Universal Industrial Plants Mfg. Pvt. Ltd. is a leading manufacturing and supplying company, specialized in providing Low pressure Air Separation Plant, Oxygen Plant and Nitrogen Plant of sizes, ranging from 20 m3/hour to 500 m3/hour, such as Cryogenic Tonnage Nitrogen Plant, Air Separation Plant, Cryogenic Tonnage Oxygen Plant and Liquid Oxygen Nitrogen Plant. ING. L. A. Boschi of Italy in collaboration with our company has shared the design and technology for the mentioned plant.
Quality: UNIVERSAL BOSCHI is a ISO 9008:2015 and CE certified organization that stands by the quality of products delivered to customers.
Main Performance of The Plant:
Capacity Range (Cu. Mtr/hr) : 50 to 50.000m3/hr
Nitrogen Pressure out of Column (bar) : 7 bar
A. Oxygen gas of 99.7% purity at 150-160 Bar (2200PSIG) or upto 200/300 bar as required for filling the oxygen cylinder.
B. High purity Nitrogen 99.99 %( 3ppm optional) or cylinder filling.
NOTE : There is no oxygen production loss, during the production of high purity nitrogen.
We have included latest technological features into the Oxygen & Nitrogen plant, such as:
Plant produces oxygen of minimum 99.7% purity and nitrogen purity can be achieved up to 1-3 PPM (Depending upon customer requirement).
The plant is integrated with "Oil free" rotary screw /centrifugal oil compressor working between 5-7 bar.
The efficiency of the plant is elevated by incorporating aluminum brazed exchangers and packed columns.
There are turbo expanders (GAS Bearing) for hassle free operation.
The plant above "500M3/HOUR" capacity are provided with automatic PLC control.
Our company provides engineering support together with complete quality control.
Qualified engineers are here to help you with supervision, installation, plant start-up and manpower training.
The plant consumes low power, while performing at level best without requiring any maintenance.
Customers can completely rely on the quality of oxygen gas produced for hospital and industrial use.
Process Description for Oxygen – Nitrogen Low Pressure Oxygen/Nitrogen Plants:
1. COMPRESSION OF ATMOSPHERIC AIR
Air is compressed at 5-7 bar (kg/cm2) pressure. Rotary air compressor makes it possible to compress the air at such low pressure.
2. PRE COOLING SYSTEM
The processed air is pre-cooled to temperature around 12 deg C using a low pressure refrigerant, before the air enters the purifier.
3. PURIFICATION OF AIR BY PURIFIER
The air is then passed to purifier with alternatively working twin molecular sieve driers. These sieves eliminate moisture and carbon dioxide from the processed air, before the air enters intp the air separation unit.
4. COOLING OF AIR BY TURBO (EXPANDER)
Turbo expander cools down the air to temperature almost below -165 to-170 deg C, needed for liquefaction & the cryogenic refrigeration.
5. SEPARATION IF LIQUID AIR INTO NITROGEN & OXYGEN BY AIR SEPARATION COLUMN
Air free from moisture, oil and carbon dioxide, enters into low pressure heat exchanger of fin type, where it is cooled below sub zero temperatures in the turbo expander by air expansion process. In the air separation column, the air is liquefied and separated into nitrogen and oxygen by the rectification process. Oxygen as pure as 99.6% is available at the outlet of the ASU. Nitrogen as pure as 99.9% up to 3ppm is available at the outlet as a second product, without loss of oxygen product.
6. Compression of oxygen &filling of in cylinders
The compressed nitrogen// oxygen is passed into the high pressure oxygen cylinders at 150 bar or up to higher as required. Liquid oxygen pump does this in same models. We can use compressor which is oil and water free.
Pre – Cooling system
Universal Boschi Purifier
Fully Automatic Rotary air compressor
Air separation Unit
Argon Recovery Plants
Argon is recovered above 1000M3/Hour Oxygen Plants by a technique that employs complete rectification without making use of the Hydrogen and De-Oxo unit, thus saving further on power costs, operational costs and investment. This makes Boschi design plant versatile and cost-efficient, all thanks to years of research and development.
