ESD systems for sulphur-free diesel production
Emergency shut down (ESD) systems from HIMA are to be used in the Porvoo refinery in Finland in a new production line for sulphur-free diesel, ensuring reliable operation of the plant
This system must meet very high standards.
On the one hand, in terms of system safety because of the extremely high potential hazards it poses to people and the environment and, on the other, in terms of system availability because aircraft have a constant demand for fuel.
This system is now being reliably monitored by safety-related controllers from Hima Paul Hildebrandt + Co KG, which is headquartered in Germany.
The ESD system (Emergency Shutdown System) from Hima is replacing an old relay-based safety system, which was no longer able to meet the airport expansion plans.
Six safety-related controllers of type H41q (IEC 61508/SIL 3) are being used to meet the requirements of a safety-related network with safe-ethernet which is based on standard Ethernet.
The ESD system is monitoring a large number of shut-down valves, which are positioned in zones along the fuel line, as well as the feed pumps in order to ensure safe shut-down in case of an emergency.
Each of the six H41q systems processes approximately 70 safety-related signals and is responsible for monitoring one zone.
Hima systems are integrated into the airport's "Infrastructure Management and Control System" (IMCS) via OPC.
Furthermore, the safety controllers are connected to a SCADA system, which is used for visualising purposes, via an OPC interface.
The safety system from Hima was successfully chosen in the tender because of its cost-effective advantages, as well as the system openness and its compact design. Request a free brochure from Hima Paul Hildebrandt ...
