1. 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

2. Viscosity and boiling point elevation of black liquor from the lignin extraction process and the modification of extracted lignin
Abstract : .... READ MORE

3. Lignin Extraction from Black Liquor - Precipitation, filtration and washing
Abstract : Various process streams in the pulp and/or paper mill contain valuable substances which can be converted into new products, e.g. lignin and xylane. READ MORE

4. Precipitation and separation of lignin from kraft black liquor
Abstract : The separation of lignin from black liquor is an attractive option to consider for pulp mills. In modern pulp mills, lignin extraction offers the opportunity of withdrawing an energy surplus in the form of a solid biofuel. READ MORE

5. 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
