frac trains

There’s never a dull moment in the ethane market. Four new steam crackers and an expansion at an existing plant are slated to begin operating along the Gulf Coast in 2019, and a recently restarted Louisiana cracker will continue to ramp up to full capacity — together adding about 250 Mb/d of ethane demand by year’s end. You’d think there would be plenty of ethane out there for them. After all, U.S. NGL production has been on the rise, driven in part by new Permian gas processing plants and new NGL pipeline capacity to the coast. But fractionation constraints at the Mont Belvieu hub are likely to linger through 2019, raising questions about how much ethane will actually be produced and how much will need to be rejected into pipeline gas. Today, we consider the challenges facing the ethane market this year as demand increases and fracs run flat out to keep pace.

Fractionators at the Mont Belvieu hub operated at or near full capacity through the second half of 2018 as they struggled to deal with a deluge of mixed NGLs from the Permian and other key production areas. This situation — barely enough capacity to keep pace with rising demand for fractionation services — is likely to continue through 2019, even as a number of new fractionators come online. But NGL producers and the midstream sector are on the case: a slew of additional frac capacity has been announced since last fall, all of it slated to begin operation in 2020 or early 2021, and all of it backed by long-term contracts. Today, we discuss ongoing efforts to make the most of existing frac trains and to add new capacity pronto.
