Oxygen is needed in many industrial applications. Bulk quantities of oxygen are required by these industries, which cannot be fulfilled by buying oxygen cylinders. 100% pure oxygen cannot be produced by a membrane oxygen generator. So, MVS Engineering Pvt. Ltd offers PSA oxygen plants that can produce purer oxygen gas that can be used for all purposes.
Differences between a PSA plant and a membrane oxygen generator
Both the PSA oxygen plant and membrane oxygen plant are skid-mounted or mounted on a platform when installed at the customer’s site. However, there are many differences between these two varieties of oxygen plants.
● Only 30% to 45% pure oxygen is available from a membrane oxygen generator. On the other hand, 93% – 95% pure oxygen is produced by a PSA oxygen plant.
● A membrane oxygen plant has a production capacity of upto 10000 m3/h, under the pressure of 0.1 MPa. On the contrary, the PSA oxygen plant can produce oxygen gas that is equivalent to 10 – 300 cylinders.
● The dew point of oxygen produced from a membrane oxygen generator is low. On the other hand, the dew point of oxygen gas produced by a PSA oxygen generator is –40°C and the temperature maintained during this process is 30°C.
A simple PLC control system is applied in a PSA oxygen plant, which is automatic and minimizes the manpower to handle this device. If the purity of oxygen drops below 90%, production stops immediately with an alarm. A backup system is maintained with pre-filled oxygen cylinders, to continue the oxygen supply not to disrupt the reason for which oxygen is needed.

Iron and steel industries need a continuous supply of oxygen for welding and cutting of metals. Fish farming also needs oxygen for the artificial incubation of eggs of fish, crabs, and shrimps. Chemical industries need oxygen for the oxidation of certain elements and to burn dangerous materials evolving during chemical processes. PSA oxygen generators of MVS Engineering are preferred over membrane oxygen generator in all these industries.
