The quality of the oxygen gas can be relied upon for hospital and industrial uses.

PROCESS DESCRIPTION :

Air Compressor : Air is compressed at a low pressure of 5-7 bar (0.5-0.7mpa), making use of the latest compressors (Screw/Centrifugal Type).

Pre Cooling System : The second process stage requires use of a refrigerant for pre-cooling of processed air to temperature around 12 degrees Celsius before it enters the purifier.

Purification of Air By Purifier : The air is passed into a purifier made up of twin molecular Sieve driers that function alternatively. The process air is processed to separate the carbon dioxide and moisture by the molecular sieve, before the air reaches at air separation unit.

Cryogenic Cooling of Air By Expander : The air is cooled to sub zero temperatures for liquefaction. Turbo expander allows for the cryogenic refrigeration and cooling, that cools the air to temperature below -165 to-170 deg C.

Separation of Liquid Air into Nitrogen & Oxygen by Air Separation Column : The oil free, carbon dioxide free and moisture free air enters the low pressure plate fin type heat exchanger. The air is cooled inside the heat exchanger below sub zero temperatures by air expansion process in the expander. It is expected to achieve a difference delta as minimum as 2 degree Celsius at the warm end of exchangers. As the air reaches at the air separation column, it gets liquified and separated into nitrogen and oxygen by rectification process.

Liquid Oxygen is Filled in a Liquid Storage Tank : Liquid oxygen is filled in a liquid storage tank, connected to the liquefier creating an automatic system. Liquid oxygen is taken out from the tank using a hose pipe.

Medium Capacity Liquid Oxygen Plant

A TYPE Range - 80 LITRES/hour-170 LITRES/hour (with liquid production LOX and LIN)

Using this Liquid oxygen (LOX) plant, one can generate100% liquid oxygen to be stored into liquid storage tanks or 50% gas & 50% liquid. This plant makes use of leak-proof SS column and skid mounted version for highly pure medical and industrial oxygen for oxygen/nitrogen production for filling tanks.

BASIC PRINCIPLE

LOX Plant makes use of atmospheric air, which is passed into the molecular sieve purification system for removing the moisture and carbon dioxide from the process air. The next process is liquefaction by cryogenic cooling making use of the latest plate and fin, high efficiency expanders and heat exchangers. In the air separation column, the liquid air gets separated into nitrogen, inert gases and nitrogen. Liquid storage tank stores the liquid oxygen.

PROCESS DESCRIPTION :

Air Compressor : At a low pressure of 5-7 bar (0.5-0.7mpa), air is compressed. Latest compressors (Screw/Centrifugal Type) are used for this purpose.

Pre Cooling System : In the second stage of process, refrigerant is used for pre-cooling the processed air to approx. 12 degrees Celsius temperature, before it enters the purifier.

Purification of Air By Purifier : Air passes to the purifier composed of twin molecular Sieve driers that function alternatively. Moisture and carbon dioxide are separated from the process air by the molecular sieve, before the air reaches at air separation Unit.

Cryogenic Cooling of Air By Expander : Liquefaction process demands the air cooled to sub zero temperatures. Turbo expander provides the cryogenic refrigeration and cooling, which also cools the air to temperature below -165 to-170 degrees Celsius.

Separation of Liquid Air into Oxygen and Nitrogen by Air Separation Column : The air free of moisture, carbon dioxide and oil enters the low pressure plate fin type heat exchanger. In the expander, the air is cooled inside the heat exchanger below sub zero temperatures by air expansion process. It is expected to achieve a difference delta as low as 2 degree Celsius at the warm end of exchangers. At the air separation column, air is liquefied and separated into nitrogen and oxygen by rectification process.

Liquid Oxygen is Stored in a Liquid Storage Tank : Liquid oxygen is filled in a liquid storage tank, connected to the liquefier creating an automatic system. Liquid oxygen is taken out of the tank by a hose pipe.

Large Capacity Liquid Oxygen Plant

A TYPE Range 200 LITRES/hour-1000 LITRES/hour (with liquid production LOX and LIN)

100% liquid oxygen (LOX) and liquid nitrogen (LIN) are generated by the large capacity liquid oxygen plant, which are filled into cryogenic storage tanks. LOX plant can also generate 50% oxygen or 50% gas.

Our LOX plants or LIN plants make use of leak-proof SS column and skid mounted version for highly pure industrial and medical use oxygen.

BASIC PRINCIPLE

Our large capacity LOX plant uses atmospheric air as feed air in the sieve purification system for eliminating moisture and carbon dioxide from the process air. The feed air is then liquified by cryogenic cooling making use of the plate and fin, heat exchangers and expanders. In the air separation column, the liquid air is separated into oxygen and inert gases. Liquid storage tank contains the liquid oxygen.

Expander through air expansion process cools down the air inside the heat exchanger below sub zero temperatures. It is expected that a difference delta as low as 2 degree Celsius is achieved at the warm end of exchangers.
