Yokogawa Wins Major Refinery Control Systems Order from S-Oil Corporation

Tokyo, Japan - July 14, 2016

Yokogawa Electric Corporation announces that its subsidiary, Yokogawa Electric Korea, has received an order to deliver control systems for a new plant that S-Oil Corporation, a Korean oil & gas subsidiary of Saudi Aramco, plans to build at its Onsan refinery complex in the city of Ulsan. The control systems are for a residue fluid catalytic cracker (RFCC)^* and auxiliary facilities that will produce mainly polypropylene and propylene oxides.

The Onsan refinery complex has a capacity of 669,000 barrels of oil per day and produces a variety of fuels, lubricants, and petrochemical products. S-Oil plans to expand its operations by collecting residue oils from this complex and processing them in the RFCC unit to produce polypropylene and other valuable petrochemicals. With this new unit, S-Oil plans to increase its production of high-octane gasoline and targets the annual production of 405,000 tons of polypropylene and 300,000 tons of propylene oxides. This is one of the largest oil refinery expansion projects currently underway in South Korea.

For this new facility, Yokogawa Electric Korea will deliver CENTUM^® VP integrated production control systems, ProSafe^®-RS safety instrumented systems, Plant Resource Manager (PRM^®) field device management software packages, and other products, and will be responsible for the engineering, installation, and commissioning of these systems and the training of plant operators. This is Yokogawa's first control systems order from S-Oil.

Yokogawa believes that it was able to win this order thanks to its successful track record in delivering RFCC control systems in South Korea, the high reliability and long-term stability that its products have demonstrated at oil and petrochemical plants all over the world, and the excellent engineering capabilities of Yokogawa Electric Korea.

Yokogawa will continue to offer high value-added solutions to help its customers improve their competitiveness.

* A facility that uses catalysts to convert residue oils into high-octane gasoline, light oil, and other products
