Ethane had a pretty good week, even if its sister NGL struggled.

The Mont Belvieu, Texas, price rose above 26 cents per gallon (gal) for the first time since late January and the margin widened by almost 5% last week to 8.55 cents/gal.

The January spike in ethane was tied to the blast of cold weather that drove natural gas prices skyward, En*Vantage said. Unlike that rise, the increase in ethane prices now is driven by demand, specifically new ethane crackers like Chevron Phillips Chemical Co. LP’s new Cedar Bayou facility in Baytown, Texas, and increased exports from Morgan’s Point on the Houston Ship Channel.
