Oh Propylene – Why Can’t You be True? On-Purpose Propylene via Propane Dehydrogenation (PDH)
Up until a few years ago, propylene production was mostly a derivative of the petroleum refining and olefin cracking industries. But that is changing big time. Nowadays propylene demand in Asia is booming, US propane supplies are abundant and propylene output from refineries and olefin crackers is declining. Time to get serious about making propylene on purpose! As a result three new propane dehydrogenation (PDH) plants are expected online at the US Gulf Coast in 2015 and 2016 that will produce 4.3 billion pounds/year. These plants will help close the gap between increasing world propylene demand and declining “by-product” production from olefin crackers and refineries. They will also help soak up growing US propane supplies. Today we examine the recent rapid growth in PDH plant projects.
