STAR Aegean refinery details
Located in the Petkim Aliaga complex area, Turkey, the STAR Aegean refinery is a high-complexity high-conversion oil refinery that processes natural gas and refinery fuel gas.
It includes a crude distillation plant with a capacity of 34,023 cubic metres a day (m³/d), a vacuum distillation plant of 13,514m³/d, a 6,067tpd saturated gas plant, and a 703tpd unsaturated gas plant.
A naphtha hydrotreater unit, a kerosene hydrotreater unit, and one diesel hydrotreater unit with capacities of 3,180m³/day, 4,134m³/day, and 10,811m³/day respectively are also installed at the refinery.
The facility also contains a hydrocracker unit (10,493m³/day), a delayed coker unit (6,380m³/day). and a continuous catalytic reforming (CCR) unit with a capacity of 4,452m³/day.
In addition, the refinery features a hydrogen generation unit with a capacity of 3.84 million normal cubic metres per day, a 1,317m³/day saturated liquefied petroleum gas (LPG) Merox unit, and a 422m³/day unsaturated LPG Merox unit.
It also has two sulphur recovery units and a tail gas treatment unit with a capacity of 487tpd of sulphur.
STAR Aegean refinery infrastructure
The STAR Aegean refinery is installed with 63 storage tanks with a combined capacity of approximately 1,640Mt. It features a marine terminal to enable the import of crude oil and export of refined products from the plant. The terminal includes four jetties with double berthing facilities for tankers.
The refinery also includes a waste water treatment unit.
STAR refinery products
The STAR refinery is designed to refine Azeri light, Kerkuk. and URALS oil to produce 4.8Mt of ultra-low sulphur diesel fuel, 1.63Mt of Jet fuel, and 320,000t of LPG a year.
It also produces petrochemical raw materials including 1.61Mt of naphtha and 422,000t of mixed Xylene a year.
Other refined products from the plant include 485,000t of reformates, 692,000t of petroleum coke, and 153,000t of sulphur a year.
The naphtha, LPG, and mixed xylenes produced by the refinery are sent to the Petkim petrochemical plant located adjacent to the refinery.

STAR Rafineri awarded the engineering, procurement, and construction contract for the refinery to a consortium of four companies including Tecnicas Reunidas, KS Engineering, Saipem, and ITOCHU.
The front-end engineering and design (FEED) contract for the refinery was awarded to Foster Wheeler and Fluor Consultants.
Axens provided the hydrotreater units, while FWI provided the crude distillation plant, a vacuum distillation plant, a saturated gas plant, and an unsaturated gas plant.
Honeywell (formerly UPO) was appointed as the main automation supplier for the oil refinery. It also provided a hydrocracker unit, a CCR Reformer unit, a saturated LPG Merox unit, and an unsaturated LPG Merox unit for the plant.
FW USA provided the delayed coker unit, while Technip Benelux provided the hydrogen generation unit and Technimont supplied two sulphur recovery units and tail gas treatment units.
ABB was responsible for providing the transmission and distribution substation, along with other electrical infrastructures for the project, under a contract awarded in March 2016.
Tekfen Construction and Installation Company, Temelsu, Keller Grundbau, and Samm Technology are some of the other contractors involved in the project.
