PROCESS DESCRIPTION :
Air Compressor: Air is compressed at a low pressure of 5-7 bar (0.5-0.7mpa). It is done by using the latest compressors (Screw/Centrifugal Type).
Pre Cooling System: The second stage of the process involves the use of a refrigerant for pre-cooling the processed air to a temperature around 12 deg C before it enters the purifier.
Purification of Air By Purifier: The air enters a purifier, which is made up of twin Molecular Sieve driers that function alternatively. The Molecular Sieve separates the carbon dioxide & moisture from the process air before the air reaches the air separation Unit.
Cryogenic Cooling of Air By Expander: The air must be cooled to sub-zero temperatures for liquefaction. The cryogenic refrigeration and cooling are provided by a highly efficient turbo expander, which cools the air to temperatures below -165 to-170 deg C.
Separation of Liquid Air into Oxygen and Nitrogen by Air Separation Column: The air that enters the low-pressure plate-fin type heat exchanger is moisture-free, oil-free, and carbon dioxide-free. It is cooled inside the heat exchanger below sub-zero temperatures by an air expansion process in the expander. It is expected that we achieve a difference delta as low as 2 degrees Celsius at the warm end of exchangers. Air gets liquefied when it reaches the air separation column and is separated into oxygen and nitrogen by the process of rectification.
Liquid Oxygen is Stored in a Liquid Storage Tank: Liquid oxygen is filled in a liquid storage tank that is connected to the liquefier forming an automatic system. A hosepipe is used for taking out liquid oxygen from the tank.
BASIC PRINCIPLE
Our oxygen Plant taps oxygen and nitrogen from the atmosphere air. The feed air is entered into the molecular sieve purification system to separate the moisture and CO2 from the process air. Subsequently, it is liquefied by cryogenic cooling using the latest plate and fin, high-efficiency heat exchangers and expanders. The liquid air gets separated into oxygen and inert gases in the air separation column. Liquid oxygen is stored in a liquid storage tank.
SPECIAL FEATURES OF LIQUID OXYGEN Plant
Plants use an "Oil-free" rotary screw /centrifugal oil compressor working between 0.6 to 1.0 mph.
Use Aluminum Brazed exchangers and packed columns for high efficiency.
Turbo expanders (Oil or Air Bearing) for trouble-free operation.
Plants above "500" are supplied with automatic PLC control.
We provide qualified engineers for supervision, installation, and start-up of all our plants as well as training of manpower at customers' sites.
Very low power consumption with proven performance and zero maintenance required for the machines.
100% reliability for oxygen gas quality for industrial & hospital use.
Liquid purity is high for medical and industrial applications.

1.What is cold box in air separation unit?
An important component in gas separation plants are the so-called "cold boxes". Cold boxes are (pressure) vessels that hold a gas or liquid at a very low temperature. 2.What is ASU in oxygen plant?
A cryogenic air separation unit (ASU) is a plant that utilizes the distinct properties between the primary components of air to produce highly purified oxygen, nitrogen, and sometimes other gases, such as argon.
3.Are oxygen-nitrogen generators safe ?
Yes, As the generator does not add or take anything away from the atmospheric air, you could have one running in a closed room with no change to the overall content of the atmosphere. They also negate the need to store and move potentially dangerous high pressure cylinders on site.
4.Will getting a quotation mean a lot of meeting with engineer ,or searching for lots of facts?
No, in order for us to size & price a system for you, we need 4 things: The required flow of nitrogen/oxygen The required purity of nitrogen/oxygen The input pressure of your compressed air supply The pressure of the nitrogen/oxygen used in your application
