Liquefied petroleum gases emergencies

Port Arthur Steam Cracker, Texas (USA) 2013 The Port Arthur steam cracker is one of the biggest in the world, with a capacity of 1 Mtpa of ethylene. The project was commissioned in 2001 to process naphtha distiled from petroleum. In response to petroleum product price hike and the emergence of abimdant gas resources, they adapted the steam cracker to give it flexibility and maintain its competitiveness. It can now use as a feedstock ethane, which costs around 30 per barrel of oil equivalent (boe) versus around 100/boe for naphtha and liquefied petroleum gases such as butane and propane, which are also cheaper.
