Enterprise Products Operation LLC, Houston, has let an engineering, procurement, and construction contract for its planed propane dehydrogenation (PDH) unit at Mont Belvieu, Tex., to a subsidiary of Foster Wheeler AG’s Global Engineering & Construction Group. No contract value was disclosed.
Enterprise Products announced last year plans to build the 35,000-b/d PDH unit to take advantage of low-cost propane derived from increased NGL production out of nearby shale gas development.
At the time, the company did not specify the location but its siting the unit at Mont Belvieu complements the extensive fractionation the company operates there with several pipelines connected with local markets and export terminals.
The PDH unit will be able to produce as much as 750,000 tonnes/year of polymer-grade propylene, a prime feedstock for plastics manufacturers.
According to the 2012 announcement, the unit will be “one of the world’s largest.” Enterprise Products expects it to begin operating in third-quarter 2015 (OGJ Online, June 21, 2012).
