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). A second plug screw feeder is arranged to receive the diluted material and to compress, dewater and transport the material to the second reactor unit, wherein the second screw feeder is arranged to operate at a pressure being higher than the pressure of the first plug screw feeder.
