Abstract
It is disclosed a continuous process for soaking a ligno-cellulosic biomass stream in an extraction solution comprising water and dissolved water soluble species derived from a previously treated ligno-cellulosic biomass, wherein the soaked ligno-cellulosic biomass stream is optionally rinsed with a rinse solution stream to produce a soaking liquid. The electrical conductivity of the extraction solution and/or the soaking liquid are controlled to a value in a suitable target range by regulating one or more dilution streams.The disclosed process is useful to remove non-ligno-cellulosic water soluble compounds from the ligno-cellulosic biomass with a low consumption of water.
