Title: Method of intensifying the washing of a fibre suspension
Inventor: HENRICSON KAJ
IPC: D21D1/40
Filed: 1987-12-16
Granted: 1992-01-14
Abstract: Abstract Method of intensifying the washing of a fibre suspension The present invention relates to a method of intensifying the washing of a fibre suspension.   In particular the present invention relates to decreasing the lignin content of a fiber suspension by extracting.   Lignin removal is usully carried out at a consistency of less than 3 % whereby heating consumes much energy.  The method of the invention allows a considerable increase in the consistency of the suspension which results in that the energy consumption is decreased to a fraction of the one required by prior art methods.   A characteristic feature of the method of the invention is that dry substance and chemicals contained in the fibers are extracted at a raised pressure and temperatu-re.
