Abstract (en)
An impregnation vessel (10) including: a vessel container including an upper inlet (14) to receive cellulosic material; a lower discharge port (27) to discharge the cellulosic material from a discharge section of the vessel container; a convergence section (22) internal to the vessel through which passes a flow of the cellulosic material in the vessel; a cavity (34) between an internal wall of the vessel and the convergence section (22), wherein the cavity (34) has a lower opening to the cellulosic material in the vessel and an upper section shielded from the flow of cellulosic material in the vessel, and an input port in the vessel and opening to the cavity (34), wherein the input port is connectable to a source of hot liquid to be added to the cellulosic material in the vessel.
