plant can produce medical level oxygen from the air directly. ETR Medical Oxygen Plant is consisted of Atlas Copco air compressor, SMC dryer and filters, PSA oxygen plant, buffer tanks, cylinder manifold system. The HMI control cabinet and APP monitoring system support for the online and remote monitor.

Compressed air is purified through the air dryer and filters to a certain level for main generator to work with. Air buffer is incorporated for smooth supply of compressed air thus to reduce fluctuation of compressed air source. The generator produces oxygen with PSA (pressure swing adsorption) technology, which is a time proven oxygen generation method. Oxygen of desired purity at 93%±3% is delivered to oxygen buffer tank for smooth supply of product gas. Oxygen in buffer tank is maintained at 4bar pressure. With an oxygen booster, the medical oxygen can be fill in cylinders with 150bar pressure.

Process Flow Brief Description

Technical Features

PSA oxygen generator plant is fabricated using advanced Pressure Swing Adsorption technology. As is well-known, oxygen constitutes around 20-21% of atmospheric air. PSA oxygen generator used Zeolite molecular sieves to separate the oxygen from the air. Oxygen with high purity is delivered whereas the nitrogen absorbed by the molecular sieves is directed back into the air through the exhaust pipe.

Pressure swing adsorption (PSA) process is made up two vessels filled with molecular sieves and activated alumina. Compressed air is passed through one vessel at 30 degrees C and oxygen is generated as a product gas. Nitrogen is discharged as an exhaust gas back into atmosphere. When the molecular sieve bed is saturated, the process is switched to the other bed by automatic valves for oxygen generation. It is done while allowing the saturated bed to undergo regeneration by depressurization and purging to atmospheric pressure. Two vessels keep working alternately in oxygen production and regeneration allowing oxygen is available to the process.

Applications of PSA Plants

Our PSA oxygen generator plants are used across numerous industries including:

• Paper and Pulp industries for Oxy bleaching and delignification
• Glass industries for furnace enrichment
