Al Sejeel Petrochemicals, Qatar Overview

Scope of Work Project management
Value $7.4 billion
Schedule 2013–2018
Business Oil, Gas & Chemicals

Bechtel was chosen in 2013 to serve as project manager for the Al Sejeel mega-petrochemical complex in Ras Laffan, about an hour north of Doha, the capital.

Anchored by a world-scale ethylene cracker, Al Sejeel will substantially add to Qatar's economic growth, increasing the petrochemicals sector's capacity to 23 million metric tons per year by 2020—an increase of 130 percent. The complex will produce ethylene, high-density polyethylene, linear low-density polyethylene, polypropylene, and butadiene, which will be used in everything from cars and mobile phones to planes, food wrap, and medical equipment.
Target markets for Al Sejeel's output are growth sectors in Asia, Africa, and Latin America. 

The feedstock for the mixed-feed cracker will be a combination of ethane, butane, and naptha sourced from natural gas projects in the north of Qatar. 

“Bechtel’s contribution…will be strategic, as Bechtel benefits from extensive experience and is a leader in the construction of petrochemical plants all around the world.” —Dr. Mohammed Yousef Al-Mulla, vice chairman and CEO of Qatar Petrochemical Company

Now under construction

Bechtel is providing project management services during the course of the Al Sejeel effort. It began with the front-end engineering design phase to ensure the project's quality, safe, and timely construction.

Our customer is a venture owned 80 percent by Qatar Petroleum and 20 percent by Qatar Petrochemical Company.

Al Sajeel's polypropylene production facility will produce homopolymers, random copolymers, and impact copolymers, which are used in packaging, durable goods, automotive parts, non-wovens, fibers, and consumer applications.

The immense cracker at the heart of Al Sejeel will use mixed hydrocarbon feedstock to produce 1.4 million metric tons per year of ethylene.

Downstream units at the complex will annually produce: 

  • 850,000 metric tons of high-density polyethylene
  • 430,000 metric tons of linear low-density polyethylene
  • 83,000 metric tons of butadiene
  • 760,000 metric tons of polypropylene 

No Stranger to Qatar

In the early 1990s, a Bechtel-led partnership played a large role in the country's massive and highly productive North Field offshore natural gas development project—not far from Al Sejeel. The $1.4 billion first phase alone included:

  • an offshore productions and processing complex, including eight offshore platforms
  • gas and liquid pipeline networks
  • onshore processing facilities.

More recently, we completed Hamad International Airport in Doha.
