Rotork actuators used at Spanish chemical processing plant

news item image
A total of 150 intelligent electric actuators on Rotork’s Pakscan control network have been ordered by a Spanish processing plant.
Some of Rotork’s IQ range of intelligent electric actuators have already been installed at the Quimica Puente Mayorga chemical processing plant in Cádiz.
The remainder are to be installed in the coming months.
The plant is owned by CEPSA, a Spanish multi-national oil and gas company with operations throughout Europe.
The Quimica Puente Mayorga plant is one of the world's biggest producers of linear alkyl benzene, with paraffins, sulphonic acid and heavy alkylate among the other chemicals produced at the plant.
The actuators were installed on gate valves and control the flow of unprocessed fluids, as well as providing Emergency Shutdown (ESD) functionality.
In an emergency, they release the fluids into suction and discharge pumps for isolation.
The actuators have been installed on a double loop system with a Rotork Master Station on a Pakscan control network.
The installation of this control network has enabled CEPSA to reduce their wiring costs at the Quimica Puente Mayorga plant.
Rotork also manufactured a bespoke cabinet to be installed with the Rotork Master Station. While the Rotork Master Station is accessible to senior staff, the cabinet provides an additional access point which has been designed to give site operators the ability to open or close valves in the event of an emergency.
Pakscan was essential for this application, as the space taken up by wiring would have made it impossible to implement via other means.
