FRACTIONATION OF BIOMASS-BASED MATERIAL

A process is disclosed for fractionating biomass-based material. The process comprises evaporating an evaporable part of biomass-based material (104) in a short path evaporator, SPE (105), to produce a depitched lights fraction (106) in liquid form, and a heavier pitch fraction (107). The depitched...

Zusammenfassung:	A process is disclosed for fractionating biomass-based material. The process comprises evaporating an evaporable part of biomass-based material (104) in a short path evaporator, SPE (105), to produce a depitched lights fraction (106) in liquid form, and a heavier pitch fraction (107). The depitched lights fraction (106) may contain depitched tall oil in liquid form, and the heavier pitch fraction (107) may contain tall oil pitch, TOP. Un procédé est décrit pour le fractionnement dun matériau de biomasse. Le procédé comprend lévaporation dune partie évaporable dun matériau de biomasse (104) dans un évaporateur à trajet court (105), pour produire une fraction de lumières dont on extrait le brai (106) sous forme liquide, et une fraction de pas plus lourde (107). La fraction de lumières dont on extrait le brai (106) peut contenir du tallöl dont on extrait le brai sous forme liquide, et la fraction de brai plus lourd (107) peut contenir un brai de tallöl.
