August U.S. Ethane Exports up From July

Taken together, the ethane-related infrastructure projects developed in the U.S. over the past several years serve as a reliable feedstock-delivery network for a number of steam crackers in Europe, Asia, and Latin America. NGL pipelines transport y-grade to fractionation hubs, fractionators split the mixed NGLs into ethane and other “purity” products, ethane pipelines move the feedstock to export terminals fitted with the special storage and loading facilities that ethane requires, and a class of cryogenic ships — Very Large Ethane Carriers, or VLECs — sails ethane to mostly long-term customers in distant lands. The end results of all this development are virtual ethane pipelines between, say, the Marcellus/Utica and Scotland, or the Permian and India. Today, we continue our series on ethane exports with a look at the two existing export terminals, the ethane volumes they have been handling, and where all that ethane has been headed.

The run-up in U.S. production of natural gas liquids over the past 10 years spurred the development of a whole lot of infrastructure. More pipelines to transport mixed NGLs from production areas to NGL storage and fractionation hubs, especially Mont Belvieu, TX. More fractionators to split y-grade into ethane, propane, and other “purity” products. And, specifically for ethane — the lightest, quirkiest, and most plentiful NGL — a number of ethane-only steam crackers were built along the Gulf Coast to take advantage of the new supply abundance, as were ethane-only pipelines, export terminals, and a whole new class of cryogenic ships — Very Large Ethane Carriers, or VLECs — to move the product to markets in Europe and Asia. Today, we begin a new series on the unique nature of overseas ethane exports, including why most incremental export volumes are tied to long-term supply deals with a handful of global ethylene plants designed — or reconfigured — to “crack” ethane.
