2. Thermodynamic modelling of black liquor-related solutions. Pitzer method for estimating activities, solubilities and boiling point rise
Abstract : Black liquor is considered as being one of the most important process streams as far as the design and optimization of kraft pulp mills are concerned. Many methods have been developed in order to describe and, possibly, predict its physico-chemical properties. Most of them are, however, empirical methods that are difficult to generalize. READ MORE

3. Extraction of Metal Values : Thermodynamics of Electrolyte Solutions and Molten Salts Extraction Process
Abstract : Over the past centuries, a number of process routes for extraction of metal values from an ore or other resources have been developed. These can generally be classifiedinto pyrometallurgical, hydrometallurgical or electrometallurgical routes. READ MORE

4. Lignin Extraction from Black Liquor - Properties of the Liquors and Sulphur Content in the Lignin
Abstract : Kraft lignin isolated by precipitation can be considered as being a valuable renewable source of energy and material. Removing lignin from black liquor is also advantageous as it decreases the load on the recovery boiler, which is usually the limiting factor in the production of kraft pulp. READ MORE

5. Model for activity coefficients and solubilities of Na2CO3 and Na2SO4 in high-temperature solutions
Abstract : Scaling of sodium sulfate and sodium carbonate double salts has long been recognized as a problem in the black liquor evaporation process. These salts are abundant in black liquor and often tend to precipitate on heat transfer areas, thereby significantly decreasing the heat transfer efficiency. READ MORE
