Argon Gas

Argon belongs to the family of inert and rare gases of the atmosphere. It is plentiful compared to the other rare atmospheric gases; 1 million ft3 (28 300 m3) of dry air contains 9340 ft3 (264 m3) of argon. Argon is colorless, odorless, tasteless and nontoxic. It is extremely inert and forms no known chemical compounds. It is slightly soluble in water. Argon is manufactured in air separation plants by means of fractional distillation after the liquefaction of air.

Application of Argon Gas In Industry

All of the major applications of Argon are related to the production, processing and fabrication of metals. The role of Argon is nearly always to exclude atmospheric air from contact with metal alloys. An example of this is as a purging gas to protect weld areas, such as the inside of pipes during welding.
The predominant gas used in shielding gases because it forms a very good shield due to the high density and total inertness.
Used on a wide range of ferrous and non-ferrous materials for welding and cutting.
Shielding gas for MIG and TIG welding processes and for plasma-cutting. Argon is used alone or mixed with other gases such as Helium, Carbon Dioxide, Oxygen, Nitrogen or Hydrogen. Each mixture is often specific to welding a particular material or to a particular process. For example, Argon is used as a shielding gas for TIG-welding aluminium, titanium and copper.
When MIG-welding ferrous materials, pure Argon is not an ideal shielding gas, as it produces an arc with poor cathodic rooting characteristics, large droplet size and therefore higher levels of spatter. For this reason, BOC recommends that Argoshield or Stainshield gases be used depending on the thickness and type of material being welded.

Nitrogen Gas

Liquid Nitrogen is a compact and readily transported source of Nitrogen gas without pressurization. Further, its ability to maintain temperatures far below the freezing point of water makes it extremely useful in a wide range of applications and industries

Application of Nitrogen Gas In Industry

Used for blanketing and purging applications to displace or dilute all unwanted gas or vapour
Widely used for reasons of safety and the prevention of product degradation in the chemicals and petroleum industry: Inerting reactors and storage tanks, Purging vessels and pipelines, Sparging, Pressure-transfer of liquids
Shielding or assist gas for plasma-cutting aluminium and stainless steel, and as an assist gas for laser-cutting stainless steel TIG-welding of tough-pitch copper
Heat-treatment processes to protect some of the most reactive metals.
In electrochemical analysis, can be bubbled through to displace any Oxygen.
Pressure-transfer, where the movement of liquids or slurries from one piece of process plant to another is effected using gas pressure.
Tyre inflation: helps to extend tyre life and prevent tyre bursts.
Pressurising accumulators for batch-testing applications.
Can be used for shrink-fitting: the intense cold of liquid Nitrogen (-196°C), reduces the physical dimensions of a component placed in the liquid. Once cooled, the component is connected to a mating component before swelling to its original size as it reaches room temperature, thereby securing itself in place

Helium

The primary source of Helium is from natural gas wells. It is obtained by a liquefaction and stripping operation. Due to the world shortage in Helium, many applications have recovery systems to reclaim the Helium. Helium is a highly specialized product. It’s chemically inert and non-flammable, with high thermal conductivity, low molecular weight and size, and the lowest boiling point known.

Application of Helium Gas In Industry

Helium is used to test critical automotive parts such as radiator heat exchangers, air conditioning components, fuel tanks and torque converters to ensure they meet quality specifications. It is also used in combination with Argon as a source of inflation in a growing number of airbags.

Electronics

Helium plays a significant role in the manufacturing of semiconductors, LCD panels and fibre optic wire. It cools parts and components quickly to enhance throughput, controls the rate of heat transfer to improve productivity and reduce defects and functions as a carrier gas in the production process.

Health Care

Helium is used to achieve cryogenic temperatures of -451 degrees required for superconducting magnets in MRIs and NMRs, allowing the capture of high-resolution images of internal organs and tissues. Cryogen & MRI Services

Hydrogen

Hydrogen is most frequently produced for on-site usage by steam reforming of natural gas. Such plants may also be used as sources of hydrogen for the merchant market. Other sources are the chlor-alkali processes that electrolysis sodium chloride solution to produce chlorine, and various waste gas recovery plants, such as at oil refineries or steel plants (coke oven gas). Hydrogen is also produced by electrolysis of water.

Application of Hydrogen In the Industries

An important addition to argon in a range of argon-hydrogen shielding gases for TIG and plasma welding.
Shielding gas mixtures are primarily used for welding austenitic stainless steels and some nickel alloys.
Can be used with argon in a range of gas mixtures for plasma-cutting primarily stainless steel and aluminium.
Used with oxygen for underwater flame-cutting. Deeper cutting requires increased pressure of fuel and oxygen.
Can be used as an alternative power source when used with a fuel cell to generate electricity.
In the glass industry, used to form the rim on glasses.

Oxygen

In commerce, liquid Oxygen is classified as an industrial gas and is widely used for industrial and medical purposes. Liquid Oxygen is obtained from the Oxygen found naturally in air by fractional distillation in a cryogenic air separation plant.

Application of Oxygen In the Industries

Widely used with a fuel gas for cutting, welding, brazing and soldering. The use of Oxygen gives higher flame temperatures than if air is used.
In oxy-cutting, an oxy-fuel flame preheats the steel to its ignition temperature. A jet of gaseous Oxygen flows onto the red-hot steel, generating more heat and melting the steel. The steel in contact with the Oxygen jet is oxidised, creating metallic slag which is blown from the cut, allowing more steel to react with the Oxygen.
In plasma and laser-cutting steel, an arc or laser beam is used to heat the steel to its ignition temperature. Oxygen is then used in the same way as with Oxygen-cutting to create an exothermic reaction and to blow away any metal oxide or slag.
Thermal lancing Oxygen is used in conjunction with the steel lance to create a high-temperature melting process capable of drilling or cutting through materials such as concrete, brick, stone and most metals.
High-purity Oxygen is used in the laboratories, process-control operations, metal analysis instruments and in semi-conductor production.
Used as an assist gas in lasers for cutting mild steel.

Carbon Dioxide

It is used in many consumer products that require pressurized gas because it is inexpensive and non-flammable, and because it undergoes a phase transition from gas to liquid at room temperature at an attainable pressure of approximately 60 bar, (870 psi, 59 atm), allowing far more Carbon Dioxide to fit in a given container than otherwise would.

Dissolve Actylene

Acetylene is manufactured commercially by reaction between Calcium Carbide and water, and as a by-product of ethylene production. Acetylene (C2H2) is a gaseous hydro- carbon with characteristics that make it highly suitable for technical applications. The gas contains 92.2 percentages by weight Carbon and 7.8 percent Hydrogen and is approximately 10 percent lighter than air. It has high calorific value due to the special chemical combination of Carbon and Hydrogen. When it is burned it releases large volumes of latent energy.

APPLICATIONS

Acetylene is the best and most versatile fuel gas for welding, straightening, bending, forming, hardening, cutting or tempering. It is the hottest flame temperature when compared to MAPP gas, propylene and propane and natural gas (2,910 ̊C, 2,895 ̊C, 2,800 ̊C and 2,780 ̊C respectively).
Acetylene is used as a fuel gas for oxy-acetylene welding, cutting, general localised heating, flame hardening, flame cleaning to remove rust from steel, spalling concrete and other processes requiring a high temperature flame (3,160 ̊C when combusted in Oxygen).
Specially purified instrument grade Acetylene which has such impurities (Arsine, Phosphine, Ammonia and Hydrogen Sulphide) removed is used in atomic absorption, analytical instrumentation and navigational beacons.
