METHOD AND APPARATUS FOR DERIVING INFORMATION FROM LIQUOR OBTAINED IN THE COURSE OF A WOOD DIGESTION REACTION

摘要

Processes and apparatuses for deriving information from liquor obtained in the course of a wood digestion reaction. The information can be used to regulate one or more aspects of the wood digestion reaction either automatically or by communicating the information to a human operator that can take the appropriate process control actions. The information can also be used to regulate processes different from the wood digestion reaction but that depend to at least some extent on the way the wood digestion reaction is being carried out. One example of such other processes is a pulp bleaching process. Another example is a process for burning the liquor from the digester as a source of heat. A further example is a process for fermenting wood sugars in the liquor from the digester to produce alcohol.
