Al Jubail Petrochemical Plant, Saudi Arabia




Key Data


The Al-Jubail Petrochemical Company (Kemya) owns the plant complex. The company is a joint venture between Saudi Arabian Basic Industries (Sabic), owned by the Saudi Arabian Government, and ExxonMobil.

Saudi Arabia has traditionally only involved the private sector through large multinationals, such as Chevron, ExxonMobil and BP.

Sabic holds half the joint venture and Exxon Chemical Arabia (a subsidiary of the ExxonMobil group) the other half. The plant was established in 1979 and came on stream in 1985.

Expansion of the Al-Jubail Petrochemical Company's plant

"The Al-Jubail Petrochemical Company (Kemya) owns the plant complex. The company is a joint venture."

In November 2008, Sabic and ExxonMobil Chemical signed an agreement to undertake a feasibility study for establishing a new elastomers plant at Kemya. The synthetic rubber plant will have a production capacity of 400,000t/y and require an estimated investment of $5bn.

In May 2011, Sabic and ExxonMobil awarded FEED contracts for the process units of the project to Jacobs Engineering and Mitsui Engineering & Shipbuilding.

Fluor Transworld Services was awarded the FEED contract for associated support facilities.

Technology licence agreements have also been finalised with Continental Carbon Company for its carbon black production technology. Goodyear Tire & Rubber Company has been contracted to provide its SBR and polybutadiene rubber technology.

Ethylene, propylene and polyethylene plant

The project is an ethylene and polyethylene plant in Al Jubail, Saudi Arabia. A major expansion of the plant was started in the fourth quarter of 1998 financed with a loan of about $720m from a consortium of 16 banks, arranged for a term of eight and a half years. The rest of the project was paid for through equity.

The expansion project involved the construction of a 218,000t/y low-density polyethylene plant and an olefin cracker which produces 700,000t/y of ethylene and 200,000t/y of propylene. The plant uses the proprietary technology of ExxonMobil for the high pressure LDPE unit.

The project also included the de-bottlenecking of the company's linear low-density polyethylene to raise capacity by nearly 40% from (615,000t/y to 850,000t/y), which was completed in November 1999. The Olefin III project, started in last quarter 2001, included 800,000t/y feedstock ethylene, 160,000t/y propylene and 25,000t/y benzene.

Thus, the project is a major commitment by Kemya. The new plant cost approximately $1bn. The plant has two more ethylene crackers that were constructed by the Saudi Arabian division of ABB Lummus via a turnkey contract, which uses both hot ends and recovery technology.

Tecnimont Arabia and Tecnimont were the contractors for the LDPE plant. Commercial production began in January 2001.

Ethane and propane feedstock

The de-bottlenecking engineering, procurement and construction services contract for the LDPE plant was awarded to Saudi Arabian Parsons (part of the UK construction group). The plant gets half of its feedstock from ethane and half from propane.

Increased ethylene capacity

Saudi Arabia is seeing a substantial rise in its ethylene capacity as several major projects come on stream. Both the Yanpet 2 project and the Al Jubail project are linked to the company's efforts to have more value-added products. This is also linked to the company's greater investment in R&D.

"Sabic holds half the joint venture and Exxon Chemical Arabia (a subsidiary of the ExxonMobil group) the other half."

The projects have also been made possible by the rising price of crude oil. Saudi Arabian petrochemical production has cheap supplies of feedstock, but high transport costs to the main markets in Asia and Europe.

The higher oil price shifts the competitive advantage by increasing European and Asian producers' costs, making the high Middle East transport costs less important as a proportion of the total cost.

Sabic also created the Jubail United Petrochemical Company. The integrated complex came on stream in the second half of 2004 and has production capacities of more than 1mt/y of ethylene and 460,000t/y of ethylene glycol. Sabic already accounts for nearly 20% of the world's ethylene glycol production. The plant also produces polyethylene and linear alpha olefins (LAO).

In January 2001, Petrokemya awarded a contract for a new plant adding 800,000mt/y of HDPE and LLDPE to current capacity. The contract was placed with Toyo Engineering Corporation of Japan. Petrokemya currently produces 2.5mt/y of various petrochemical and polymer products, including ethylene, benzene, propylene, butadiene, butene-1 and polystyrene.

Sabic's involvement in the Al-Jubail petrochemical plant

Sabic is the biggest petrochemical producer in the Middle East and has been concentrated mainly in Saudi Arabia since its foundation in 1976.

The company is committed to continuing a major petrochemical expansion despite its recent fall in profits, which was brought on by the double whammy of rising feedstock prices and falling petrochemical prices.

ExxonMobil's international prowess

ExxonMobil was formed by the merger of Exxon and Mobil in 1999. It is the second largest ethylene manufacturer in the world. In polyethylene, the company is the leading world supplier. It is also a major producer of oil and gas, as well as many other petrochemical products.

The Al-Jubail Petrochemical Company owns an ethylene and polyethylene plant in Al Jubail.
Part of the expansion project is construction of a 218,000t/yr low-density polyethylene plant.
The project further entailed de-bottlenecking the company's linear low-density polyethylene.
The total project cost is estimated at approximately $1bn.
The Al-Jubail Petrochemical Company (Kemya) is a joint venture.
