Basic principle

Our oxygen nitrogen plants take nitrogen from the atmospheric air. The feed air goes into the molecular sieve purification system where the processed air is separated from the moisture and CO2. Thereafter, it is liquefied by cryogenic cooling with the help of latest plate and fin, high efficiency heat exchangers and expanders. Then, the liquid air gets separated into oxygen, nitrogen and various insert gases in the air separation column.

FEATURES :

• Easy installation and commissioning
• Low power consumption due to Low pressure (5 to 7 Bar) process
• Low maintenance
• Fully automated air cooled design Rotary Air Compressor
• Nitrogen output with high purity up to 5 PPM
• CE certified product with design as per European Gas Association guidelines for ASP's
• Cryogenic expansion of air for cooling via Expansion Turbines
• No special civil foundation required for any part of the plant
• Hydrocarbon vapor level reduced below 0.003 PPM to ensure safe operation

SCOPE and SUPPLY :

Air Compressor : Rotary air compressor (screw type) is used in smaller plants with size up to 500m3/hr & 1000m3/hr. Centrifugal compressor is employed in big plants with size up to 40000 m3/hr.

Air pre cooling system : Air separation plants use a chilling system in air pre-Cooling systems.

Air purification system : Molecular sieve is used in the air purification system to separate the CO2 & moisture from the process air at low- Pressure.

Rectification column : The unit in cold box is all low pressure technology. This unit employs the latest state of the art plate & fin exchanger, condenser and sub- coolers. The column is supplied as a packed unit complete with all the control systems including digital flow- meters, temperature, and pressure available with high purity up to 2-3 ppm nitrogen as a second product without loss in oxygen production.

Expander : Expander is used for providing cooling to the air for the liquefaction process. On being braked by a booster, it diminishes the expanded air volume, stabilizes the upper columns working condition and reduces power consumption.

Computer control : All the plants can be configured for automatic operation through a PC. The procedure requires out switching valves of German or Japanese and motorized cryogenic valves on cold box.

Applications :

• OIL & GAS
• BEVERAGE INDUSTRY (COCA COLA , JUICE BOTTLING )
• GLASS INDUSTRY
• FREEZING SEAFOOD
• NITROGEN REFINERY
• TUNNEL FREEZING
• & MANY OTHERS
