摘要：
The aim of the present work is to study the fractionation of Eucalyptus globulus wood into pulp and byproducts by alcohol-water pulping. Under the cooking conditions employed high purity cellulose and high byproducts yield were attained. The alcohol and by-products recovery system proposed consists of three stages: black liquor flashing, lignin precipitation, and mother liquor distillation. The mass balance for the process allowed to determine the amount of pulp and by-products produced and the chemicals consumption.
