Oxygen Gas Plants

BDM Cryofusion & Mandressi Italia in technical collaboration with an internationally renowned Italian company "Felice Mandressi Italia" manufactures and fabricates high quality oxygen plants of all sizes ranging from 50m³/hour to 50,000m³/hour. Our engineers fabricate the oxygen generating machinery using high quality raw materials. With the well-equipped R & D unit, latest manufacturing processes and highly skilled workforce, we fabricate plants that are globally competitive both in terms of quality and prices. Each machine is put through a stringent quality test before it is shipped.

Our oxygen gas plants are manufactured and fabricated at our production units in India and are exported all over the globe. Being manufactured in compliance with international standards, our plants are superbly designed and can compete with the best in the field. We ensure that our machinery delivers seamless performance, requires low power consumption and maintenance. To know more about our products and services, consult our customer care executives. They are available around the clock to help customers and answer their queries.

Oxygen Gas Plant Skid

Basic principle

Our oxygen gas plants tap atmospheric air. Subsequently, the feed air enters the molecular sieve purification system where the process air gets separated from the carbon dioxide and moisture. Then, it is liquefied by cryogenic cooling by using the latest plate and fin, high efficiency heat exchangers and expanders. The liquefied air gets separated into oxygen, nitrogen and various other inert gases in the air separation column.

Oxygen Gas Plant
Scope and Supply :
Air compressor
Air is compressed at a low pressure of 5-7 bar using the latest compressor (screw/centrifugal type).
Pre Cooling System
In the second stage, a refrigerant is used for pre-cooling the process air to temperature around 12 degrees Celsius before it enters the purifier.
Purification of Air by Purifier
Air is made to go inside a purifier made of twin molecular sieve driers, working alternatively. The sieve separates the moisture and carbon dioxide from the process air before it enters the air separation unit.
Cryogenic Cooling of Air by Expander
Air is cooled to sub zero temperatures for liquefaction and cryogenic refrigeration. Cooling is provided by highly efficient expander. Air is cooled to temperatures below -165 to -170 degrees Celsius.
Separation If Liquid Air into Oxygen and Nitrogen by Air Separation Column
Air is separated from moisture and carbon dioxide before it enters the low pressure plate fin type heat exchanger where it is cooled below sub zero temperatures by air expansion process in the expander. However, a temperature difference delta as low as 2 degree Celsius can be achieved at the warm end of these exchangers. On reaching the air separation column, air gets liquefied and is separated into oxygen and nitrogen by the process of rectification.
Compression of Oxygen filling in the Cylinder
The end product in the form of compressed oxygen is directed to high pressure cylinders at 150 bar or higher. It is required for pipeline supply, captive consumption or for liquid plants to fill in cryogenic liquid tanks.
