Common Applications
Beer & Wine Manufacturing & Storage
Breweries and wineries take great care to prevent oxidation during all processing steps and packaging to enhance product quality. Nitrogen can also provide an inert atmosphere during the mashing and lautering operations. Increasing the nitrogen levels in the finished product to enhance foam characteristics is also common

Chemical Processing
Nitrogen is used to create an oxygen-deficient environment for use with oxygen-sensitive chemicals reducing safety hazards. It is used to propel liquids through pipelines; and in the manufacture of ammonia.

Electronics
Nitrogen prevents oxidation while manufacturing semiconductors and printed circuit processes such as wave soldering. It is also used to enhance solvent recovery systems by eliminating the use of chlorofluorocarbons for cleanup.

Food Processing & Packaging
Nitrogen extends shelf-life in packaged foods by preventing spoilage due to oxidation, mold growth, moisture migration and insect infestation.

Injection Molding
In the gas injection molding process (GIM), nitrogen is injected under high pressure into the melted polymer and displaces the core of the molded part. This creates a void and reduces the amount of material used.

Metal Production
Nitrogen is used to protect metals such as steel, copper and aluminum during annealing, carburizing and sintering operations.

Metal Fabrication
Nitrogen is utilized as a purge gas with stainless steel tube welding. It is also used to support plasma and laser cutting systems. By using high purity (99.9% to 99.99%) nitrogen, it is possible to eliminate oxide edges and the need for additional handling labor.

Petroleum Refining
Nitrogen is used to maintain pressure in oil and gas reservoirs; to blanket storage tanks and product loading/unloading; to purge pipelines; and to strip volatile organic compounds (VOCs) from waste streams. Controlling VOC emissions helps refiners comply with U.S. Clean Air Act requirements.

Pharmaceuticals
Nitrogen is commonly used for blanketing and purging to protect volatile chemicals from oxygen and high purity gases, which are a required component of many analytical instruments.

Rubber Manufacturing
In the vulcanizing process, nitrogen is used to prevent surface deteriorations due to oxidation.


Why do you need a GN2 System
75% to 92% Cost Savings
Generating your own nitrogen can substantially reduce the cost of nitrogen consumption, and is the primary reason for the purchase of most GN2 systems.

The price of purchasing nitrogen in a gaseous or liquid form can vary from $2.88 to $0.35 per 100 ft3. The price range can be a result of volume consumption, type of product, location, or vendor. This cost is strictly for the gas or liquid delivered and does not factor additional supply costs such as:
  • Delivery Costs
  • Monthly Cylinder / Tank Rental Fees
  • Bulk Evaporative Loss
  • Handling and Purchasing Labor Costs
  • Additional Site Liability Insurance
A GN2 system will produce gaseous nitrogen at costs that ranges from $0.061 to $0.217 per 100 ft3. The price range is a result of local power costs, compressor efficiencies, and required nitrogen purity.

An average GN2 system has an (ROI) return on investment of 6 to 18 months. This rapid return enhances the financially attractive position of a GN2 system above and beyond the 75% to 92% base reduction in nitrogen cost.

Reliability
GN2 systems operate automatically and supply nitrogen on demand 24hours a day. A missed nitrogen delivery due to bad weather or clerical oversight can dramatically impact production costs.

Nitrogen Purity
GN2 systems can produce nitrogen purities from 95.0%to 99.99%. If your application can operate at lower purities the cost of production is reduced and can add to your overall reduction in nitrogen costs.

Safety
GN2 systems operate with no more liability than a standard compressed air system. With a GN2 system you yield the liability of handling 2,200 PSI cylinders or storing -320°F(-196°C) liquid nitrogen.

Experience
Great Lakes Air has over 25 years of experience manufacturing various types of standard and custom PSA (Pressure Swing Adsorption) systems for many industries such as: Petrochemical, Automotive, Mining, Defense, Pharmaceutical, Aerospace, Electronics, Food & Beverage, Steel Production, Medical Industry. The GN2 Nitrogen generator is a PSA system that separates the oxygen from a compressed air supply generating a continuous source of gaseous nitrogen.


System Operation
The earth’s atmosphere is comprised of approximately 78% nitrogen and 21% oxygen. Once atmospheric air is compressed, its pressure is increased while proportions of nitrogen and oxygen remain unchanged. Once the air is compressed it must be filtered and dried prior to its introduction to the GN2 system.

Step 1.
Inlet valves direct the compressed air flow into one of the two adsorption chambers (Right) where the CMS (Carbon Molecular Sieve) adsorbs the oxygen content while allowing the nitrogen to pass creating a high purity nitrogen stream that then exits the adsorption chamber and is stored in the nitrogen storage/buffer tank. The other adsorption chamber (Left) is depressurized to atmosphere through the exhaust valve enabling the CMS to release and expel any previously adsorbed oxygen to atmosphere.

Step 2.
Just prior to the end of the (Right) absorption cycle the exhaust valve on (Left) is closed and balance valves are opened to equalize pressure in the two adsorption tanks.

Step 3
The inlet valves are then inverted bringing the regenerated (Left) tower online to adsorb oxygen leaving a high purity nitrogen gas stream. The other adsorption chamber (Right) which was previously online adsorbing oxygen is depressurized so the CMS will release and exhaust any previously adsorbed oxygen to atmosphere.

Step 4
This cyclic action continues allowing the GN2 to produce a steady stream of high purity nitrogen gas. This process is commonly known as Pressure Swing Adsorption (PSA).

(CMS) Carbon Molecular Sieve
The adsorption component CMS is a non-polarity based adsorbent that uses a unique pore structure to preferentially adsorb oxygen molecules over nitrogen molecules. By adsorbing the oxygen from the process stream (Compressed Air) what remains can be virtually pure nitrogen. Because the product is a non-polarity based adsorbent, it’s hypothetical life is indefinite but realistically it has an industrial service life in excess of 10 years with proper maintenance.

Carbon molecular sieve is also widely applied in petrochemical industry, heat treatment industry, and electronic manufacturing as well as the food preservation.
