Propane dehydrogenation displacing by-product propylene supply
On-purpose propylene now covers roughly 38% of global supply, up from a small fraction two decades ago, because ethane crackers and closing refineries no longer produce it in the quantities polymer demand requires. That shift moves the industry's cost structure from a by-product basis to a dedicated one, with all the return requirements a standalone plant carries. Chinese producers built most of the new capacity. Utilisation near 71% shows how far the build ran ahead of the spread economics needed to support it properly. The polymer industry inherited a cost structure it did not choose.
