The Linde Group has signed a long-term industrial gas supply contract with Sadara Chemical Company. The agreement will supply a facility soon to become the world’s largest chemical complex ever built in a single phase.

The contract will secure the supply of carbon monoxide (CO), hydrogen (H2) and ammonia (NH3) to the Sadara facility in Jubail, Saudi Arabia.

The on-site gases agreement will include a HyCO facility for the production of CO and H2 plus an ammonia plant. Linde will be investing a total of $380m in the project.

Professor Dr Aldo Belloni, Member of the Executive Board of Linde AG, described the contract as an, “excellent opportunity from several perspectives.” He explained, “It is Linde’s largest on-site petrochemical project in this region, and our first in Jubail. It thus strengthens our position as a global leader in the generation and supply of carbon monoxide for MDI and TDI production plants at integrated chemical hubs.”

“The petrochemical industry is expanding rapidly in Saudi Arabia. We expect that this growth will give added momentum to the expansion of our gases and engineering business in the Middle East,” added Belloni.

Sadara established in October 2011, is a joint venture developed by Saudi Arabian Oil Company and The Dow Chemical Company.

Linde’s Engineering Division will design, deliver and construct the new turnkey gases facilities at Sadara’s site in the Jubail 2 petrochemical cluster. The company will be building a two-stream HyCO plant, plus a single-stream NH3 unit producing waterless liquid ammonia.

Linde will also install a large NH3 storage tank, resulting in a sophisticated supply concept which will enable the plant to run smoothly and reliably at all times. The production units are scheduled to be ready in 2015. Once built, they will be operated by Linde’s Gases Division. Linde is setting up a local gases company for on-site support.

Sadara plans to use carbon monoxide, hydrogen and ammonia primarily for the production of aromatics, isocyanates (MDI and TDI), amines and hydrogen peroxide. Methylene diphenyl diisocyanate (MDI) and 2,4 toluene diisocyanate (TDI) are used in the production of polyurethanes  – a key component in products ranging from synthetic fibres through to insulating foam.
