Reducing aox by increasing oxidation potential in the first caustic extraction stage, TAPPI Journal December 2024
Authors: Peter W. Hart and Jeffrey S. Hsieh | Tappi J. 74(11): 117(1991) - ABSTRACT: An increase in the standard oxidation potential of the reinforcing agent in the first caustic extraction stage will reduce the amount of AOX in the stage's effluent. A chlorinated broumstock pulp was treated alternatively in a basic caustic extraction (E) stage, an oxygen-reinforced caustic extraction (EO) stage, and an extraction stage reinforced with oxygen and peroxide (EOP). An AOX reduction of up to 30% was obtained in the effluent from the peroxide-reinforced extraction stage. In addition to the brownstock work, using two different model lignin compounds, we ran tests using oxyen, potassium permanganate, hydrogen peroxide with oxygen, and ozone with oxygen-reinforced caustic stages. In all cases, increasing the oxidation potential of the reinforcing agent decreased the amount of AOX detected in the effluent.
