THE Linde Group and Sadara Chemical Company (Sadara) have 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 (Saudi Aramco) and The Dow Chemical Company (Dow).

“This contract is an excellent opportunity from several perspectives,” states Professor Dr Aldo Belloni, member of the executive board of Linde. “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.”

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 including synthetic fibres.
