UBT SERIES PLANT SPECIFICATIONS-40% LOWER ENERGY CONSUMPTION

Basic Principle

Industrial Oxygen Plant• 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 by rotary air compressors.
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
Product StorageFor Gas: The final product in the form compressed Oxygen/Nitrogen goes to the high pressure oxygen cylinders at 150 bar or upto higher UPTO 200 BAR as required. OR for pipeline supply or captive consumption.
