Definition: “Butadiene” is the head of the C4 olefins family. Butadiene is a gas that condensates at -4.5°C. Mainly produced as byproducts from Ethylene by Ethane by steam cracking at high temperature (900°C), the Butadiene can also be obtained by Butane dehydrogenation or from Ethanol. Comments: Butadiene is mostly converted into Styrene Butadiene or Styrene Butadiene Rubber (SBR) more well known as synthetic Rubber  Polybutadiene is also used […]

Definition: “Ethylene” is one of the most important Olefin products. It is a colourless, flammable gas with a slightly sweet odor.  As shwon in the diagram below, it comes directly from the cracking in a steam cracker of different feedstocks: Gas such as ethane, propane, butane Liquid naphtha coming from oil refineries.  Comments: The chart below shows the […]

Definition: “Olefin” is the common name given by the “Petrochemical” industry  to the Alkene chemical products. The “Olefins” are classified in two families, the: “Monoolefins“, such as the “Ethylene” and “Propylene“ “Diolefins“, such as the “Butadiene” and the “Isoprene“ Comments: As we can see from the diagram above, the “Olefins” may be produced through a steam”Cracker” […]

Definition: A “cracker” breaks down large molecules from oil and natural gas into smaller ones. An ethylene “cracker” produces base petrochemical “building blocks” which are the first stage in the chemicals manufacturing chain. Comments: Natural gas companies have to remove Natural Gas Liquids (NGLs) from methane to make it “pipeline quality.” NGLs are made up of ethane, […]
