Wet Pressing Models to Reduce Energy Consumption in Papermaking

         

摘要

Improved wet pressing reduces the need for drying and consequently energy needed in papermaking.Accordingly,it is desirable to optimize wet pressing,but the process is very complex with many interacting variables.It is therefore desirable to employ a mathematical model that accounts for the major variables to estimate the effects of changes in equipment and operating variables.This paper descibes such a model called the Decreasing Permeability Model (DPM).Mill and pilot plant applications over a wide range of basis weights for paper and paper board are described.
