LIQUID OXYGEN PLANTS
We “BDM Cryofusion & Mandressi ITALIA” are a well-established name in the engineering sector and are engaged in manufacturing a wide range of liquid oxygen plants, that are in compliance with North American and European Pharmacopoeia standards. These precision engineered cryogenic liquid oxygen plants are available in varying sizes from 50 m³/hr (70 liter/hour) to 500 cum/hr (700 liters/hour) capacity. Designed by experienced engineers, these are highly safe & efficient to operate and perfectly meet the application requirements of our industrial clients.
The output of liquid oxygen from these plants can be stored in a liquid oxygen tank. Liquid nitrogen can also be available as a by-product simultaneously with up to 99.99% (PPM GRADE) purity. These plants are extremely versatile and all the possible product variants can either take 100% Liquid oxygen output or 50% Liquid oxygen output directly into cylinders or 50% Liquid oxygen and 50% Liquid nitrogen. |
LIQUID OXYGEN PLANTS
 | PROCESS DESCRIPTION:
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.
