U.S. ethane consumption, exports to boost as new petrochemical plants come online

Over a subsequent dual years, EIA’s Short-Term Energy Outlook (STEO) projects growth in U.S. expenditure of ethane in a petrochemical attention will surpass increases in expenditure of all other petroleum and glass products—such as engine gasoline, distillate, and jet fuel—combined. EIA also projects that ethane exports will continue increasing, as ethane is exported both by pipeline to Canada and by tankers to some-more apart destinations.

Ethane is distant from tender healthy gas during healthy gas estimate plants along with other hydrocarbon gas liquids(HGL) such as propane, normal butane, isobutane, and healthy gasoline. Ethane is especially used as a petrochemical feedstock for a prolongation of ethylene, that is a building retard for plastics, resins, and other industrial products.

As U.S. healthy gas prolongation has increased, a volume of ethane contained in tender healthy gas prolongation streams has exceeded domestic direct or a ability to trade it abroad. This conditions has led producers to leave some of a ethane in a healthy gas stream, adult to acceptable boundary set by healthy gas pipelines and placement systems, and to sell it as healthy gas, rather than redeem and marketplace ethane as a apart product.

Nonetheless, ethane is increasingly being recovered from a healthy gas stream, and U.S. ethane expenditure is augmenting as existing ethylene crackers have stretched and new plants have begun operating. In addition, expanding tube networks and dual new ethane trade terminals have authorised U.S. ethane exports to increase.

In 2017, construction was finished on a initial 3 of a array of new ethylene crackers—two early in a year and a third in late December, all on a Texas Gulf Coast. These crackers stretched a ability to devour ethane in a United States by 210,000 barrels per day (b/d), and EIA expects ethylene plant ability to continue to expand: 6 ethylene crackers, collectively able of immoderate 380,000 b/d of ethane, are designed to be finished by a finish of 2019. EIA expects annual U.S. ethane expenditure to grow from an estimated 1.2 million b/d in 2017 to 1.4 million b/d in 2018 and 1.6 million b/d in 2019 as these new plants and associated infrastructure ramp adult operations.

EIA also projects continued expansion in ethane exports, with normal annual exports augmenting from 180,000 b/d in 2017 to 290,000 b/d in 2018 and 310,000 b/d in 2019. Ethane exports by tube to Canada are approaching to boost in early 2018 as shipments on a Utopia tube that crosses a U.S.-Canada limit nearby Detroit start to upsurge and as an ethylene plant in Sarnia, Ontario, expands capacity.

Ethane is also exported by tanker from terminals during Marcus Hook, Pennsylvania, and Morgan’s Point, Texas, that both non-stop in 2016. Ethane shipments from these comforts now supply petrochemical feedstock to countries including a United Kingdom, Norway, Sweden, India, and Brazil. By a finish of 2019, ethane exports from a United States might also strech China when a new ethylene plant there starts operation.
