Liquid Ethylene (R1150)
Introduction:
Ethylene (IUPAC name: Ethene) is a hydrocarbon with the formula C2H4 or H2C=CH2. It is a colorless flammable gas with a faint "sweet and musky" odor when pure. It is the simplest alkene (a hydrocarbon with carbon-carbon double bonds), and the second simplest unsaturated hydrocarbon after acetylene (C2H2). Ethylene is widely used in chemical industry, and its worldwide production exceeds that of any other organic compound.
Ethylene (R1150) is supplied as a compressed liquid in cylinders and ISO tube skids and as a cryogenic liquid in T75 cryogenic iso containers for international transport. It is generally used in very low temperature industrial refrigeration applications such as LNG liquefaction processes.
Ethylene is used in a range of industries and applications including:
◆ 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.
