Oxygen / Nitrogen Plants


1. AIR COMPRESSOR- ROTARY
  Air Compressor
This is a single-stage machine, balance opposed lubricated, water-cooled and air cooled heavy duty designed for 24 hours continuous operation ,horizontal with rugged intercoolers to give normal discharge conditions. This can be single frame or a primary and secondary compressor. The increased no. Of stages also improves the volumetric efficiency of the compressor and reduces B.H.P. for alternative oil free reciprocating compressors The inter stage temperature are low and therefore no carbon formation.

Air Filter (Part of Air Compressor):
Dry type provided by the air compressor manufacturer.

A good air compressor with exceptional quality is crucial for oxygen and nitrogen plant in terms of reliability maintenance, compressing capacity, product quality and efficiency. The discharge pressure of air compressor for air separation plant is usually within 7 to 10 Bar, so there exists a wide selection of Atlas copco rotary screw type and oil free screw type, Centrifugal type and Rotary screw type. All the core capacity required for the oxygen plant is generated by the high efficient plants and reduce power.

  Expander Cryogenic

4. Expander CRYOGENIC
Single cylinder expansion engine, hydraulically operated with variable cam forautomatic control of pressure and temperature, this is also equipped with ball type valve at inlet and outlet which is proof for trouble free operation for years together complete with electric motor.
The expander is a rotary machine running on gas bearing.
This is used to provide cooling for the liquefication of air at minus temperature.

The turbine works to increase the flow rate of the compressed gas through a nozzle meanwhile; the speeded gas drives the wheel & output power through the rotor. During the procedure, both the pressure and temperature of gas lowered down, thus to provide cold capacity. In modern air separation plant, the cold capacity by turbine takes about more than 90% of entire cold capacity needed.


  Liquid Oxygen Pump
5. LIQUID OXYGEN PUMP
There is one liquid pump, namely for oxygen. The oxygen is being pumped in liquid form and thus eliminated unnecessary equipment such as gasholders and Oxygen compressor. This pump has special design with SS jacket Argon welded with special jacket for insulation to avoid cold loss during pumping. This pump has special seal to prevent any oil carry over during operation. The oxygen purity is high and is bone-dry because this has been provided with special types of seals designed specially for this purpose complete with electric motor vee belts, fly wheel, pulley and guard.
