Zeolitic molecular sieves are used as adsorption agents when producing oxygen from the air by adsorptive means. They adsorb nitrogen, water vapor, and carbon dioxide to a much higher degree than oxygen. This means that a product flow comprising essentially only oxygen and argon can be removed from the process air being passed through the adsorption bed. The compressed air enters the adsorbers. The nitrogen is adsorbed while the oxygen product leaves the vessels. After a certain time the adsorption is interrupted and evacuation by a vacuum pump desorbs the enriched nitrogen. The oxygen product flow is compressed to the required discharge pressure, if required.
VPSA/PSA plant working Principle
In this process consists of 2 or 4 beds filled with Molecular Sieves. These cycle alternately in Production and in Regeneration. Feed air pressure is supplied with air blowers at 0.25 to 0.5 Bar, which gives Oxygen production at 0.20 to 0.45 Bar. Regeneration of Molecular sieves is achived by a highly efficient water cooled Vacuum pump at 0.6 Bar pressure. in a result Product Oxygen gas purity is achived around 90 to 95% The waste gas is 80-85% Nitrogen and 11-15% Oxygen which is vented to atmosphere via discharge silencer.Speciallized X type molecular sieves are used as adsorption agents when producing oxygen from the air by adsorptive means.They adsorb nitrogen, water vapor, and carbon dioxide to a much higher degree than oxygen. This means that a product flow comprising essentially only oxygen and argon can be removed from the process air being passed through the adsorption bed. The compressed air enters the adsorbers. The nitrogen is adsorbed while the oxygen product leaves the vessels. After a certain time the adsorption is interrupted and evacuation by a vacuum pump desorbs the enriched nitrogen. The oxygen product flow is compressed to the required discharge pressure, if required.
