Nitrogen Gas Generator

Nitrogen gas is called as the largest industrial gas because of its extensive use in wide range of industries including metal, steel, chemical, pharmaceutical, medical and food packaging.  It is found abundantly throughout the universe and the earth’s atmosphere comprises of 78% nitrogen. For meeting industrial requirements, industries use nitrogen generators which we manufacture using the best cryogenic distillation technology. Also, we use the best materials and components in the making of the nitrogen machinery.  Since the focus of entire business is satisfaction of customers, we ensure that our machines function optimally in delivering high purity nitrogen. We are trusted nitrogen plant manufacturers that design and fabricate the plants that are reliable, durable and high performing.

Installing onsite nitrogen gas generators will deliver you guaranteed supply of oxygen 24*7. No more fretting over erratic supply of nitrogen gas from industrial gas subscribers. It is assured that your manufacturing operation will never suffer because of shortage of the non-reactive gas.  After installing the nitrogen machinery, you will be able to generate as much of it as you want without any interruption. And, you can store the gas as well for future contingencies. Though the machinery is capital-intensive but it is very beneficial investment for the growth of your business.  Return on investment is two years and after which it all your profits for over two decades. Our nitrogen generators come in different sizes and capacities ranging from 20m3/hour to 500m3/hour. We have been awarded ISO 9008: 2015 and CE certification for our strict compliance with quality control.

Nitrogen & its Various Uses

Nitrogen is very vital gas for various industries including chemical where it is used for making fertilizers, nitric acid, nylon, dyes, and explosives. The gas is known for its inerting properties making it ideal for preserving food and manufacturing diodes and transistors. The largest industrial gas is used on a large scale in annealing stainless steel and various other products used in the generation of steel. Annealing is a heat treatment that making it easier to work on steel. It is used for freezing foods and helping them to maintain texture, flavor, color and moisture. Various other applications include:

  • Storage of sperm, eggs and other cellular materials
  • Beverage industry (coca cola ,juice bottling )
  • Glass industry
  • Freezing seafood
  • Nitrogen refinery
  • Tunnel freezing

Salient Features of Nitrogen Gas Generator

  • Easy installation and commissioning
  • Low power consumption due to Low pressure (5 to 7 Bar) process
  • Low maintenance due to no reciprocating parts
  • Fully automatic air cooled design Rotary Air Compressor
  • Nitrogen output at high purity up to 5 PPM
  • CE certified product with design as per European Gas Association guidelines for ASP’s.
  • Cryogenic expansion of air for cooling via Expansion Turbines
  • No special civil foundation required for any part of the plant
  • Hydrocarbon vapor level reduced below 0.003 PPM to ensure safe operation

Scope & Supply of Nitrogen Gas Plant

  • Air Compressor : Rotary air compressor screw type can be used for smaller size plants upto 50 m3/hr & 1000 m3/hr. Upto 40000m3/hr. Centrifugal compressor can be used for higher size plants.
  • Air pre cooling system: Air separation plants adopt chilling system in all air pre-Cooling systems.
  • Air purification system: Molecular sieves are used in the air purification system to remove the Co2 & moisture for the process air at low- Pressure.
  • Air separation column: (Air separation column-cold box) consists of outer steel casing, Main heat exchanger, liquefier, Bottom column, Top column, Condenser, Sub-cooler, Liquid oxygen & nitrogen filter. Cooling pipe line, insulation material, Digital electronic temperature indicator & scanner, PT 100 sensor, DP gauge monometer, Expansion valve with long stem type with pointer & index & wheel -1 set.
  • Expander: Expander is used for giving cooling to the air for the liquefaction process and broken by booster, so as to reduce the expanded air volume, stabilize the upper columns working condition and reduce power consumption. The turbine expanders have complete trouble free working and long life and reliability.
  • Control Panel: Nitrogen gas plants can be configured for automatic operation through a pc. This will use out switching valves of German or Japanese and motorized cryogenic valves on cold box.
