Abstract

SAQ® has been used as a cooking additive in many kraft pulp (KP) mills. This process is known as “Quinone Cooking”. In order to establish a convenient method for estimation of KP yield variation by SAQ addition in pulp mill, analysis of black liquor is investigated.<BR>The yield variations by SAQ addition were compared between analysis of black liquor and actual measurement of pulp weight using the laboratory test sample. This result that estimated the variation of pulp yield was in agreement with the calculated value by actual measurement of pulp.<BR>Mill scale trials were conducted to examine the effect of SAQ. Black liquor samples were used the extracted liquor from a digester. As a result, the increases of pulp yield were observed by analysis of black liquor in all trials.
