Nitrogen Plants

In technical collaboration with "Felice Mandressi Italia", we manufacture and supply premium quality low pressure pure nitrogen plants of all sizes ranging from m3/hour to 50,000m3/hour. We also manufacture and fabricate cryogenic tonnage gas plants, oxygen/nitrogen/acetylene plants and air separation plants. Advanced technology and superb designs are employed in the manufacturing of our world-class machinery. Because of using the cutting-edge technology of the famous Italian company, our plants are of high quality and are known to function seamlessly while needing low power consumption and low upkeep expenses. On the other hand, our pure nitrogen plants generate nitrogen with a purity up to 99.99%, which is considered good for both medical as well as industrial applications.

Since our establishment in 1997, we have sold over 300 plants to clients in 40 countries across the globe including Nigeria, Lebanon, Saudi Arabia, Yemen, UAE, South Africa, Qatar, The UK, Canada, Sudan, etc. All our clients are satisfied with the performance our plants as well as after sales service. Being a quality conscious company, we ensure that all machinery is manufactured in compliance with international standards. All components used in our plants are put through stringent testing and manufactured plants are also thoroughly tested before they are shipped. We have been awarded ISO 9001:2009 and CE certifications. It is mandatory for exporters to have CE certification if they want to sell their machinery into the US and the European market.

Basic principle

Air separation plant takes oxygen and nitrogen from the air simultaneously. The pretreated air enters the molecular sieve purification system, which is employed to separate the moisture and carbon dioxide from the processed air. The air is liquefied by cryogenic cooling using the latest plate and fin high efficiency heat exchangers and turbo expanders. The liquid air gets separated into oxygen, nitrogen and inert gas in the air separation column.

Scope and Supply :
Air Compressor
Air is compressed at a very pressure of 5-7 bar (kg/cm2) by trouble free compressor (Screw / Centrifugal Type).
Pre Cooling System
The second stage of the process uses a low pressure refrigerant for pre-cooling the processed air to temperature around 12 deg C before it enters the purifier.
Purification of Air by Purifier
Air enters a purifier made up of twin molecular sieve driers, working alternatively. The molecular sieves remove the carbon dioxide & moisture from the processed air before the air enters Air Separation Unit.
Cryogenic Cooling of Air by Expander
Air has to be cooled to sub zero temperatures for liquefaction & the cryogenic refrigeration. The cooling is provided by highly efficient expander, which cools the air to temperature almost below -165 to-170 degree Celsius.
Separation of Liquid Air into Oxygen and Nitrogen by Air Separation Column
After air is purified of moisture and carbon dioxide, it enters low pressure fin type HEAT EXCHANGER where the air is cooled below sub zero temperatures by air expansion process in the turbo expander. Air gets liquefied when it enters the air separation column & gets separated into oxygen & nitrogen by the process of rectification.
Filling tanks/cylinders
It is the last step where liquid oxygen is filled into tanks and cylinders to be delivered onto the end-users. Nitrogen gas is available at the outlet with purity of 99.99% upto 3ppm (lppm in some models). Liquid nitrogen is also available along with the pure nitrogen gas products.
