The method and an arrangement are for improved impregnation of chips in association with the manufacture of chemical cellulose pulp. Un-steamed chips are fed into an impregnation vessel (30) in which a fluid level (LIQ_LEV) is established under the highest level (CH_LEV) of the chips. An improved impregnation arrangement for the chips is obtained by the addition of impregnation fluids (BL1/BL2/BL3) with increasing temperatures at different heights (P1, P2, P3), and by the establishment of a counter-flow zone (Z1) in the uppermost part of the impregnation vessel. The requirement for steaming may in this way be dramatically reduced while at the same time the amount of expelled waste gases may be minimized. A major part of the volatile compounds present in the wood are bound to the impregnation fluid (REC) that is withdrawn.       Recently Added Patents Pteridines and their use as agrochemicals Managing acoustic noise produced by a device Primary production of elements Method and apparatus to perform automated page-based tier management of storing data in tiered storage using pool groups Counter rotation subsurface current generator Elastomeric nanocomposites, nanocomposite compositions, and methods of manufacture Dynamic portal creation based on personal usage   Randomly Featured Patents Antibodies to PRO7436 polypeptides Rescue device Starch-degrading benzymes derived from Clacosporium resinae Intra-ocular device with multiple focusing powers/optics Basin Reset relief valve Quick mount truck lift Methods and apparatuses for selectable voltage supply Fast MDCT (modified discrete cosine transform) approximation of a windowed sinusoid Tractor © 2006-2008 PatentGenius.
