The process used is cryogenic which involves deep refrigeration/cooling of Air below zero to minus 190 degree centigrade to liquid form and then AIR SEPARATION into liquid oxygen and liquid nitrogen. The process cycle is low pressure cycle and low power consumption and is proven technology in the last 30 years all over the world.

• Air Compressor

  Air Compressor is used to compress the atmospheric air.
• Air Purifier/Process Skid is used to purify the air by cooling the air in an after cooler and nitrogen cooler with additional chiller. Traces of oil are removed in a high efficiency filter/oil absorber. Carbon dioxide is removed by the MOLECULAR SIEVE DRYER.
• Expander/Expansion Engine is used along with exchangers & expansion valves for cooling and liquefaction of AIR.
• Air Separation Unit/Cold Box is used for the separation of Liquid Air by means of a double Rectification Column consisting of upper and lower column.

• Production of Bone dry and high purity - Industrial and medical grade oxygen gas purity 99.6% up to 155 bar (200 bar optional) by Liquid Oxygen Pump.
