The technology group Linde and Sadara Chemical Company recently signed a long-term contract that will see Linde supply Sadara with carbon monoxide (CO), hydrogen (H2) and ammonia (NH3) at a chemical complex now being built by Sadara in Jubail, Saudi Arabia, which will be the world's largest chemical complex ever built in a single phase.

The on-site gases supply contract includes a HyCO facility for the production of CO and H2 plus an ammonia plant. Linde will be investing $380 million in the project.

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

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 will 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 - an essential component in many products ranging from synthetic fibres through insulating foam and adhesives to mattresses and car seats.

Sadara will construct, own and operate a world-scale integrated chemicals complex in Jubail Industrial City II in Saudi Arabia. Sadara will have a differentiated product mix, most of which are produced locally for the first time. This differentiation will create further growth opportunities for conversion and downstream industries in the adjacent PlasChem Park.
