5.4 Chemicals
Air Liquide supplies Chemicals (Methane, Ethane, Ethylene, Propane, Propylene, Ammonia etc) in various packaging ranging from 10 L sized cylinders to 110 L Drum and pallets. They are available in a few grades for different applications.
Ammonia (NH3)
Ammonia has its application in various industrial fields such as chemical, petroleum, wood and metal. It is one of the oldest refrigerant gases used in industries such as ice making, freeze drying and process cooling.
Other examples of applications are:
- Fertilisation of soil.
- Additive to prevent coagulation of raw latex during storage in rubber industries.
- Cleaning agent.
Sulfur Hexafluoride (SF6)
In semiconductor and display manufacturing, Sulfur Hexafluoride provides fluorine source for high density plasma etching without generating carbon by-products. Sulfur Hexafluoride can be used for etching Metal Silicides, Nitrides and Oxides versus their metal substrates. It is also used in display fabrication for the cleaning of the Chemical Vapour Deposition (CVD) reactors.
Sulfur Hexafluoride is also used as a dielectric (insulating material) in electrical transformers.
Air Liquide is able to provide alternatives for SF6 replacement to reduce Greenhouse Gases.
Fumigas
Our Fumigas products consist of the Ethylene Oxide (EtO / EO) and Carbon Dioxide (CO2) mixtures for the fumigation and sterilisation process of packaging and food products.
Methane (CH4)
A major constituent of Liquefied Natural Gas (LNG), Methane is a fuel gas used in various industries where it offers clean burning. Higher purity Methane is used in the production of carbon black, a material used in electronic components.
Methane is also used in the testing of the gas appliances in natural gas areas.
Propane (C3H8)
As a Liquefied Petroleum Gas (LPG), Propane is used as a fuel gas in industries where to provide cleaner combustion than fossil fuels.
Other applications include metal melting in the metal work industries, refrigerant use for several industries and thermo bulb fill for temperature and pressure control instruments.
Sulfur Dioxide (SO2)
Sulfur Dioxide is used as an additive to etch gas mixtures in electronic industries or a preservative for beer, wine and meats in food and beverage industries. It can also be used as a refrigerant, or sterilisation as well.
