Abstract: A system for treatment of a biomass material, said system comprising: a first vessel (3) in which said biomass material is treated under a first pressure; a second vessel (5) in which said biomass material is received and held at a second pressure which is lower than the first pressure; a transporting pipe (7) connecting an outlet (9) of the first vessel (3) with an inlet (11) of the second vessel (5) for transporting the biomass material from the first vessel to the second vessel; and a valve (15; 15′; 15) arranged in said transporting pipe (7), said valve being configured for controlling the flow of biomass material and fluid in the transporting pipe (7), wherein said transporting pipe (7) is asymmetrically connected to an outlet (33′; 33) of said valve (15; 15′; 15) such that a generated jet stream of biomass material delivered out from the outlet (33′; 33) of the valve (15; 15′; 15) is received closer to a transporting pipe longitudinal central axis (A1) than if the outlet (33′; 33) of the valve (15; 15′; 15) and the transporting pipe (7) would have been connected symmetrically.

Abstract: According to the present invention, there is provided a cleaning system for biomass material handling systems and methods for such system. The cleaning system for a biomass material treatment stage in a continuous process system includes a hydrolysis or pre-hydrolysis reactor, a feeding arrangement is arranged to continuously feed biomass material to an inlet of the reactor, wherein reactor includes a reactor screw for moving the biomass material through the reactor and a discharge pipe including a discharge screw for continuously discharging treated biomass material. At least one high-pressure cleaning nozzle is arranged inside a housing of said reactor, wherein the at least one high-pressure cleaning nozzle is arranged to eject cleaning agent at predetermined intervals during operation of the reactor.

Abstract: A reactor arrangement for pre-hydrolysis of biomass material. The reactor arrangement comprises a reactor vessel arranged substantially horizontally, wherein the vessel comprises an inlet for receiving the biomass material arranged at an upper portion of the vessel. The inlet may be arranged at a first longitudinal end of the vessel. The vessel may furthermore comprise an outlet at a second longitudinal end of the vessel. The reactor arrangement further comprises a set of steam injection orifices arranged to inject or supply steam into the reactor vessel. The set of steam injection orifices comprises at least two orifices arranged below the inlet at a distance from each other. The at least two orifices may be arranged at a distance from each other in the lateral direction of the reactor vessel. Furthermore, a method for pre-hydrolysis treatment of biomass in a substantially horizontal reactor vessel is provided.
