EIM For Coker Application Dependable EIM Electric Actuators Improve Delayed Coker Operational Uptime and Reliability at a Louisiana Refinery

[File Name or Event] Emerson Confidential 27-Jun-01, Slide 2 Refinery in Louisiana CHALLENGES –To reduce coker downtime caused by competitors’ products failing prematurely –To deploy actuators that will reliably operate on the refinery’s delayed coker units under extreme conditions: Operating temperatures of up to 700°F (375°C) Presence of corrosive water and sulfur in the environment High torque and thrust loads Water hammer and vibration in the operating environment Coking operation requires actuators to divert process in a precisely timed event Applications: Operating ball valves, water purge and slurry gate valves on delayed coking unit process valving. Refinery in southwest Louisiana, USA

[File Name or Event] Emerson Confidential 27-Jun-01, Slide 3 Refinery in Louisiana SOLUTION –EIM 2000 M2CP actuators have been selected for its proven track record. Quality materials and construction allowing for high-temperature operation Superior powder coating on all surfaces and durable ductile-iron housing protects against corrosion Durable construction that withstands high torque and thrust loads without cracks and deformation Design of the package, gear assembly and electrical enclosure protects against the damaging effects of vibration and water hammer Controls and functionality allow the precise timing and execution of cycles “EIM’s actuators have definitely improved the electric actuator reliability, decreased downtime and improved productivity in our coker units. Their performance has made them the preferred actuator of our unit operators.” Instrument Reliability Engineer
