LIQUID NITROGEN PLANTS
| Employing the latest Liquid Air Separation Technology, we “BDM Cryofusion & Mandressi ITALIA” manufacture premium quality liquid nitrogen plants. Fabricated from well-tested stainless steel column using flanged connections and argon welded column, these plants provide easy accessibility and servicing. These plants provide efficient heat exchange to attain minimum power consumption and thereby reduce the cost of operation. Our plants offer high purity of nitrogen 99.5% and are compatible with soft drinks, juices, beverages and other industrial applications. |
LIQUID NITROGEN PLANTS
 | 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.
