NGL Fractionation
NGL fractionation facilities separate mixed NGL streams into discrete NGL products: ethane, propane, normal butane, isobutane and natural gasoline. The three primary sources of mixed NGLs fractionated in the United States are domestic natural gas processing plants, domestic crude oil refineries and imports of butane and propane mixtures. The mixed NGLs delivered from domestic natural gas processing plants and crude oil refineries to our NGL fractionation facilities are typically transported by NGL pipelines and, to a lesser extent, by railcar and truck.
Enterprise owns interests in 8 NGL fractionators with a combined net fractionation capacity of 519 MBPD. These facilities are located on the Texas and Louisiana Gulf Coast and are linked by pipelines to some of the largest consumers of NGLs in the United States and to international markets through the partnership's import/export terminal on the Houston Ship Channel. Generally, the partnership receives a fee on the volume of NGLs fractionated.
Our Mont Belvieu NGL fractionator is one of the largest NGL fractionation facilities in the United States with a gross capacity of 230 MBPD and a net capacity of 178 MBPD. This facility fractionates mixed NGLs from several major NGL supply basins in North America including the Mid-Continent, Permian, San Juan, Rocky Mountain Overthrust, East Texas and the U.S. Gulf Coast. We own 75% of this facility.
The partnership's Norco NGL fractionator, located near New Orleans, Louisiana, has a gross capacity of 75 MBPD. This facility receives mixed NGLs via pipeline from refineries and natural gas processing plants. At this facility, Enterprise is compensated for fractionation services under percent-of-liquids, or in-kind fees, contracts and fee-based contracts.
Promix owns a fractionator located in Napoleonville, Louisiana, which has the capacity to fractionate up to 145 MBPD of mixed NGLs from natural gas processing plants on the Louisiana, Mississippi and Alabama Gulf Coast. Enterprise and an affiliate of Dow Chemical Company each own a 50% interest in this facility. The Promix and Norco fractionators are the hubs of our NGL value chain in Louisiana, where we expect to see a substantial increase in NGL volumes flowing from the start up of new developments in the Gulf of Mexico including those in the prolific Southern Green Canyon area.
The Hobbs NGL fractionation facility is located in Gaines County, Texas, where it serves petrochemical end users and refineries in West Texas, New Mexico and California. In addition, the Hobbs facility can supply exports to northern Mexico through existing pipeline infrastructure. The Hobbs facility receives mixed NGLs from several major supply basins including Mid-Continent, Permian Basin, San Juan Basin and the Rocky Mountain Overthrust. The facility is strategically located at the interconnect of our Mid-America Pipeline System and Seminole Pipeline, providing us flexibility to supply the nation's largest NGL hub at Mont Belvieu, Texas as well as access to the second-largest NGL hub at Conway, Kansas.
