Chemicals: Ethylene is the starting material for several industrial syntheses. It is employed as an intermediate in the chemical industry and for the production of plastics.
Food & Beverages: An ethylene/nitrogen mixture supplied in cylinders is used to control ripening of fruit, especially bananas. A concentration of a few ppm in the warehouse atmosphere is used. It is also used in agriculture to promote crop growth. In this application the gas is directly injected into the soil.
Glass: Ethylene is used in the production of specialty glass for the automotive industry (car glass).
Medical: Ethylene is used as an anaesthetic.
Metal Fabrication: Ethylene is used as oxy-fuel gas in metal cutting, welding and high velocity thermal spraying.
Refining: Ethylene is used as refrigerant, especially in LNG liquefaction plants.
Rubber & Plastics: Ethylene is used in the extraction of rubber.
