Publication number: 20230160145Abstract: The present invention relates to a process and a system for the at least partial removal or exchange of solvent from/in a suspension comprising microfibrillated cellulose (MFC), specifically the at least partial removal of solvent from a suspension comprising microfibrillated cellulose having a comparatively high solvent (water) content to a relatively lower solvent content. Accordingly, the solids content of the microfibrillated cellulose increases during the the step of at least partial removal of solvent from a suspension comprising process, in particular from a first solids content in the range of from 0.1% weight by weight (“w/w”) to 6% w/w, preferably 1% weight by weight (“w/w”) to 5% w/w, up to a second solids content of above 5% w/w, preferably to a solids content of from above 5% w/w-50% w/w, further preferably to a solids content of from above 5% w/w-25% w/w. In a separate aspect, a solvent exchange tep after the at least partial removal of a first solvent is also part of the present invention.Type: ApplicationFiled: December 19, 2019Publication date: May 25, 2023Inventors: Hans Henrik Øvrebø, Seid Ali Moosavi Far

Patent number: 11577863Abstract: The present invention relates to a system for the compact packaging of microfibrillated cellulose, which comprises a packaging, which comprises at least one polymer material. Said packaging encompasses a content that essentially consists of microfibrillated cellulose (“MFC”) that is present as a suspension in a solvent. The resulting system is of an essentially round or essentially rectangular or oval outer circumference, as defined by the dimensions of the packaging once fully filled out by the content. The system of the invention has the advantage, among others, to provide a solid and firm essentially round packaging shape. The resulting units of packaged MFC can be easily stacked on a pallet. The packaging maintains the water retention capacity of the suspension (paste). The present invention also relates to a process for making such a system.Type: GrantFiled: September 18, 2018Date of Patent: February 14, 2023Assignee: Borregaard ASInventors: Hans Henrik Øvrebø, Antje Gonera, Jarle Wikeby
