Universal Boschi in collaboration with
manufactures & suppliers premium quality oxygen plants of all sizes
ranging from 20m3/hour to 10,000m3/hour ING.L.A. BOSCHI ITALY since 1930.
Our oxygen/nitrogen plants are being manufactured as per the latest
technology & design of the Company ING. L. & A., BOSCHI, ITALY since
1930. This technology has been proven all over the world for its working
efficiency & trouble free operation. We have manufactured over 300
plants since last 30 years since 1985 at New Delhi and supplied to over 40

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
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.
||Main Heat Exchanger
1. Air Compressor-Low Pressure
Air is compressed at a very pressure of 5-7 bar (kg/cm2). 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
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 processed air before the air enters Air Separation Unit.
4. Cryogenic Cooling of Air by Turbo (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
Oil free, moisture free and Carbon Dioxide free air enters into low
pressure fin type HEAT EXCHANGER where the air is cooled below sub zero
temperatures by air expansion process in the turbo expander.
Air gets liquefied when it enters the air separation column & gets
separated into oxygen & nitrogen by the process of rectification.
Nitrogen gas is available at the outlet at purity of 99.99% upto 3ppm (lppm
in some models)
Liquid nitrogen is also available alongwith the pure nitrogen gas products.
