Abstract
The aim of the present work was to study the fractionation of Eucalyptus gl obulus wood into pulp and by-products by alcohol-water pulping. Under the c ooking conditions employed low lignin content pulp and a high yield of by-p roducts were attained. The laboratory-scale alcohol and by-products recover y system studied consisted of three stages: black liquor flashing, lignin p recipitation from black liquor, and distillation of precipitation mother li quor. The mass balance for the process enabled the amount of pulp and by-pr oducts produced and the consumption of chemicals to be estimated. (C) 1999 Society of Chemical Industry.
