Summary Information

The Project

  • Project Type: Expansion of existing Refinery
  • Project Summary: Expanding the Port Arthur Refinery, a project that will increase its capacity from 275,000 to more than 600,000 barrels a day
  • Main Contractors:
    • A joint venture of Jacobs Engineering Group Inc. and Bechtel Corporation will manage the engineering, procurement, and construction for the facility expansion
    • Teton Industrial Construction, Inc., an independent operating company in the PCL family of companies, has been awarded the $130-million dollar OSBL (outside the battery limit) GC (general contractor)—1 & 2 Packages
    • KBR has been selected to construct the petroleum coker (pet coke) material handling system
    • Dragados Offshore: Assembly of OSBL Piperack Modules

Refining Units

  • For this project, Motiva has designed one of the largest single-train crude distillation units in the world, capable of processing 325,000 barrels daily.
  • Catalytic reformer: Converts about 85,000 barrels per day into high-octane gasoline for blending.
  • Isomerization unit: Produces gasoline blend components without creating benzene.
  • Hydrotreater: Prepares the feed by removing sulfur.
  • Other fractions from the crude distillation unit will go into the new hydrocracker, one of the largest in the world, which will upgrade about 75,000 barrels per day into gasoline and diesel. “This hydrocracker will be integrated with a new 60,000-barrel-per-day diesel hydrotreater, which makes it unique,” Burt says. “Typically, the units are separate, but we’ve chosen to integrate them to take advantage of their many common functions, which provides a cost advantage.”
  • A new 50,000-barrel-per-day-capacity cat feed hydrotreater, also being designed by Motiva, will pre-treat feedstock for the refinery’s existing catalytic cracker
  • With a capacity of 95,000 barrels per day, the coker is more than 50-percent larger than the refinery’s existing coker.

Terminal Capacity

  • Crude Oil:
  • Refined Products:

Crude Supply

  • Saudi Arabia will be the sole supplier of crude oil when the project is completed
  • The expanded refinery can process a wide variety of crude oils, ranging from relatively light to heavy

Products Produced

  • The refinery has a very high white product yield and has flexibility to switch between primarily producing gasoline and diesel to adapt to varying market conditions


  • 2007 - Shell announces final investment decision
  • 2007 - Jacobs Engineering received authorization to proceed with detail design and construction
  • 2007 - Ground breaking ceremony held
