Basic Principle:
The air separation plant is a plant recovering oxygen and nitrogen from air simultaneously. It advance low pressure technology process of Boschi Italy using Rotary screw compressor (or low oil free piston compressor)and turbo expanders. The feed air entering the Molecular Sieve purification system employed to remove the moisture and Co2 from the process air. The air is liquefied by cryogenic cooling using latest plate and fin high efficiency heat exchangers and turbo ex-panders. The liquid air separates into oxygen nitrogen and inert gases in the air separation column.

Main Components

1.Air Compressor:

Rotary air compressors screw type can be used for smaller size plants upto 500m3/hr & 1000m3/hr. Centrifugal compressor can be used for higher size plants.

2. Air pre cooling system:

Air separation plants adopts chilling system in all air pre-cooling systems.

3. Air purification system:

This system beds of molecular sieve are used in the air purification system, it remove the Co2 & moisture for the process air at low-pressure.

4. Rectification Column:

The unit in cold box are all low pressure technology. This unit employs the latest state of the art plate and 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, pressure available with high purity upto 2-3 ppm nitrogen as a second product without loss in oxygen production.

5. Turbo-expander:

Turbo-expander is used for giving cooling to the air for the liquefaction process and braked by booster, so as to reduce the expanded air column,stabilize the upper columns working condition and reduce power consumption. The turbine expanders have complete trouble free working and long life and reliability.

6. Computer Control:

All the plants can be configured for automatic operation through a PC this will use a out switching valves of German or Japanese and motorized cryogenic valves on cold box.

	Nitrogen Cylinder Filling Plants

Item Code: Medium-Capacity-Filling-Plants

Range: 1,000 TO 10,000M3/hr.
Purity oxygen-99.6% .Nitrogen-99.99% or 3PPM
Operating Air Pressure- 0.6 TO 0.7Mpa

This air separation plant mainly includes:

• air filter system
• air compressor system
• air pre cooling system
• Molecular sieve purifying system
• rectifying column system, nitrogen & oxygen compress and storage system, instrument control system, electric control system. Etc.

Air filter and compression
Air enters the self cleaning air suction filter, after being removed of dust and other mechanical contaminants in it, then enters main air compressor, after compression air then enters the after cooler.

Air cooling and purifying
Air is cooled in the Pre-Cooling System before enters mole sieve adsorber, Air which enters the evaporator of the Pre-Cooling System is cooled by the refrigerant.

Mole sieve purifying system includes two mole sieve adsorber and Steam heater or Electric heater. The mole sieve adsorber adsorbs water, CO2 and some hydrocarbon in the air, one mole sieve adsorber is regeneration while another one is work.

Air rectification
Air from adsorber is divided two stream: one stream enter directly main heat exchange, then enter lower column after cooled, the second stream enter main heat exchanger to cool after compressed by booster end of the expander and cooled by after cooler, then enter upper column after expanded by the expander.

The content of nitrogen will increase through rising gas connect with the reflux. Needed reflux liquid nitrogen is from condensate evaporator in the top of lower column, oxygen will be evaporated and nitrogen will be condensed in here.

• Lower column production as following from the top down:
• Pure liquid nitrogen
• Poor oxygen liquid air with 20%O2
• Rich oxygen liquid air with 36.5%O2

All production in the lower column after sub cooler enter upper column as its reflux.Production of upper column as following from the top down:

• Waster nitrogen at the top.
• Liquid oxygen at the bottom

Direction which all production of upper column go Waster nitrogen is reheated to design temperature out of the cold box by main heat exchanger and sub cooler after drawn from the top of upper column, one steam is regenerated by molecular sieve absorber, the other is taken in water cool column to cool water.

Purity: Oxygen gas of 99.6% purity can be produced and *pure nitrogen of 99.9% upto 3ppm is produced.
without any los of the oxygen production. **voltage and frequency as per the country of installation.

Main Performance of the plant:

A. Oxygen purity 99.6% at 150-160 Bar(2200PSIG) for Oxygen cylinder filling
B. High purity Nitrogen 99.99%(ppm optional) or cylinder filling.
