Universal Boschi cryogenic liquid nitrogen systems/oxygen plant are 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 Pharmacopia 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 upto 99.999% (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.


FLOWSHEET OF CRYOGENIC LIQUID OXYGEN/NITROGEN PLANTS






Production Process

Air is sucked by a multi stage air compressor and air passes through the following process.

COMPRESSION OF AIR
This is done by the multistage highly efficient air compressor.












PURIFICATION OF AIR
This is done by the PROCESS SKID.















COOLING & LIQUIFICATION OF AIR
This is done by a highly efficient expansion engine and also by a refrigeration unit (for 100% liquid output).


AIR SEPARATION (RECTIFICATION)
This is done by the special ‘BOSCHI’ type AIR SEPARATION UNIT consisting of upper & 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.






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. Universal has developed the necessary technology and has been manufacturing these cryogenic equipment like cryogenic vessels since last seven years.
