Black liquor-properties

← Previous Next →

Black liquor – properties General approach The spent liquors from chemical pulping contain varying amounts of organic compounds derived from all wood constituents (cellulose, hemicelluloses, lignin and extractives).1 The nature and amount of these compounds depend on the feedstock material used for the pulp production as well as on the pulping method applied. It is
