Oxygen VPSA System

DESCRIPTION

Generate High Purity Oxygen directly in gaseous form. Power efficient systems with Flow achievable from 500-5000 Nm3/hr.

PROCESS DESCRIPTION

Air from a Blower is first cooled in an Aftercooler to reduce its moisture content and condensed moisture is separated in Moisture Separator. The cooled air passes through a Tower containing an adsorbent which has the property to separate oxygen from the air resulting in a gas contains 93% oxygen (balance being argon & nitrogen) coming out as product gas.

To ensure continuous flow of product gas, the other Tower is simultaneously regenerated by extracting the gases adsorbed in the previous cycle by a Vacuum Pump. Automatic operation is achieved by opening & closing the valves in a preset sequence by using a PLC.

The oxygen product flow is compressed to the required discharge pressure, if required and fed to end use process.

The waste gas is 80-85% Nitrogen and 11-15% Oxygen which is vented to atmosphere via discharge silencer.
