| THE PSA
CONCEPT How Oxygen is Obtained from ambient air. Pressure Swing Adsorption
(PSA) technique is utilised to obtain Oxygen from atmospheric air. Compressed
air at about 4-6 bar, depending on the size of the unit is processed
via a compressor or from a compressed air network alternatively in two
towers equipped with special grade of Molecular Sieves (Adsorbers A
and B). Through the pressure change controlled electronically by valve
block D, Nitrogen, moisture and Carbondioxide are adsorbed and desorbed. In Adsorber A the incoming air is freed of N2, H2O & CO2, which are adsorbed by Molecular Sieves of tower A. The outgoing oxygen is stored in buffer tank C. After a preset period, the process of adsorption automatically switches to Adsorber B. Whilst B is being filled, A is emptied bya pressure drop and venting to atmosphere. Venting with Oxygen from the other tower ensures that the Nitrogen and other impurities are completely removed from the Molecular Sieves. |
| COMPACT UNITS FOR INDEPENDENT PRODUCTION OF OXYGEN |
|
INDCON PROJECTS manufacture PSA based Oxygen Generators of production capacity upto 25 NM3/hr. The product gas purity can be upto 95% Oxygen. These PSA Oxygen Generators are ideal for economic utilization in several areas. Because of their compact construction, these equipment require little space and can be erected practically anywhere without any special constructional measures being required. Apart from compressed air supply, a single phase power source is required for the operation of Sequence Programmer. |
