Ethylene
Our ethylene system serves as an open market storage and trading hub for the ethylene industry by incorporating storage capacity, connections to multiple ethylene pipelines, and high-volume export capabilities. In support of our ethylene business, our Chambers County, Texas storage complex includes a high-capacity underground ethylene storage well. The storage well is connected to our Morgan’s Point ethylene export terminal and ethylene pipelines.
The ethylene export terminal features two docks and a nameplate capacity to load 1 million tons of ethylene per year. Ethylene is the primary feedstock for a wide variety of consumer products, including cell phones and computer parts, food packaging, apparel, textiles and personal protective equipment. We own a 50% member interest in Enterprise Navigator Ethylene Terminal LLC, which owns the export facility.

Propylene
Our propylene production facilities and related operations include propylene fractionation (or splitter) units, a PDH facility, propylene pipelines, propylene export assets and related petrochemical marketing activities.
Propylene is a key feedstock used by the petrochemical industry. There are three grades of propylene: polymer grade propylene (“PGP”), chemical grade propylene (“CGP”), and refinery grade propylene (“RGP”). Propylene fractionation units separate RGP, which is a mixture of propane and propylene, into either PGP or CGP. Our PDH facility produces PGP using propane feedstocks. The demand for PGP primarily relates to the manufacture of polypropylene, which has a variety of end uses including packaging film, fiber for carpets and upholstery, molded plastic parts for appliances, and automotive, houseware and medical products. CGP is a basic petrochemical used in the manufacturing of plastics, synthetic fibers and foams. Our EHT marine terminal located on the Houston Ship Channel includes export assets capable of loading propylene.

Butane Isomerization
Isomerization units convert normal butane feedstock into mixed butane, which is a stream of isobutane and normal butane. DIB units, of which we own and operate ten located at our Chambers County, Texas complex, then separate the isobutane from the normal butane. Any remaining unconverted (or residual) normal butane generated by the DIB process is then recirculated through the isomerization process until it has been converted into varying grades of isobutane, including high-purity isobutane. We own and operate three isomerization units located in Chambers County, Texas that comprise the largest commercial isomerization facility in the U.S. We also own and operate a high-purity isobutane pipeline system.

Octane Enhancement
Enterprise owns and operates an octane enhancement production facility located in Mont Belvieu, Texas that is designed to produce products that are used by refiners to increase octane values in reformulated motor gasoline blends. The high-purity isobutane feedstocks consumed in the production of these products are supplied by our isomerization units.

Refined Products
Our refined products services business includes refined products pipelines, terminals and associated marketing activities. We own and operate regulated interstate and unregulated intrastate Texas refined products pipelines. Our refined products pipelines transport a variety of products including motor gasoline and distillates. We also operate storage terminals, truck terminals and marine terminals handling refined products.

Marine Services
Our marine transportation business consists of tow boats and tank barges used to transport refined products, crude oil, asphalt, condensate, heavy fuel oil, LPG and other petroleum products on key U.S. inland and intracoastal waterway systems. The marine transportation industry uses tow boats as power sources and tank barges for freight capacity. Our marine transportation assets serve refinery and storage terminal customers along the Mississippi River, the intracoastal waterway between Texas and Florida, and the Tennessee-Tombigbee waterway system.
