Longannet Condensate Polishing Plant refurbishment
23 Jan 2012
Capula has won a significant contract with Scottish Power (part of the Iberdrola Group) for the refurbishment and modernisation of the Condensate Polishing Plant on the four 600MW generating units at Longannet power station, Scotland.
The Condensate Polishing Plant is used to regenerate the water used in the boiler cycle to minimise plant corrosion which can happen as a result of chemical properties in the demineralised water degrading over time.
Capula's scope of work will cover the complete refurbishment of the control and instrumentation systems, including the replacement of valves and orifice plates, installation of new electrical actuators, modifications to plant pipework and improvements to the plant drainage systems. In addition, Capula will also carry out civil works, installation of electrical cabling and network integration.
Integrating fully into the plant DCS system, Capula's solution will enable the plant to be supervised and monitored from the main control room, while the improved diagnostics and instrumentation will enable better maintenance of the plant and accurate process control. Delivery is already in progress, with commissioning scheduled for April 2012.
“Capula was chosen for this project due, in part, to our extensive experience of working on the DCS systems at Longannet,” said Chief Executive Roger Turner, “Our excellent track record in the automation of condensate plant polishing and water treatment plant control schemes on other power plants was also a contributing factor.”
