Mobile refinery
Also known as:
Shell Saraland, Vertex Mobile, Alabama Refining, Alabama Renewables
Saraland is a small, simple refinery located on the north side of Mobile, Alabama in the southeast US.
Saraland is owned and operated by Vertex after acquiring the plant in 2022 from Shell.
Saraland originally produced hydrotreated heavy gas oil that was used as a feed stock for olefin production by Shell Chemical in co-located chemicals facilities.
The refinery processes domestic light sweet crude oil (WTI and LLS) that it receives by water.
Transportation fuel products are distributed to southeast markets through a high-capacity truck rack.
Vertex converted the mild hydrocracker to a renewable diesel facility in 2023, while continuing to process crude through the rest of the plant. In 2024 Vertex announced that it was converting the hydrocracker back to fossil refining due to low renewables margins.
