  • Publication number: 20220298725
    Abstract: The invention relates to method for producing viscosity controlled cellulosic material having a viscosity value in a range between 150 ml/g and 500 ml/g in a continuous process, the method comprising the following steps: i) forming a cellulose-water mixture (15) comprising water and chemically treated wood-based cellulosic material, the cellulose-water mixture (15) having a dry matter content between 3% and 20%, ii) treating the formed cellulose-water mixture (15) in a plasticization step (100) at a temperature between 130° C. and 200° C., and a pressure between 3 bars and 15 bars, at least 5 minutes and 120 minutes at the most, while mixing the cellulose-water mixture (15), and feeding hot water and/or water steam to the cellulose-water mixture, thereby obtaining a treated mixture (18), and iii) depressurizing the treated mixture (18) in a depressurizing step (105) in a controlled manner, thereby obtaining the viscosity controlled cellulosic material (20).

  • Patent number: 8816105
    Abstract: The present invention relates to a method and apparatus for purifying crude tall oil. The purification method comprises a first purification step (2) for separating at least solids (8) from the crude tall oil and producing solids free crude tall oil, and after the first purification step (2) a second purification step (4) for separating water (14) from the solids free crude tall oil. The purification apparatus comprises at least one solids separator (3, 5?) for separating at least solids (8) from the crude tall oil and producing solids free crude tall oil, and at least one water separator (5, 9) arranged downstream of the solids separator (3, 5?) in the flow direction of the crude tall oil for separating at least water (14) from the solids free crude tall oil.
