Contact SupplierWe are manufacturers and suppliers of Liquid Oxygen Nitrogen Plants in India. Our liquid oxygen plant are being manufactured as per the latest technology & design of the Company ING. L. & A., BOSCHI, ITALY. This technology has been proven all over the world for its working efficiency & trouble free operation.
Small Capacity Liquid Oxygen PlantA TYPE Range – 20 LITRES/hr to 60 LITRES/hr (with liquid production LOX and LIN)
(FOR 100% LIQUID PRODUCTION FOR FILLING LIQUID TANKS or 50% gas & 50% liquid) FOR PRODUCTION OF LIQUID OXYGEN /NITROGEN FOR FILLING IN TANKS With leakproof stainless steel column and skid mounted version for high purity medical and industrial oxygen.
BASIC PRINCIPLE
Our oxygen plants 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 PLANTS
PROCESS DESCRIPTION :
Air Compressor :Â 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 :Â The second stage of the process involves use of a refrigerant for pre-cooling the processed air to temperature around 12 deg C before it enters the purifier.
Purification of Air By Purifier :Â 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 at air separation Unit.
Cryogenic Cooling of Air By Expander :Â The air must be cooled to sub zero temperatures for liquefaction. The cryogenic refrigeration and cooling is provided by a highly efficient turbo expander, which cools the air to temperature below -165 to-170 deg C.
Separation of Liquid Air into Oxygen and Nitrogen by Air Separation Column :Â 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 air expansion process in the expander. It is expected that we achieve a difference delta as low as 2 degree Celsius at the warm end of exchangers. Air gets liquefied when it reaches at 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 :Â Liquid oxygen is filled in a liquid storage tank that is connected to the liquefier forming an automatic system. A hose pipe is used for taking out liquid oxygen from the tank.
