Fisher 42-in. antisurge valves in Saudi olefin project

MARSHALLTOWN, IOWA, February 23, 2009 --  Emerson has been awarded an order for the installation of technologically advanced Fisher control valves at the Saudi Kayan petrochemical complex in Al Jubail Industrial City, Saudi Arabia. For the project, Emerson will supply 780 Fisher digital control valves including the largest 42-inch Fisher antisurge valve ever to be built.  

Scheduled for operation in 2010, and with an annual production capacity exceeding 6 million metric tons of (petro) chemical products, the Saudi Kayan Petrochemical Company, an affiliate of the Saudi Basic Industries Corporation (SABIC), is one of the major suppliers in the petrochemical industry.

The use of high performance valves in critical applications is of significant importance to the profitability of a plant. Fisher digital valves will enable predictive monitoring of the processes and digital-valve performance, supporting proactive maintenance that addresses problems before they become issues that affect plant performance.

Superior dynamic performance of the 5-meter, 11,000-kg large valve with Fisher optimized technology will help ensure a smooth startup for the plant in 2010.  
This largest-ever Fisher FB valve will be used in the cracked gas compressor first stage to provide surge protection.

Providing high reliability, tight control, fast stroking, and easy tuning, the anti-surge valve features a high-seal graphite packing to eliminate fugitive emissions, Whisper III trim to reduce noise and vibration, a cushioned actuator, Fisher Fieldvue DVC6000 Series-PD instrument and optimized digital valve (ODV) technology to provide fast stroking with controlled deceleration, high resolution, and minimal overshoot. There are twelve valves of various sizes with ODV) technology in the order.  

Fisher valves with Fieldvue digital valve controllers are key components of Emerson’s PlantWeb digital plant architecture that networks process automation systems and instrumentation to provide efficient operations and predictive technology-driven maintenance for process facilities worldwide.
