AIR SEPARATION PLANT:
We are a leading company for designing, manufacturing and supplying different capacity air separation plants. Our company was incepted in 1985 in the national capital region of New Delhi. We are technologically associated with ING. L. & A. BOSCHI of Italy in order to get the best technology. Our designs are based on the process cycle of Linde & Claude which had been perfected by Dr. Boschi of Italy and his company ING. L. & A. BOSCHI of ITALY in 1930. The air separation column separates Liquid Air into Oxygen and Nitrogen. Our components are known for their efficiency & long life.
• Capacity: 50m3/hr to 5000 m3/hr
Our Air separation plant is a plant recovering oxygen and nitrogen from air simultaneously. It employs low pressure technology process of Boschi Italy along with Rotary screw compressor (or low oil free piston compressor) and turbo expanders. The feed air entering the Molecular Sieve purification system used to disappear 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 gets separated into oxygen nitrogen and inert gases in the air separation column.
1. Air Compressor-Low Pressure
Air is compressed at a low pressure of 5-7 bar (0.5-0.7mpa). Air can be compressed at such low pressure by latest rotary compressor (Screw/Centrifugal Type latest technology is used in place 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 goes inside the purifier.
3. Purification of Air by Purifier
The air goes inside purifier holding twin Molecular Sieve driers, working alternatively. The Molecular Sieves remove the Carbon dioxide & moisture from the process air before the air gets into the Air Separation Unit.
4. Cryogenic Cooling of Air by Turbo (Expander)
The air must 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 goes inside the low pressure plate fin type Heat exchanger where the air is cooled below sub zero temperatures by air expansion process in the turbo expander. Owing 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 reaches at the air separation column & gets separated into oxygen & nitrogen by the process of rectification.
