SAUDI ARABIA - The Riyadh Refinery.
Another 95,000 b/d hydrotreater is to be installed at the Yanbu' refinery. By early 2006, the two plants will switch to lower-sulphur diesel production, as part of a government initiative to improve air qualities in the major cities.
The main contract for the first phase was awarded in August 1997 to McConnell Dowell of New Zealand and Petrocon of the US. They built a new control system which replaced an existing one. The contract was part of a plan which integrated the control systems of the domestic refineries of Riyadh, Yanbu' and Jeddah. The plant has a new isomerisation unit, together with a naphtha desulphurisation unit and a distillate desulphurisation facility.
The refinery came on stream in 1975 with a capacity of 15,000 b/d. This was raised to 20,000 b/d in 1977. Work began in 1977 to raise the capacity to 135,000 b/d in a project completed in 1981. The plant processes Khurais crude oil pumped through a 140 km pipeline. During the Gulf crisis in late 1990 its capacity was raised to 140,000 b/d. This has since become its sustainable capacity after some debottlenecking work.
