Abstract
A process is disclosed for fractionating biomass-based material. The process includes evaporating an evaporable part of biomass-based material in a short path evaporator, SPE, to produce a depitched lights fraction in liquid form, and a heavier pitch fraction. The depitched lights fraction may contain depitched tall oil in liquid form, and the heavier pitch fraction may contain tall oil pitch, TOP.
