    Abstract: The present invention provides a method for separation of lignin from black liquor comprising the following steps: a) Precipitation of lignin by acidifying black liquor and thereupon dewatering, b) suspending the lignin filter cake obtained in step a) whereupon a second lignin suspension is obtained and adjusting the pH level to approximately the pH level of the washing water of step d) below, c) dewatering of the second lignin suspension, d) addition of washing water and performing a displacement washing at more or less constant conditions without any dramatic gradients in the pH, and e) dewatering of the lignin cake produced in step d) into a high dryness and displacement of the remaining washing liquid in said filter cake, whereby a lignin product is obtained which has an even higher dryness after the displacement washing of step e). The present invention also provides a lignin product or an intermediate lignin product obtainable by the above method. The present invention also provides use, preferably for the production of heat or chemicals, of said lignin product or said intermediate lignin product.
