Abstract
The invention relates to a method for treating biomass (). In a step (S), biomass () and an impregnation liquid are fed into a first reactor unit () such that the biomass () is impregnated with the impregnation liquid while the biomass () is transferred through the first reactor unit () by a conveyor means (). In another step (S), the impregnated biomass () is transferred from the first reactor unit () to a separation unit (), wherein at least a part of the impregnation liquid is separated from the impregnated biomass () within the separation unit. In a step (S), the separated impregnation liquid is discharged from the separation unit (), such that a first part () of the impregnation liquid is recirculated back to the first reactor unit (). The invention further relates to a system for treating biomass ().
