Steam profiler generates energy savings at Smurfit Kappa Nettingsdorf

Smurfit Kappa Nettingsdorf is one of the leading producers for Kraftliner in Europe. Their PM6 has a capacity of up to 450,000 ton/year. Energy efficiency is a key element in their management system in order to improve operational costs and reduced environmental impact. An existing steambox was found to work inefficient, and after careful evaluation of the current process parameters and assessment of improvement potential, Nettingsdorf decided to replace this steambox by state of the art Valmet IQ Steam Profiler. Target was to achieve a significant decrease in specific steam consumption for the paper machine.

The project target has been met. Due to improvements in steambox effectiveness and optimizations in CD moisture profile control we achieved a next step forward towards first class energy efficiency.”
