The
Project
Pure
Steam Generator Control System Upgrade
Due to
the existing PSG control system being old and unsupported, Honeyman were engaged
to provide a modern, industry recognised and supported control system.
The
control system upgrade comprised of a DCS solution (Eurotherm EYCON 10 Visual
Supervisor with T2550 rack mounted controller). The existing Kemotron 1902
conductivity analyser was retained, as were all external field instruments.
The
existing control system was fitted with an independent chart recorder to monitor
historical data (feed water and pure steam conductivity). This outdated system
was removed and replaced with electronic data storage, within the EYCON 10.
The
Eurotherm EYCON 10 Visual Supervisor provides the operator with a graphical
process interface, and is used to execute across-network control operations.
Process mimics, historic trend displays, password controls and alarm and event
logs fully inform the operator of system status ensuring compliance with 21 CFR
Part 11. Touch screen features are provided for screen navigation and execution
of operator commands.
Compared to
replacing the entire PSG, the upgrade project not only incurred significant cost
savings but also minimised production down-time. Since completion of the
project, Honeyman have secured the service and maintenance contract for the pure
steam generator and are also involved in steam quality testing exercises.
