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 42in Fisher anti-surge valve ever to be built (5m, 11,000kg). 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. 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. The complex is scheduled for operation in 2010, and will have an annual production capacity exceeding 6 million metric tons of (petro) chemical products.
