Oxygen purity 99.6% at 150-160 Bar (2200PSIG) for Oxygen cylinder filling
High purity Nitrogen 99.99% (ppm optional) or cylinder filling.
NOTE: There is no loss of oxygen Production when producing high purity nitrogen.
Air separation is CRYOGENIC TYPE with low-pressure cycle of 7 Kg/cm2 with air separation by liquification. This cycle utilize an Expansion TURBINE to give the cold calories at (-)1 80o C. The cold box is supplied as a complete package unit with control panel and insulation.
Construction Materials for Air separation plants
The materials used in an air separation plant are exposed to wide range of temperatures, pressures, and purities during operation. Materials are selected that are compatible with the expected condition including normal operation, startup, shutdown, and process upsets.
For the oxygen system to operate safely, all parts of the system should be reviewed for compatibility with oxygen under all conditions they will encounter. The system is designed to prevent oxygen combustion by
- Selecting the optimum cryogenic grade material.
- Operating within the designed pressure, temperature, and flow limits; and
- Obtaining proper cleanliness.

Basic Principle
The UBT series air separation 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 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 air separates into oxygen & liquid nitrogen in the air separation column with final product being sent for pipeline application or stored into cylinders at the required pressure.
Process Description
STEP 1 - Air Compression
In the first stage air is compressed at a low pressure of 5-7 bar (Gas plants) to 10 Bar (liquid plants). 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 reciprocating compressor).
STEP 2 - Air Pre-Cooling
The second stage of the process uses a low pressure refrigerant (R-407A as per CE regulations) for pre-cooling the processed air to temperature around 12 deg c before it enters the purifier.
STEP 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.
STEP 4 - Separation of Liquid Air into Oxygen and Nitrogen in 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.
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. Air gets liquefied when it enters the air separation column & gets separated into oxygen & nitrogen by the process of rectification.
Oxygen is available in gas or liquid form (as per requirement) at the outlet of the ASU at a purity of 99.6%. Nitrogen is also available at the outlet as a second product at purity of 99.99% upto 3ppm simultaneously without loss of oxygen product (or as specified).
STEP 5 - Product storage
For Gas: 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.

Data for "Pure Nitrogen plants"
Introducing the Boschi Italy UBTN series pure nitrogen plants for process industries
Nitrogen is the largest constituent of the Earth's atmosphere (78.082% by volume of dry air, 75.3% by weight in dry air). Nitrogen gas is an industrial gas produced by the fractional distillation of liquid air and when supplied compressed in cylinders it is often called OFN (oxygen-free nitrogen).
Nitrogen gas has a variety of applications, including serving as an inert replacement for air where oxidation is undesirable
- As a modified atmosphere, pure or mixed with carbon dioxide, to preserve the freshness of packaged or bulk foods (by delaying rancidity and other forms of oxidative damage)
- In Oil refineries for drilling, nitrogen blanketing & purging.
- For Pneumatic testing of pressure vessels in manufacturing industry.
- Beverages bottling as a preservative.
- In ordinary incandescent light bulbs as an inexpensive alternative to argon.
- The production of electronic parts such as transistors, diodes, and integrated circuits
- Dried and pressurized, as a dielectric gas for high-voltage equipment
- The manufacturing of stainless steel
- Used in military aircraft fuel systems to reduce fire hazard,
- Filling automotive and aircraft tires due to its inertness and lack of moisture or oxidative qualities, as opposed to air.
- Used as a propellant for draft , and as an alternative to or together with carbon dioxide for other beverages.
The Universal Boschi Pure Nitrogen plants are designed for all applications with the Latest Low Pressure process incorporating Rotary Air Compressor (oil free design) and expansion turbines to achieve Nitrogen output in both gas and liquid form at High Purity.
