Pulping Process - an overview | ScienceDirect Topics

Young (1992) describes a 450 ton/day mill in Germany using the organocell solvent pulping process. The mill uses a single-stage process with 25%–30% methanol as the solvent to pulp spruce. The alkali charge is 125 g/L with a liquor-to-wood ratio of 4.2:1. AQ, 0.1% on wood, is also used. The cooking temperature is about 160°C (320°F).
