Petrochemical & Refined Products Services
This business segment includes the company’s propylene production facilities, which include propylene fractionation units and PDH facilities, and related pipelines and marketing activities; butane isomerization complex and related DIB operations; octane enhancement, iBDH and HPIB production facilities; refined products pipelines, terminals and related marketing activities; an ethylene export terminal and related operations; and marine transportation business.
Propylene Production Facilities and Related Operations
The company's propylene production facilities and related operations include propylene fractionation (or splitter) units, PDH facilities, propylene pipelines, propylene export assets and related petrochemical marketing activities.
Propylene Production and Related Marketing Activities: Propylene is a key feedstock used by the petrochemical industry. There are three grades of propylene: polymer grade propylene (PGP), with a minimum purity of 99.5%; chemical grade propylene (CGP), with a minimum purity of approximately 93-94%; and refinery grade propylene (RGP), with a purity of approximately 70%. Propylene fractionation units separate RGP, which is a mixture of propane and propylene, into either PGP or CGP. The company's PDH facilities produce 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.
To the extent it fractionates RGP for customers, the company enters into toll processing arrangements. In its petrochemical marketing activities, the company purchases RGP on the open market for fractionation at its splitter units and sell the resulting PGP to customers at market-based prices.
The company's petrochemical marketing activities also include the purchase of propane for its PDH facilities to process into PGP, which is then sold to customers under long-term sales contracts (take-or-pay arrangements) that feature minimum volume commitments and contractual pricing that minimizes its commodity price risk.
The company produces PGP at its Mont Belvieu area facilities and CGP at its BRPC facility. On a weighted-average basis, the overall utilization rate of its propylene production facilities was approximately 74.2% during the year ended December 31, 2024.
Propylene Pipelines: The results of operations from its petrochemical pipelines are primarily dependent upon the volume of products transported and the associated fees the company charges for such transportation services.
The maximum number of barrels per day that its petrochemical pipelines can transport depends on the operating rates achieved at a given point in time between various segments of each system (e.g., demand levels at each delivery point and the mix of products being transported). As a result, the company measures the utilization rates of its petrochemical pipelines in terms of net throughput, which is based on its ownership interest. Total net throughput volumes were 172 MBPD during the year ended December 31, 2024.
With the exception of the Lake Charles PGP Pipeline in Louisiana, the company operates all of its propylene production assets and related pipelines.
Propylene Export Assets: The company's EHT marine terminal located on the Houston Ship Channel includes export assets capable of loading up to 3,000 barrels per hour, or 72 MBPD, of semi-refrigerated propylene.

The high-purity isobutane feedstocks consumed in the production of these products are supplied by the company's isomerization units.
The company sells its octane enhancement products at market-based prices. It attempts to mitigate the price risk associated with these products by entering into commodity derivative instruments. To the extent that it produces MTBE, it is sold exclusively into the export market. The company measures the utilization of its octane enhancement facility in terms of its combined isooctane, isobutylene, and MTBE production volumes, which averaged 27 MBPD during the year ended December 31, 2024.
The company also owns and operates a facility located on the Houston Ship Channel that produces up to approximately 4 MBPD of HPIB and includes an associated storage facility with 0.6 MMBbls of related product storage capacity. The primary feedstock for this plant, an isobutane/isobutylene mix, is produced by the company's octane enhancement and iBDH facilities. HPIB is used in the production of polyisobutylene, which is utilized in the manufacture of lubricants and rubber. In general, the company sells HPIB at market-based prices with a cost-based floor. On a weighted-average basis, utilization rates for this facility were 90.4% for the year ended December 31, 2024.
Isobutane Dehydrogenation Unit: The company owns and operates an (iBDH) facility located in the Mont Belvieu area that is capable of processing approximately 25 MBPD of butane into nearly 1 billion pounds per year of isobutylene. Production from the iBDH plant enables the company to optimize its MTBE and high purity isobutylene assets and meet the growing market demand for isobutylene.
