Liquid Series Oxygen-Nitrogen Plants

The cryogenic liquid Oxygen/Nitrogen plant available in size from 50 m³/hr (70 liter/hour) to 500 cum/hr (700 liters/hour) capacity. It is safe and efficient to operate and the oxygen confirms to North American and European Pharma copia and standards.

The output of Liquid Oxygen can be stored in a liquid oxygen tank. Liquid Nitrogen can be available as a by product simultaneously up to 99.99% (PPM GRADE) purity.

The plant is extremely versatile and all the possible product variants are possible you can either take 100% Liquid oxygen out put or 50% Liquid oxygen output directly into cylinders or 50% Liquid oxygen and 50% Liquid nitrogen.

Liquid Plant

STEP I: Air is sucked by a multi stage air compressor and passed through the following stages.

STEP II: COMPRESSION OF AIR

This is performed by the multistage highly efficient air compressor.

STEP III: PURIFICATION OF AIR

This is performed by the Process Skid.

STEP IV: COOLING & LIQUIFICATION OF AIR

This is performed by a highly efficient expansion engine and also by a refrigeration unit (for 100% liquid output).

STEP V: AIR SEPARATION (RECTIFICATION)

This is performed by the special AIR SEPARATION UNIT consisting of upper column, lower column and special exchangers. The separation air is by the CRYOGENIC PROCESS. The final product from a liquid Oxygen/Nitrogen goes to the storage tank.

STEP VI: CRYOGENIC STORAGE TANKS

Cryogenic Vessels are designed for storage and transport of liquid gases at sub-zero temperatures. Manufacturing of such cryogenic tanks requires special technical know how and sophisticated fabrication techniques. We have developed the necessary technology and has been manufacturing cryogenic vessels.
