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.
