1. Pressure and Solidosity Profiles in Cake Filtration
Sammanfattning : Filtration is an important unit operation in theseparation of liquids from solids. The aim of this work was toinvestigate filtration properties of lignin sludge obtained in theproduction of fuel ethanol from spruce wood. LÄS MER
2. On the local properties of compressible filter cakes
Sammanfattning : Filtration as a means of separating solids from liquids is an important unit operation employed in a range of different industrial sectors, of which the forest products, mineral, chemical process and pharmaceutical industries are but a few. Accurate and applicable models for the filtration unit operation are imperative if industrial filtration equipment is to be designed correctly. LÄS MER
3. On the local filtration properties during cake filtration: Studies on LignoBoost lignin and the influence of ionic strength
Sammanfattning : The Kraft pulping technology has been thoughtfullyinvestigated and developed over the pasthundred years and more; it is currently the mostcommonly-used method ofpulping in the world. Anew and promising opportunity for Kraft pulp millswould be to take a step towards becomingbiorefineries by implementing technologies ableto extract and convert the organic by-products,such as lignin, into a wide rangeof value-added products and chemicals. LÄS MER
4. On the Local Filtration Properties of LignoBoost lignin: Studies of the influence of xylan and ionic strength
Sammanfattning : Kraft pulping technology is currently the most commonly-used method for producing paper pulp from wood. A new and promising opportunity for Kraft pulp mills is to take a step towards becoming biorefineries by implementing technologies able to extract and convert the organic by-products, such as lignin, into a wide range of value-added products and chemicals.
