A method for improving the waermeoekonomie during cooking of lignocellulosic material in discontinuous popping marks

摘要

A method for improving heat economy in the batchwise digestion of lignocellulosic material especially when using a batch digester with a digestion or cooking liquor in which the digestion or cooking chemicals are dissolved, such as in sulphate, sulphite, bisulphite, oxygen, peroxide and ammonium hydroxide digestion processes, and also in the manufacture of high yield semichemical pulps.
