A method for the impregnation and steaming of chips during the manufacture of chemical pulp comprising following steps; a) chips are continuously fed without preceding steam treatment to the top of an impregnation vessel where impregnated chips are fed out from the bottom of the vessel, b) hot impregnation fluid at a first temperature above the boiling point of the hot impregnation fluid is added to the impregnation vessel, via a pipe having the outlet end located below a chip level (CH LEV) established in the impregnation vessel and at a distance from the walls of the impregnation vessel, preferably in the centre, such that steam is released into the chip volume for steaming the chips, c) the impregnation fluid added establishes a fluid level (LIQ LEV) in the impregnation vessel and where the chip level (CH LEV) lies at least 1-2 meters, preferably 3-5 meters, over the fluid level and where the pressure at the top of the impregnation vessel that is essentially at the level of atmospheric pressure, ±0.5 bar(g) preferably ±0.2 bar(g), d) that a withdrawal of a first impregnation fluid for a first use takes place from the vessel at the level of the fluid level (LIQ LEV), from a first withdrawal volume located behind a first screen row mounted in the wall of the impregnation vessel, e) characterised in that an additional withdrawal of a second impregnation fluid takes place from the vessel at a level below the first screen row, from a second withdrawal volume located behind a second screen row mounted in the wall of the impregnation vessel, said level below the first screen row not exceeding the diameter of the impregnation vessel, and wherein the second impregnation extraction fluid at least in part is returned into the centre of the impregnation vessel which is of different use than the first use of the first impregnation liquid. a) chips are continuously fed without preceding steam treatment to the top of an impregnation vessel where impregnated chips are fed out from the bottom of the vessel, b) hot impregnation fluid at a first temperature above the boiling point of the hot impregnation fluid is added to the impregnation vessel, via a pipe having the outlet end located below a chip level (CH LEV) established in the impregnation vessel and at a distance from the walls of the impregnation vessel, preferably in the centre, such that steam is released into the chip volume for steaming the chips, c) the impregnation fluid added establishes a fluid level (LIQ LEV) in the impregnation vessel and where the chip level (CH LEV) lies at least 1-2 meters, preferably 3-5 meters, over the fluid level and where the pressure at the top of the impregnation vessel that is essentially at the level of atmospheric pressure, ±0.5 bar(g) preferably ±0.2 bar(g), d) that a withdrawal of a first impregnation fluid for a first use takes place from the vessel at the level of the fluid level (LIQ LEV), from a first withdrawal volume located behind a first screen row mounted in the wall of the impregnation vessel, e) characterised in that an additional withdrawal of a second impregnation fluid takes place from the vessel at a level below the first screen row, from a second withdrawal volume located behind a second screen row mounted in the wall of the impregnation vessel, said level below the first screen row not exceeding the diameter of the impregnation vessel, and wherein the second impregnation extraction fluid at least in part is returned into the centre of the impregnation vessel which is of different use than the first use of the first impregnation liquid.
