Oxygen gas Generator

Oxygen gas Generator system works on the principle of Pressure Swing Adsorption, widely termed as PSA. This conventional gas separation technology is being used to separate Oxygen from Compressed air. The major components are a pair of Adsorbent vessels, Surge tank, Switching valves, Intelligent PLC, Oxygen analyzer ,oxygen booster, manifold and instruments. The adsorbent vessels filled with Zeolite preferentially adsorbs Nitrogen and CO2 whereas Oxygen is not adsorbed by Zeolite due to its larger molecular size and passes through the adsorber to the surge tank. Based on the prefixed time interval the online adsorber switches to regeneration mode and Adsorbed gas from Zeolite are purged out to the atmosphere. During this operation Oxygen analyzer monitors the oxygen concentration and allows Oxygen Gas to storage tank. If oxygen concentration is less than the pre-set value PLC switches the vent valve and purging out the gas till it reaches the required purity level
