Abstract: The invention relates to a process for making a purified lignin composition comprising a carrier liquid suitable for processing in a refinery. It comprises providing an aqueous lignin composition comprising lignin, cooking chemicals and water and adding a carrier liquid to the aqueous lignin to provide an organic phase. Then all or substantially all the water is removed from the composition. The lignin composition is processed to make the lignin more soluble in the carrier liquid in order to transfer more of the lignin to the organic phase. Cooking chemicals are removed, suitably by of washing by liquid/liquid extraction using a washing liquid. Finally washing liquid is removed.
