Series of Enterprise projects has propane implications

Enterprise Products Partners LP is undertaking several projects to convert and expand segments of its petrochemicals pipeline network.

One project involves the 149-mile North Dean pipeline, which will be converted from refinery grade propylene (RGP) service to polymer grade propylene (PGP) service. According to a press release, RGP is a mixture of propane and propylene that is fractionated into PGP. PGP is used as a feedstock in the production of various consumer products, including packaging film, fibers for carpets and upholstery, and molded plastics parts for appliances and automotive, houseware and medical products.

Enterprise says the North Dean pipeline conversion should be completed by January 2017. It will originate at Enterprise’s complex in Mont Belvieu, Texas, and serve petrochemical facilities as far south as Seadrift, Texas. Construction of a 33-mile lateral pipeline, new metering stations and additional pumping capacity will increase Enterprise’s total PGP delivery capacity to more than 150,000 barrels per day.

In addition, Enterprise is converting the Lou-Tex propylene pipeline, which is a 263-mile, bi-directional pipeline that currently transports chemical grade propylene (CGP) between Sorrento, La., and Mont Belvieu. The pipeline will be converted to PGP service, and the conversion is scheduled for completion in 2020.

Enterprise also plans to construct a 65-mile, 10-inch-diameter pipeline that will transport RGP between Sorrento, La., and Breaux Bridge, La. The pipeline is scheduled for completion in early 2017. Rail receipt facilities at Mont Belvieu are also being expanded to give Enterprise the capability to unload up to 100 RGP railcars per day, the company says.

According to Enterprise, its PGP infrastructure at Mont Belvieu currently consists of six propane/propylene fractionators.
