The EnLink Midstream companies have completed a natural-gas liquids project that includes a 100,000-barrel-per-day fractionator next to the companies’ Plaquemine natural gas processing plant.

The natural gas processing expansion is part of the just-completed second phase of the Cajun-Sibon natural gas liquids project. The project also included adding 50,000 barrels per day of capacity to the Cajun-Sibon pipeline, which connects supply pipelines in east Texas to EnLink Midstream’s gas processing facility in Eunice and 90 miles of natural gas liquids pipeline connecting the Eunice and Plaquemine facilities.

Gas processing plants, or fractionators, collect the natural gas produced in area and separate it into different components: methane gas, liquefied ethane and heavier hydrocarbons.

EnLink Midstream is based in Dallas. The company’s assets include roughly 7,400 miles of gathering and transportation pipelines, 13 processing plants capable of processing 3.4 billion cubic feet per day of natural gas; seven seven fractionators with a daily capacity of 252,000 barrels per day; as well as barge and rail terminals, product storage facilities, brine disposal wells, an extensive crude oil trucking fleet and equity investments in certain private midstream companies.

Earlier this year, EnLink announced a partnership with a Marathon Petroleum Corp. that will build a 30-mile natural gas liquids pipeline connecting EnLink’s Riverside processing and terminal complex in Geismar to Marathon’s Garyville refinery. The project is expected to be completed during the first half of 2017.
