Ethanol dehydration in Sarpsborg

Borregaard replaced a decades old ethanol dehydration system by a state-of-the-art molecular sieve unit from Vogelbusch. The limited space in the biorefinery recommended a skid construction with minimum footprint. A special feature of the installation is an unusually wide capacity span, which was realized in a fully automated process.
The unit has a maximum output of 105,000 liters of dehydrated ethanol per day. Tailored plant automation allows the operator to perform the required capacity changes in a range of 30 % to 100 % with just one key stroke.
Prefabricated in Austria in three structural steel framings, the plant was shipped and ready for start-up in Sarpsborg within a few weeks, with guarantee runs successfully completed in April 2018.
