    摘要： The present invention describes a method for the treatment of tall oil pitch (TOP), said method comprising heating the TOP and optionally additives including water and steam to a temperature of at least 300° C.; maintaining the temperature in the reactor at 300° C. or higher for a period of time to enable thermal treatment of the TOP to act on components thereof to produce fatty acids and/or rosin acids, and/or derivatives thereof, and/or unsaponifiables and/or derivatives having lower molecular weight compared to the high molecular weight components with molecular weights of at least 350 g/mole present in the original TOP, to yield a modified TOP material with lower viscosity.

    摘要： The present invention describes a process for continuous fractionation of CTO (crude tall oil) to RTD (refined tall diesel), said process comprising:—when removing a stream of TOP (tall oil pitch) the CTO is fed through at least two evaporation zones arranged in series so that one stream of CTO is fed from a first evaporation zone to a second evaporation zone, wherein a TOP stream is produced and fed from the second evaporation zone, wherein a first vapor stream is produced within the first evaporation zone and a second vapor stream is produced within the second evaporation zone and wherein there is a temperature difference of at least 10° C. between the first vapor stream and the second vapor stream; and—feeding the first vapor stream and the second vapor stream into a subsequent fractionation column to produce a stream of RTD from the fractionation column, wherein the first vapor stream and the second vapor stream are being fed to different positions, relative to the column height, in the fractionation column, where different conditions are applied to ensure suitable fractionations of a more fatty acid rich material and a more rosin rich material, respectively, and which different positions in the fractionation column are separated by packing means.
