  • Patent number: 10625190
    Abstract: A steam separation unit for separation of steam from lignocellulosic biomass material in a hydrolysis process includes a treatment vessel including a separation section and a biomass collection section. The separation section is arranged with at least one inlet for receiving at least partly hydrolyzed biomass material mixed with steam and at least one control outlet for discharging the steam from the vessel. A biomass collection section arranged to be filled at least partly with liquid during operation and coupled to the separation section to collect the biomass material after separation from steam, wherein the biomass collection section includes a mixing element for mixing the biomass material with liquid and at least one control valve for discharging biomass material mixed with liquid. A system for hydrolysis of lignocellulosic biomass material including such a separation unit is also presented.

  • Patent number: 10047408
    Abstract: An arrangement for feeding and dewatering lignocellulosic material in a hydrolysis process between a first reactor unit, where the material is partly hydrolyzed, to a second reactor unit, wherein the first reactor unit operates at a first pressure and the second reactor unit operates at a second pressure being higher than the first pressure. The arrangement includes a first plug screw feeder arranged to receive the partly hydrolyzed material from the first reactor unit and being arranged to compress, dewater and transport the material, wherein the first screw feeder is arranged to operate at a pressure being higher than the first pressure. A dilution vessel is coupled to receive material from the first plug screw feeder and including a liquid inlet for receiving liquid to wash the material, wherein the dilution vessel is arranged to maintain or increase the pressure (PDM).
