    UBTL Series- Liquid Oxygen Nitrogen Plants
    UBTL Series 3d Layout Liquid Oxygen Plants

    Basic Principle

    The UBTL series air separation plant recovers oxygen and nitrogen from air simultaneously via Low pressure cryogenic Distillation process. It’s 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 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.

    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 w
