Liquid Oxygen Nitrogen Plant

Low energy Liquid Oxygen Nitrogen Plant by DCPL

We manufacture cost-effective, safe and reliable liquid oxygen and nitrogen generating systems for high quality industrial and medical use.

Currently our plants and machineries are being supplied and commissioned in India and many countries worldwide, we are serving the markets for requirements of bottling cylinders, industrial gas cutting of steel, brazing of metals, production of steel glass and ampule industry, petrochemical industry, fabrication, medical use in hospitals, oil & gas industry, animal husbandry.

Our process is based on the latest design and technology of Cryogenic liquefication of air where the basic principle of deep refrigeration / cooling is used to liquefy the atmospheric air specially suitable to produce liquid oxygen / nitrogen and filling cryogenic storage tanks.

The plants are of proven technology and are safe to operate for production of medical and industrial oxygen because the pure oxygen can be filled directly into cylinders without coming into contact with the air or moisture.

Liquid Oxygen Nitrogen Production Process

1. Compression Of Atmospheric Air By Air Compressor

Air is compressed by Ingersol Rand or equivalent air compressor and then cooled theough an after cooler

2. Pre Cooling System

The second stage of the process uses a lrefrigeration unit for pre-cooling the processed air to temperature around 12 deg C before it enters the purifier.

3. Purification Of Air By Purifier

The air enters a purifier consisting 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.

4. Cooling Of Air By Expander

The air has to be cooled to sub zero temperatures for liquefication & the cryogenic refrigeration & the cooling is provided by the expansion engine, which cools the air to temperature almost below -165 to-170 deg C

5. Separation Of Liquid Air Into Oxygen And Nitrogen By Air Separation Column

Oil free, moisture free and Carbon Dioxide free air enters into coil type HEAT EXCHANGER where the air is cooled below sub zero temperatures by air expansion process in the expander. Air gets liquefied when it enters the air separation column & gets separated into oxygen & nitrogen by the process of rectification. Liquid Oxygen is available at the outlet of the ASU at a purity of 99.7%. Liquid Nitrogen is also available at the outlet as a second product at purity of 99.9% upto 3ppm simultaneously without loss of oxygen product.

6. Storage Of Liquid Oxygen And Liquid Nitrogen

The final product in the liquid Oxygen/Nitrogen goes to the vaccuum insulated cryogenic storage tank at pressure of 8 bar ot 16 bar as desired by the user.
