Enterprise Products Partners LP said Sept. 2 that construction of the Texas-to-Louisiana segment of the Aegis Pipeline is complete and ready to deliver ethane to additional Gulf Coast petrochemical facilities. The segment runs from Beaumont, Texas to Lake Charles, La.

The segment is 48 miles long, and the initial 60-mile segment is currently in service. The final leg of Aegis, which totals 270 miles, will extend the pipeline from Lake Charles to the Mississippi River and is expected to be completed by the end of 2015.

Combined with Enterprise’s existing South Texas system, Aegis will provide shippers access to a 500-mile ethane header system between Corpus Christi, Texas, and the Mississippi River in Louisiana.

Customer commitments support more than 300,000 barrels per day (Mbbl/d). The capacity can expand to about 400Mbbl/d with additional pumps.

A.J. (Jim) Teague, COO of Enterprise’s general partner, said Aegis’ route will serve about 20 petrochemical facilities representing more than 90% of the nation’s ethylene capacity by 2020.

Enterprise’s Mont Belvieu complex is the end point for more than 3MMbbl/d of NGL supply pipeline capacity. It is connected to more than 2MMbbl/d of industry NGL fractionation capacity and more than 110MMbbl salt dome storage capacity, owned by Enterprise.

Houston-based Enterprise Products Partners LP is a domestic-focused midstream company.
