Liquid Nitrogen 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.
