Propylene: Relationships

Every element and industry that Propylene is linked to, and how. Each pair has its own card explaining the relationships between the two.

• Polypropylene: About two-thirds of the world's propylene is made into polypropylene, so PP margins are a spread over propylene, and the route that supplies the propylene (cracker, refinery or propane dehydrogenation) sets the cost floor. (researched)
• Crude oil: Most propylene is a by-product of cracking crude-derived naphtha and of refinery catalytic crackers, so oil sets its cost, but propane dehydrogenation is a growing route that loosens the link. (researched)
• Ethylene: Ethylene and propylene come out of the same steam cracker, in proportions fixed largely by the feed: ethane gives almost no propylene, naphtha gives about half as much propylene as ethylene. The move of US crackers to cheap ethane cut co-product propylene, and dedicated routes such as propane dehydrogenation grew to fill the gap. (researched)
