The 4,000MW combined cycle power plant, the largest of its kind in the world, will use approximately 90,000bpd of vacuum residue from the refinery and further provide electricity, hydrogen and water for the refinery, and convey the excess power to the national grid.
A hydrocracker unit will comprise two parallel trains with a combined capacity of 54,500bpd. The diesel hydrotreater plant will comprise two trains with a capacity of 87,500bpd each.
Jazan Refinery will implement technologies licensed to Saudi Aramco by Axens, including the naphta hydrotreating process for feedstock purification, aromising continuous catalyst regeneration (CCR) reforming process for producing aromatics, C5/C6 isomerisation process for the production of gasoline, ParamaX process for paraxylene and benzene production, and Prime-D gas oil desulfurisation hydrotreater for the production of ultra low-sulfur diesel (ULSD).
Chevron's ISOCRACKING technology has also been licensed for the project.
The contracts for front-end engineering and design (FEED), as well as project management services (PMS), for the refinery and marine terminal were awarded to KBR in February 2011. The company was further awarded the FEED contract for the integrated power plant in November 2012.
A $900m contract for the hydrocracker and diesel hydrotreater facilities was awarded to Técnicas Reunidas (TR). The engineering, procurement and construction (EPC) contract for the benzene and paraxylene facilities was awarded to JGC Corporation.
Siemens was awarded the $966.8m contract for the supply of the power plant components. The contractual scope includes the supply of ten SGT6-5000F type gas turbines for synthesis gas (syngas) and diesel fuel, five steam turbines, 15 generators and ten heat recovery steam generators.
The EPC contract for the tank farms within the northern and southern areas of the refinery was awarded to Petrofac, while the EPC contract for the utility facilities and buildings was awarded to Hitachi Plant Technologies.
Other major contractors for the project include Al-'Ali Al-Ajmi Group, Hanwa Engineering & Construction, and SK Engineering & Construction. Orion has been awarded the contract by Hanwha Engineering & Construction to supply its class 150 and 300 through conduit gate valves for the project.
Elecotherm Consulting Engineering is the adviser for the thermal insulation and coating activities for the project.
