The facility can extract about 37,000 barrels per day of natural gas liquids (NGLs).
Existing Eagle Ford production will be processed by the plant in a reduced recovery mode during the start-up period, to enable testing of the plant and supporting facilities.
Enterprise general partner executive vice president and chief operating officer Jim Teague said, "The coordination, hard work and dedication exhibited by our employees in Houston and in the field has been tremendous and allowed us to complete this first train on schedule and under budget."
The company said a 65-mile, 36-inch diameter residue natural gas pipeline linking the plant to Enterprise’s Wilson natural gas storage facility was completed last month.
Construction of 169 miles of 20-inch and 24-inch diameter pipeline for delivering mixed NGLs extracted at Yoakum to Enterprise’s fractionation and storage complex at Mont Belvieu, Texas, was also completed by the partnership.
