LPG exports out of Gulf Coast marine terminals averaged 1 MMb/d in 2018, a gain of 12% from 2017 and 35% from 2016. And, with U.S. NGL production rising steadily, 2019 is looking to be another banner year for LPG shipments to overseas buyers. The increasing volume of propane and normal butane — the NGL purity products generally referenced as LPG — is filling up the existing export capacity of the Gulf Coast’s six LPG terminals and spurring the development of a number of expansion projects. Today, we continue our blog series on propane and butane export facilities along the Gulf, West and East coasts, and what’s driving the build-out of these assets.
As we said in Part 1, the U.S. flipped from being a net LPG importer to a net exporter seven years ago, in 2012. Since then, exports by ship have skyrocketed to more than 1.1 MMb/d in 2018, with the vast majority of that volume (about 92%, as of year-end 2018) being sent out of the half-dozen LPG terminals in coastal Texas and Louisiana. The rest of the exports-by-ship are flowing through either the Ferndale terminal in Washington State (red dot and lettering in Figure 1), the Marcus Hook facility near Philadelphia (green dot and lettering) or DCP Midstream’s Chesapeake terminal in Virginia (light blue dot and lettering). In the initial blog in this series, we also noted that the bulk of U.S. LPG exports have been bound for Asia and Latin America, with smaller but still-significant volumes sent to Europe, Africa and the Caribbean. We concluded Part 1 with a review of the Gulf Coast’s — and the U.S.’s — largest LPG export facility: the Enterprise Hydrocarbon Terminal (EHT; dark blue dot and lettering) on the Houston Ship Channel, whose capacity is in the midst of being expanded to 720 Mb/d from the current 545 Mb/d. EHT, which can also handle a number of other energy commodities, is connected by several pipelines to Enterprise Products Partners’ NGL fractionation and storage complex at Mont Belvieu; Enterprise owns all or part of nine existing fractionators (combined capacity, 755 Mb/d) at the hub and is building 300 Mb/d of additional fractionation capacity there that will come online in the first half of 2020.
