Argon

Industry  Application  Description 
Analytical Laboratories  Plasma  Supply for Inductively Coupled Plasma (ICP) units for analyzing non-organic materials 
Electronics  Crystal Growth  Used as an inert atmosphere for silicon crystal growth 
Manufacturing Body – Welding Welding processes use argon for steel.
Manufacturing Welding Most commonly used shielding gas, and is the only truly inert gas commonly used in welding.

 

Carbon Dioxide

Industry  Application  Description 
Biotechnology Metabolic Gases  Process Requirement, Performance, Reliability
Chemical  Cooling of Exothermic Reaction  Cooling chemical reactions in a jacketed reactor. 
Food  Injection   Wastewater pH adjustment of discharge cleaning water 
Food  Deboning  Deboning of beef and/or chicken by cooling the meat on the bone to embrittlement temperature and fracturing off 
Manufacturing Welding CO2 decomposes to CO and O2 at welding temperatures, producing an oxidizing effect similar to a combination of argon plus 0-5% O2. 
Wastewater Treatment Allows much more accurate pH control than any acid system

 

Nitrogen

Industry  Application  Description 
Analytical Laboratories  Specimen Preparation  Preparation of some specimens prior to testing  
Analytical Laboratories  Cold Traps  Liquid nitrogen is used in a cold trap to capture impurities in a gaseous line.  
Chemical  Inerting  Inerting of chemicals in tanks and in transport 
Chemical  Cooling of Exothermic Reaction  Cooling chemical reactions in a jacketed reactor. 
Chemical  Vapor Recovery  Recovery of volatile vapors from processes by cooling the vapor to below its boiling temperature and turning it to liquid, them recovering the liquid. 
Chemical  Pipe freezing  Liquid nitrogen is put through custom jackets on the outside of a pipeline to freeze the liquid inside and create a plug.  These plugs are located on either side of a break to stop flow so the line may be serviced. 
Chemical  Vacuum Breaking   Gas is used to break vacuums in reactor tanks to prevent oxygen from contaminating the chemical 
Electronics  Cleaning  Nitrogen is used to clean the surfaces of fiber optic strands prior to connecting to one another 
Electronics  Soldering  ICB (Interconnecting Circuit Boards) are soldered under a nitrogen atmosphere to prevent oxygen contamination 
Food  Sparging  Sparging non-carbonated drinks with nitrogen to remove dissolved oxygen 
Food  Pressurizing  Pressurizing of non-carbonated beverages in aluminum cans 
Food  Deboning  Deboning of beef and/or chicken by cooling the meat on the bone to embrittlement temperature and fracturing off 
Food  Sausage Cooling  Cooling sausage blending operation so fat does not liquefy. 
Food  Batch Cooling  Batch cooling of ground beef, pork or poultry to retain fat content. 
Food  Cryo-Grinding  Cryogenic grinding of high oil content or difficult to grind spices 
Food  Extrusion Cooling  Cooling of extruded foods to increase production 
Food  Pneumatic Cooling  Liquid nitrogen is injected into a bulk products transfer line to cool products such as flour. 
Food  Mold Cooling  Cooling of molded candy and gum for quick release from mold 
Manufacturing Vulcanization-Tires Vulcanization is a curing process that makes natural and synthetic rubber harder and more wear resistant.
Manufacturing Body – Heat Treating Heat treating processes use hydrogen and nitrogen in annealing furnaces to strengthen and improve formability of the steel. 
Manufacturing Heat Treating Nitrogen-based protective atmosphere for their furnaces. 
Pharmaceuticals Reactor & Fluid Cooling  Chemical Synthesis, Process Development, Active Pharmaceutical Ingredients
Pharmaceuticals Lyophilization / Freeze Drying Steriles, Vaccines, Process Development & Manufacturing
Pharmaceuticals Vent-gas Recovery  Environmental Compliance, Cost Reduction
Refining Production Used to inert hydrocarbon systems

 

Oxygen

Industry  Application  Description 
Biotechnology Metabolic Gases  Process Requirement, Performance, Reliability
Energy Production Cost-effective and reliable means to decrease NOx emissions
Manufacturing Body – Combustion Combustion processes use oxygen to melt scrap, refine the steel, and heat the furnaces that reheat steel slabs. 
Manufacturing Body – Heat Treating, Welding & Combustion Welding processes use carbon dioxide for auto bodies.
Manufacturing Oxy-Fuel Oxy-Fuel Conversion of Glass Furnaces
Manufacturing Welding O2 is added to shielding gas, where it helps produce a more stable arc, improves wetting of the weld edges and reduces weld spattering.
Pharmaceuticals Fermentation Productivity, Yield
Refining Production Oxygen is used inside refineries to enhance combustion processes 
Wastewater Treatment Respiration of the micro-organisms that convert organic wastes into harmless carbon dioxide and water
