 Process Description:

 The process adopted to produce oxygen and nitrogen is called liquefaction and fractional distillation of air inside the air separation unit. Compressed & purified air is expanded and liquefied in this process of expansion and cooling in an expansion engine and expansion valves. The expanded and cooled air from expansion engine and expansion valves will enter the lower part of the distillation column in partial liquid form. The oxygen and nitrogen have different boiling points. Since nitrogen is more volatile is drawn out of the distillation column in vapour form and oxygen is collected in condenser. 

The Liquid Oxygen Compressed by Liquid Oxygen Pump & passed through Heat Exchangers, Gasified, filled at 150 Kg/Cm²g pressure to the Cylinders. In the same manner the Liquid Nitrogen can also compressed, Gasified and filled in N2 Cylinders.

Along with Drier Control MSB Panel, fitted with DUST FILTER, ALUMINA FILTER, CERAMIC FILTER & HIGH EFFICIENCY CARBON FILTER.

  • At Oxyplants  we use two columns with molecular sieves to ensure continuous production.
  • Dry compressed air is blown through a valve to the vessel where the pressure is built to reach 40 to 45 bar (g). Nitrogen is tied to a molecular sieve during the building of pressure, and the oxygen is allowed to pass through to the accumulation tank.
  • While pressure is build in one vessel, the second remains without pressure.
  • A part of the produced gas is used for regeneration of the molecular sieve.
  • For Oxygen, Zeolite type 13X is used. The molecular sieve is fully regenerative and has a life span on to 60.000 operation hours.

DISTRIBUTION ELECTRIC PANEL (L T Panel)

to control the electric distribution to different motors & heaters for complete plant.

We supply Electric Distribution Panel (Siemens /ABB) as per the Customers choice.

This new generation of Panel Board products represents the high level of engineering innovation expected. With flexibility and strength added to the existing rugged and durable Panel Board, Panel Boards are extremely easy to install. These newer designs also simplify wiring and reduce material requirements, saving additional installation time. new technology circuit breakers offer significant benefits and better coordination with upstream breakers that help meet 2011 NEC® Code requirements for selective coordination.


ELECTRICAL MOTORS (AC Low Voltage)

These motors are used to drive Air compressor, Expansion Engine, Liquid Oxygen Pump, Liquid Nitrogen Pump, Cooling Tower. 

We at Oxyplants use Siemens/ABB make AC Low Voltage Motors. Our low voltage motor products cover a performance range from 2 to 800 kW. Advantages of our AC motor systems are many: they are highly efficient with a positive energy balance; they come with explosion protection to meet high safety standards; and they conform to IEC or NEMA standards. The many standard features that come with every Siemens/ABB low voltage motor ensure the highest possible cost-effective operation.
