Rotork and Foxboro control refineries

The giant Reliance Oil refinery at Jamnagar in India and the equally huge Formosa Plastics Chemical Company’s Mai-Liao refinery at Kao Hsiung in Tiawan are both near to completing extensive new tank farm and storage facilities. In both cases, Rotork has been awarded the valve actuation contracts and is once again supplying market leading ‘non-intrusive’ IQ intelligent actuators.

At both refineries the majority of the Rotork actuators are networked together on Rotork Pakscan 2-wire digital control loops for communication with Foxboro Intelligent Automation distributed control systems (DCS). Each Pakscan loop is capable of monitoring up to 240 actuators via a master station that interfaces with the DCS. Each master station creates a data base containing information from all the valve actuators on the loop it controls, which is continuously updated and accessed using a Modbus protocol.

For Jamnagar, 600 IQ actuators with Exeeco gearboxes have been delivered to the Italian factory of Tyco Valves and Controls to be fitted to Vanessa Series rotary process valves. A further 54 IQ actuators have been supplied to the German valvemaker Adams for the same project. In Taiwan, 134 IQ actuators and Exeeco gearboxes will operate tricentric butterfly valves manufactured locally by Value Valves.
