Definition - What does Olefin mean?
An olefin refers to an alkene chemical compound that is comprised of hydrogen and carbon, with one or more pairs of the carbon atoms connected by a double or triple bond. They are unsaturated hydrocarbons that cause heavy corrosion in the processing plants used to produce them.
Corrosionpedia explains Olefin
Olefins are hydrocarbons that have one or more double or triple bonds between carbon atoms in their linear chain. An example of an olefin is ethylene (C2H4), which is the smallest olefin.
Olefin processing plants are a component of a full crude oil stream from which a wide range of valuable products are extracted. However, these plants are prone to corrosion because the equipment and piping are largely composed of carbon steel. A method to reduce corrosion in this industrial environment is to inject ethylene diamine into at least one stream of the plant.
