Abstract

<p>The pulp stock washing process following to the Kraft pulp(KP) cooking blow line is consist of a number of washing equipment. This washing line is not only to wash the pulp stock effectively but also to send back the recovered filtrate liquid that contains KP cooking chemical components (expensive sodium compound) and wood lignin components to the following another KP causticizing process. In general, the countercurrent flow washing method has been adopted in the washing process, and to achieve pulp stock washing states well and effectively with less amount of fresh water as small as possible etc. are expected. In this paper, I show a calculation model for a series of KP pulp stock washing line to estimate the chemical component mass balance, and examine the sates' differences when the washing flows are changed around the fresh washing water line, how will be change the chemical recovering states of chemical amount, overall their consistency and losing chemical amounts and so on.</p>
