Qatar Petroleum (QP) and Qatar Petrochemical Company (Qapco) have officially awarded the US’ Bechtel the project management consultancy (PMC) contract for a planned $7.4bn petrochemicals complex at Ras Laffan in Qatar.

The contract will cover PMC services for the front-end engineering and design (feed) of all the technical packages at the project, which was recently named the Al-Sejeel petrochemicals complex,

MEED reported in June that Bechtel had been awarded the PMC for the scheme.

QP and Qapco plan to plan to build a world-scale complex in the north of the Gulf state that will produce more than 3 million tonnes a year (t/y) of chemicals.

Al-Sejeel will produce 1.4 million t/y of ethylene when completed, which will feed other units at the proposed complex. A further 850,000 t/y of high-density polyethylene, 430,000 t/y of linear low-density polyethylene (LDPE), 760,000 t/y of polypropylene and 83,000 t/y of butadiene will be produced.

The partners signed technology licences in June with two US firms; Univation Technologies for the polyethylene units, and Dow Chemical for the polypropylene units. The construction tender and execution phases will follow in 2014-15. Completion is expected in 2018.

Despite Qatar having ample supplies of ethane feedstock, the cracker will be a mixed-feed of ethane and butane. This will allow more flexibility in terms of products and free up ethane for other schemes. The two partners signed an agreement to build the complex in mid-2012. QP will have an 80 per cent share of the complex, with Qapco taking the remainder.

The ethane cracker will be tendered separately on a design and build basis.

The project is part of Doha’s plans to diversify its natural resources away from liquefied natural gas (LNG) without impacting on its core export industry. The feedstock will come from the Barzan gas field, which is being developed to provide gas primarily for domestic use, especially in heavy industrial sectors, such as chemicals, as well as power generation.
