Abstract

A method and a device for recovering valuable vapour by refining of fibre material. Formed vapour and the refined fibre material in a closed system are brought to a transportation device 3, 4 and a circulation circuit 5-9 in which the vapour and the milling goods are separated, and the vapour led away through a pipe 11 with a control valve 12. An optional transport flow at a desired vapour pressure is maintained in the transportation circuit for vapour, and the vapour is taken out at the chosen pressure. <IMAGE>
