UNIVERSAL BOSCHI is a global manufacturer and exporter of Oxygen/Nitrogen Gas Plant with Latest Cryogenic Technology Stainless Steel Column and Atlas Copco Air Compressor.

We are manufacturing and exporting of Oxygen/Nitrogen Gas Plants, which are technologically very advanced. Our oxygen/nitrogen gas plants are being manufactured and supplied 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.

Oxygen Nitrogen Gas Plant for Cylinder Filling

Our Oxygen/Nitrogen Gas Plant recovers oxygen and nitrogen from air simultaneously via Low pressure cryogenic Distillation process. Its design is based on the advanced low pressure technology process of Boschi Italy using rotary screw compressor and turbo expanders. The feed air enters the Molecular Sieve purification system employed to remove the moisture and C02 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 liquid oxygen & liquid nitrogen in the air separation column with final product being stored into liquid tanks at the desired pressure.

SPECIAL FEATURES:

Universal Boschi is a leading manufacturer and supplier of cylinder filling oxygen plant. Our plants are designed and developed by using the latest technology in order to make them perform as per the plants of international standard. With the technical collaboration of ING. L. & A. BOSCHI of Italy, our company develops and designs automatic and efficient plants. Our association with Dr. Boschi of Italy has helped immensely to manufacture the plants which are in compliance with the international standards and CE certification. Our cylinder filling oxygen plant is unmatched in the industry.  

Basic Principle

Our cylinder filling oxygen 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.

Process Description

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.

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 150 bar or upto higher as required. It is required for pipeline supply, captive consumption or for liquid plants to fill in cryogenic liquid tanks.
