Lone Star NGL LLC, a subsidiary of Energy Transfer Partners LP (ETP) said May 4 that it will construct a fourth NGL fractionation facility at Mont Belvieu, Texas.

The facility, Fractionator IV, will cost about $450 million. It is scheduled to be operational by December 2016.

Fractionator IV can handle 120,000 barrels per day (Mbbl/d). It has several long-term contracts, and it will provide off-take for Lone Star Express Pipeline, a new 533-mile, 24- and 30-inch pipeline.

Lone Star Express will take about 475 Mbbl/d of NGL from the Delaware Basin to Mont Belvieu, Texas. The capacity can be expanded to 705 Mbbl/d, ETP added.

Phase I and phase II of the pipeline are scheduled to be completed in second-quarter 2016 and fourth-quarter 2016.

ETP also said that Lone Star’s third Mont Belvieu fractionation facility, also currently under construction, will be completed in January 2016.

Dallas-based Energy Transfer Partners LP is a domestic-focused midstream MLP.
