The recent startup of Chevron Phillips Chemical Co. LP’s facility in Baytown, Texas, is turning out to be what it was cracker-ed up to be.

Fresh demand sent ethane prices up 3.2% at the Mont Belvieu, Texas, hub last week to its highest point since the end of January, and 20.3% at Conway, Kan. The Mont Belvieu margin improved from 5.6 cents per gallon (gal) to almost 7 cents/gal.

At peak, the energy-efficient Cedar Bayou cracker will boast a capacity of 1.5 million metric tons of ethylene per year. The new cracker will feed its two sister polyethylene units in Old Ocean, Texas, which launched in September 2017. The new plants jump-start what Chevron Phillips calls its “new era of growth” for its petrochemical business on the Gulf Coast.

“The U.S. Gulf Coast petrochemicals project is the most transformational project in the history of our company,” said Mark Lashier, president and CEO of Chevron Phillips Chemical, in a statement on March 12.

En*Vantage Inc. expects rising ethane demand as other crackers pick up, among them:

  • Singapore-based Indorama Corp.’s Lake Charles, La., ethane/propane cracker, with capacity of 370,000 tons per year was expected to start up soon; and
  • DowDuPont’s light hydrocarbon 9 plant in Freeport, Texas, down for maintenance at the beginning of the month, is back online.

That means that ethane inventories should be trending downward as demand rises by 200,000 barrels per day between March and September, En*Vantage projects. The analysts forecast the price, which Hart Energy gauges at just under 25 cents/gal at Mont Belvieu this past week, to average around 30 cents/gal at mid-year and 35 cents/gal by the end of 2018.

The price of propane was up 5.7% at Mont Belvieu to return to the 80 cents/gal range and rose for the first time in a month to about 66 cents/gal at Conway. Margins also widened by about 10% at Mont Belvieu and 12% at Conway.

In the week ended March 16, storage of natural gas in the Lower 48 experienced a decrease of 86 billion cubic feet (Bcf), the U.S. Energy Information Administration reported, close to the Bloomberg consensus of an 89 Bcf draw and more than the five-year average of 53 Bcf. The figure resulted in a total of 1.446 trillion cubic feet (Tcf). That is 31.6% below the 2.113 Tcf figure at the same time in 2017 and 18.5% below the five-year average of 1.775 Tcf.
