Propylene Methodology – 28 October 2013

Methodology

Propylene is a colourless, highly flammable gas. It is produced by several routes, the most common of which is as a co-product of ethylene production from steam crackers. Propylene is also produced through fluid catalytic cracking (FCC) of feedstock, usually vacuum gas oil for gasoline production. This is the major source of supply in the US. Output from FCCs is not of […]
