11. Precipitation and separation of lignin from kraft black liquor
Sammanfattning : .... LÄS MER
12. Synthesis gas from black liquor : trace components and methanol synthesis
Sammanfattning : The common European Energy and Climate policy states that in 2020 the share of biofuels for inland transports should be 10 %. Such a stipulation calls for a commercially sustainable biofuel production. LÄS MER
13. Entrained flow black liquor gasification : detailed experiments and mathematical modelling
Sammanfattning : Black liquor, a by-product from the Kraft pulping process is a highly viscous fluid consisting of approximately 30% water, 30 % alkali salts and 40 % combustible material. The alkali salts originating from the pulp making process need to be recovered in order for the pulp mill to be economical and to satisfy environmental regulation. LÄS MER
14. Heat Transfer and Hydrodynamics in Falling Film Evaporation of Black Liquor
Sammanfattning : The evaporation plant is one of the major steam consumers in kraft pulp mills, which are the dominant type of chemical pulp mill in Sweden. Previous studies have shown potential to decrease the live steam demand for the pulp process, e.g. LÄS MER
15. Heat transfer in falling film evaporation of black liquor - Experiments and theory
Sammanfattning : Pulp and paper industry uses a large part of the total amount of energy in industry in Sweden. The evaporation plant has the major energy demand in the kraft pulp mill, which is the dominant type of chemical pulp mill. Previous studies have shown potential to decrease the live steam demand for the pulp process, e.g. LÄS MER
