The Iraq-based State Company of Oil Projects (SCOP) is in the process of constructing the Karbala Refinery, which will use cutting-edge refining and automated control processes to optimize the production of petrol, jet fuel, gas and fuel oil and asphalt. When the facility is open in 2020, it is expected to have a refining capacity of 140,000 barrels of crude oil per day (bpd).
Rotork, the global manufacturer of industrial flow control equipment with locations throughout the USA, will be supplying large quantities of IQ3 non-intrusive intelligent electric valve actuators, designed specifically for automated flow control systems in hazardous environments. The IQ3 actuators are expected to facilitate the reliable, efficient and safe operation of the refinery.
Comprehensive operational data, including valve torque profiles stored in actuator dataloggers, can be downloaded and analyzed to enable predictive maintenance and optimize plant performance. For critical areas, actuator duties will include the provision of a Safety Integrity Level 2 (SIL2) Emergency Shutdown (ESD) function.
The SIL system identifies the requirements for a Safety Instrumented System (SIS). These actuators are equipped with the Rotork SIL safety module, which monitors the standard IQ3 control board and provides diagnostic coverage and redundant control in order to perform the desired safety function. A safety function status relay provides remote indication of the actuator availability and the redundant safety function operation, with the same status duplicated locally on the actuator display.
