1. New Methods for the Determination of Sorption Capacities and Sorption-Related Properties of Intact Rock
Sammanfattning : .... LÄS MER
2. Mercury and dioxins in a MercOx-scrubber
Sammanfattning : The removal of mercury and the absorption of dioxins in an acid wet scrubber have been studied in industrial scale. Hydrogen peroxide is added as an oxidizing agent to the scrubber liquid with the purpose to remove SO2 and enhance the removal of mercury. LÄS MER
3. Solute transport through fractured rocks : the influence of geological heterogeneities and stagnant water zones
Sammanfattning : To describe reactive solute transport and retardation through fractured rocks, three models are developed in the study with different focuses on the physical processes involved and different simplifications of the basic building block of the heterogeneous rock domain. The first model evaluates the effects of the heterogeneity of the rock matrix and the stagnant water zones in part of the fracture plane. LÄS MER
4. Solute transport in fractured rocks : Analysis of analytical solutions and determination of transport parameters
Sammanfattning : In order to facilitate the assessment of the safety and function of deep geological repositories for radioactive waste, several models have been developed to describe water flow and transport of solutes in fractured crystalline rock. The rock around the repository is described and modelled as a network of water-bearing fractures. LÄS MER
5. An Analytical Solution Applied to Heat and Mass Transfer in a Vibrated Fluidised Bed Dryer
Sammanfattning : A mathematical model for the drying of particulate solids in a continuous vibrated fluidised bed dryer was developed and applied to the drying of grain wetted with a single liquid and porous particles containing multicomponent liquid mixtures. Simple equipment and material models were applied to describe the process. LÄS MER
