Latest Patents
Lars-Erik Åkerlund holds a patent for a method for lignin separation from black liquor involving multiple acidification steps. This method is designed to separate lignin from original black liquor (BL) and includes several phases in sequence. The first precipitation phase involves the precipitation of lignin through the first acidification of the original black liquor by adding a first acid or a mixture of acids. This is followed by a storage phase where the precipitated lignin particles are allowed to increase in size. The process continues with a second precipitation phase, which involves further acidification of the original black liquor by adding a second acid or mixture of acids. By retaining the acidified black liquor for at least 25 minutes during the storage phase, the precipitated lignin particles can grow in size, significantly improving filterability.
