UPM-Kymmene Oyj (Helsinki, Finnland) has selected Siemens Energy AG (Munich, Germany) to supply electrification, automation and digitalization (EAD) packages for a next-generation biorefinery currently under construction in Leuna, Germany.
The biorefinery will be the first industrial-scale facility of its type ever built. It will apply novel process innovations to sustainably convert 100% wood into bio-based mono-ethylene glycol (MEG) and mono-propylene glycol (MPG), as well as renewable functional fillers (RFF). Both MEG and MPG, as well as functional fillers have traditionally been produced using fossil-based raw materials. UPM will provide alternatives to considerably reduce the CO2 footprint of end-products such as PET bottles, packaging materials, textiles or rubber products used in various automotive applications. Siemens Energy’s scope of supply for the project includes:
- Electrification: mill-wide medium- and low-voltage power distribution system and drive system (motor control center, variable speed drives, motors)
- Automation: Distributed control system (DCS) for multiple process areas and remote I/O cubicles (total of 9,000 process objects), including safety and ATEX functions for explosive atmospheres
- Digitalization: Complete digital twin for the entire plant, covering the mill’s whole life cycle – from integrated engineering to integrated operation.
The Leuna Biorefinery will be a big step for UPM to expand its business into wood-based biomolecular products and solutions.
“We are confident that the bio-based mono-ethylene glycol, mono-propylene glycol, and renewable functional fillers made in Leuna will meet the strong demand of customers and end-users looking to change towards a truly sustainable portfolio,” says Juuso Konttinen, vice president UPM Biochemicals. “By implementing Siemens Energy’s digitalization solutions and digital twin, we can help ensure safe and efficient operations.”
The biorefinery is scheduled for start-up in late 2022. When fully operational, it will have a total annual capacity of 220,000 tons.
