    摘要: 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.

    摘要: The present invention relates to a method of membrane-filtrating a lignin containing composition in order to obtain a lignin fraction more suitable for further treatments.In particular it relates to treating a liquid lignin composition to obtain a lignin fraction having a desired molecular weight distribution by a membrane filtration. It comprises subjecting the liquid lignin composition to a first membrane filtration with a first filter cut-off adapted to remove species having a first molecular weight thereby providing a permeate with a molecular weight distribution defined by said cut-off. Then, the permeate from the first membrane filtration is; subjected to at least one further filtration step with a second filter cut-off, different from said first filter cut-off to provide a retentate (concentrate) with a molecular weight distribution defined by both the cut-off in the first filter the cut- off in said second filter. A dilution is performed on a desired lignin containing fraction at some point downstream of the first filtration unit. A lignin containing retentate (concentrate) is collected from the further ultrafiltration for further processing.
