Salient Features:

A few of the latest technological features incorporated into the Oxygen & Nitrogen plants are listed below.

  • Purity of Oxygen produced from all plants is minimum 99.6% and Nitrogen Purity is available up to 1 PPM (Depending upon requirement of the customer).
  • All plants use “Oil free” rotary screw /centrifugal oil compressor working between 0.6 to 1.0 mpa.
  • All plants incorporate Aluminum Brazed exchangers and packed columns for high efficiency.
  • Turbo expanders (Oil or Air Bearing) for trouble free operation.
  • All plants above “500” are supplied with automatic PLC control.
  • Engineering support along with complete quality control is provided by our company.
  • We provide qualified engineers for Supervision, Installation and start up of all our plants as well as training of manpower at customers’ site.
  • Very low power consumption with proven performance and virtually Zero maintenance required for the machines.
  • Purity of Nitrogen is very high i.e. 99.99%
  • No loss in the production of Oxygen while producing high purity Nitrogen.

  • AIR SEPARATION UNIT: This Unit employs a front-end two bed pressure swing adsorption system which is used to remove impurities from the air feed. The Cold Box plays the main role in the Oxygen/Nitrogen plant as this is the equipment which separates the gaseous mixture of oxygen and nitrogen. This is done by means of Liquification of air to a temperature of minus 1900C in the Double Rectification Stainless Steel Column.

    Air Separation Unit houses all the instruments (such as Heat Exchangers, Sub Coolers, Distillation Columns and Condensers all made in Stainless Steel) responsible for the sub-zero cooling of the air thus giving it the name COLD BOX.

    Air Separation Unit is of CRYOGENIC TYPE operating at extremely low-pressure of 7 Kg/cm2. The separation of gases is done at liquification state.
  • EXPANSION TURBINE: The expansion turbine or Turbo expander is a centrifugal or axial flow turbine through which a high pressure gas is expanded to produce work that is typically used to drive a compressor. Because work is extracted from the expanding high pressure gas, the expansion is isentropic and the low pressure exhaust gas from the turbine is at a very low temperature, often as low as 200 K (-100 °F) or less.

    The turbo expander has a composite metal shaft with a compressor wheel attached to one end of the shaft and an expander wheel attached to the other end of the shaft. Both the wheels are completely detached from one another.

    Along with the common shaft a sealing system is used for the prevention of the process fluids present at each wheel from getting contact with leakage along the shaft. We use a gas seal system as a sealing system in our Plant. The advantage of using a gas seal system is that the sealing fluids cannot leak into and accumulate in downstream equipment.
