Project description
• Duration: 04/2006-06/2010• Project funding: Academy of Finland• Project goals:
– Develop a data-based FTC strategy for countering the effects of faults in the control system sensors, analyzers and actuators
– Improve the performance and profitability of the industrial dearomatization process located at Neste Oil Naantali refinery, Finland

Project results
• Improved control performance and quality of end products– Lower off-spec production– Lower energy consumption
• Enhanced profitability– Less than a year payback
period for the implementation of the FTC strategy to the target process
