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.
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.
