Borealis Polymers Oy produces ethylene and other petrochemical products at its ethylene cracker in Porvoo, Finland. In year 2003, Borealis had already used NAPCON Controller Advanced Process Control (APC) for several years, but wanted to still further increase profit by augmenting the APC application base with an optimizer. Borealis ordered a Dynamic real-time Optimizer, NAPCON Optimizer from Neste Jacobs, which was taken into operation at the end of year 2004.
Let us listen to Borealis Polymers’ summary on almost 10 successful years of APC and optimization:
Principal optimization specialist, Dr. Stefan Smeds, Borealis Polymers: “For the first operational year of NAPCON Optimizer, we recorded a profit increase of 12.5 million USD per annum thanks to better optimization against process constraints. Our estimate is that this on-line optimizer has continued to add the same amount of annual profit ever since then, meaning that we believe to have passed the cumulative profit milestone of 100 million USD. This was achieved by investing in NAPCON Optimizer technology and software package. However, to keep on-line optimization running successfully requires active follow-up and adjustments by our specialists as process knowledge and process behavior change over time, but that is definitely worthwhile the effort, thanks to the huge benefits it brings in”.
