Abstract: A continuous feeding and discharging system for solid material under high pressure is provided. The system includes a feeding assembly, a high pressure vessel, and a discharging assembly. The feeding assembly includes a raw material hopper that feeds solid raw material, a CO2 feeder that feeds dry ice, and a mixer that mixes the solid raw material with the dry ice to form an impermeable mixture. The high pressure vessel performs an extraction process under a supercritical condition to extract soluble components from the solid raw material. The discharging assembly includes a discharging extruder that receives the solid residue discharged from the high pressure vessel, a binder liquid feeder that feeds binder liquid to mix with the solid residue to form a uniform mixture and compacts the mixture to form impermeable pellets of residue, and a discharging valve that discharges the impermeable pellets of residue from the discharging extruder.

Abstract: In a method for the continuous precipitation of lignin from black liquor black liquor is provided so as to flow as a pressurized flow in a reactor with a dwell time of less than 300 s. An acidifying agent selected from the group of carbon dioxide, acid and their combinations is led to the flow at one or more feeding sites to lower the pH of black liquor. The pH is allowed to decrease by the effect of the acidifying agent in the pressurized flow to the precipitation point of lignin, the pressure of the pressurized flow is abruptly released, and lignin particles are separated from black liquor.

Abstract: Disclosed is a method for the continuous impregnation of wood elements, such as wood chips. The method comprises the subsequent steps of subjecting the wood elements to vacuum, to contact with acetylation fluid, and to impregnation pressure. Preferably, the process is conducted in a plant having conveyors, such as transportation screws, in suitable positions between the zones in which the subsequent process steps are conducted. The impregnation method is used in connection with the acetylation of the wood elements, and preferably is followed by a continuous acetylation process conducted in an acetylation reaction zone downstream of the zone where the impregnation is conducted.
