Acetylene
Acetylene is traditionally generated through a chemical process using Calcium-carbide and water.
Beside this acetylene is increasingly produced as by-product in the petrochemical industry.
Acetylene is the only fuel gas to cover all industrial oxy-fuel application due to its high performance and other physical properties.
Because of its reactivity acetylene cannot be stored and distributed in hollow gas-cylinders like other gases. Acetylene cylinders are filled with a porous mass, which contains Acetone in its pores. The acetylene molecules are dissolved in the acetone and escape when the cylinder-valve is opened.
In Malaysia only available from Linde: Cylinder bundles with 95kg Acetylene contents.
Modern Acetylene production plants assure safety, quality and reliability.

Oxygen
Oxygen is component of air at about 21%. Like Nitrogen and Argon, Oxygen is mainly recovered by separation of cryogenic liquified air. This procedure, which was invented by Carl von Linde more than 100 years ago, uses the different densities of liquified air components.
Oxygen is supplied as compressed gas in both single cylinders or cylinder-bundles, or liquified for tank-usage.
Nitrogen
With 78% Nitrogen is the other main component of air beside Oxygen.
Depending on the application purities vary between 99,5% (industrial grade 2.5) and 99,999999% (ultrahigh purity 8.0) Nitrogen is supplied as compressed gas in both single cylinders or cylinder-bundles, or liquified for tank-usage.
Argon
Argon is the third industrially harvested component of air. Since the concentration of Argon in air is only approximately 1%, it took much longer to introduce Argon to the industry than Oxygen and Nitrogen.
Hydrogen
Hydrogen may be obtained by means of a steam-reformer from steam, natural gas or other light hydrocarbons. Refineries and electrolytic processes employed in chlorine chemistry also generate hydrogen-rich gases from which the hydrogen can be recovered.
Liquid hydrogen
Liquid hydrogen is manufactured in our Ingolstadt plant, Germany's sole industrial plant for hydrogen liquifaction. The hydrogen is liquified at -253°C and is transported in its liquid state, reducing transport costs.
Gas mixtures
Industrial gas mixtures are developed to optimize gas applications like welding, metallurgy and food-processing.
One of the most famous Linde gas mixtures is Corgon®, a welding shielding-gas based on Argon and CO2 . Compared to the traditional CO2 , MIG-welding with Corgon® achieves much higher welding performance without sputter.
Helium
Helium is recovered most cost-effectively from natural gas. Long-term contracts guarantee access to sources in the USA, Europe and North Africa.
Carbon dioxide
Linde Carbon dioxide is generated in the chemical industry and purified to the quality required for the food-processing sector.
Food grade liquid CO2 is used extensively in the beverage industry to carbonate “soft – drinks”. It may also be used from time to time in the manufacture of beer, wine and champagne.
Foods in packages can be kept fresh by creating a CO2 atmosphere in the package. This also can prolong the products’ shelf life and preserves the taste.
Food processing involving meat requires that temperatures during the process be kept low to avoid bacterial activity and smearing of fat when cutting, milling or forming. Liquid CO2 injection (Dry Ice depositing) will provide fast production at low temperatures.
The manufacturing industry uses CO2 for Metal Inert Gas (MIG) welding to provide shielding from oxygen and moisture allowing for quality welds.
The steel casting industry (foundries) improve efficiency by using CO2 to set the casting moulds quickly.
The firefighting industry uses C02 extensively in fire extinguishers. CO2 has the added advantage over water as it will not cause electrical short-circuits and leaves no residual mess.
Plants can achieve higher growth rates on exposure to small concentrations of C02. Glasshouses used for commercial production often use this technology to improve the growth or yield of the plant.
In the agricultural industry a C02 atmosphere can kill vermin. The CO2 quickly dissipates and there are no lingering health risks. Using this method eliminates the need to use expensive and unhealthy chemicals.
The CO2 treatment of water for drinking or for industrial applications is well known and practiced in the region. It allows for the adjustment of PH without or with reduced use of chemicals.
Beside supplying CO2 cylinders up to 33kg capacity, Linde offers CO2 bundles for 'power-users', e.g. casting industry or centralized gas supply users.
Dry Ice
Dry Ice or solid Carbon Dioxide is widely used in Malaysia and Singapore. As it maintains a temperature of –78 degrees C it is primarily used for its superior cooling ability.
The catering industry (airlines) use Dry Ice to keep food and drink cold on flights. They use slabs of Dry Ice in their in-flight trolleys where the food is kept preserved for long flights.
Dry Ice blasting with pellets is gaining popularity as it can clean difficult and stubborn deposits without the use of chemicals, sand or water. This is particularly useful in areas with electrical connections, smearing or elastic contamination or in-house cleaning applications with the need of quick re-commissioning.
Typical Dry Ice supply forms are pellets with 3 or 9mm diameter,
slabs
and blocks.
To reduce evaporation losses, Dry Ice should be transported in specialized insulated containers.
Those containers are available for rent in Malaysia only from Linde.
