Basic Principle
The air separation plant is a plant recovering oxygen and nitrogen from air simultaeously. 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 expanders.The liquid air separates into oxygen nitrogen and inert gases in the air separation column.

Process Description
1. Air Compressor
Air is compressed at a low pressure of 5-7 bar (0.5-0.7mpa). Air can be compressed at such low pressure by trouble free rotary compressor (Screw / Centrifugal Type advanced technology is employed in lieu of old bulky piston compressor).

2. Pre Cooling System
The second stage of the process uses a low pressure refrigerant for pre-cooling the processed air to temperature around 12 deg c before it enters the purifier.

3. Purification of Air by Purifier
The air enters a purifier consisting of twin Molecular Sieve driers, working alternatively. The Molecular Sieves remove the Carbon dioxide & moisture from the process air before the air enters Air Separation Unit.

4. Cryogenic Cooling of Air by Expander
The air has to be cooled to sub zero temperatures for liquification & the cryogenic refrigeration & the cooling is provided by highly efficient turbo expander, which cools the air to temperature almost below -165 to-170 deg C.

5. Separation If Liquid Air Into Oxygen and Nitrogen by Air Separation Column
Oil free, moisture free and Carbon Dioxide free air enters into low pressure plate fin type Heat exchanger where the air is cooled below sub zero temperatures by air expansion process in the turbo expander. Due to the excellent thermal efficiency we can achieve a temperature difference delta t as low as 2 deg c at the warm end of these exchangers.

Air gets liquefied when it enters the air separation column & gets separated into oxygen & nitrogen by the process of rectification.

Oxygen is available at the outlet of the ASU at a purity of 99.6%.
Nitrogen is also available t the outlet as a second product at purity of 99.99% upto 3ppm simultaneously without loss of oxygen product.

6. Compression of Oxygen filling in the Cylinder
The final product in the form compressed Oxygen/Nitrogen goes to the high pressure oxygen cylinders at 1 50 bar or upto higher as required.. Or for pipeline supply or captive consumption | Or for liquid plants to fill in cryogenic liquid tanks.
