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.

In an improved method of distilling fluids, some or all of the fluid is recovered as distillate and the fluid is situated in the shell side of a first shell and tube heat exchanger. The fluid to be recovered as distillate is successively boiled, demisted, compressed and then introduced into upper ends of the tubes. A second shell and tube heat exchanger is located below the first heat exchanger, and distillate from upper ends of the tubes in the second heat exchanger are arranged to receive distillate liquid and/or vapor from the lower ends of tubes of the first heat exchanger. The fluid is located in the shell of the second heat exchanger and that fluid is heated but is not boiled. A mechanism is provided to supply at least some of the heated fluid to the shell of the first heat exchanger.
