  1. 1. Characterization of Raw Materials for Salt Extraction from Lake Katwe, Uganda

    Författare :Hillary Kasedde; Stefan Jonsson; Baohua Zhu; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lake Katwe; salt extraction; brine; evaporites; characterization; PHREEQC;

    Sammanfattning : Uganda is well endowed with economic quantities of salt evident in the interstitial brines and evaporite deposits of Lake Katwe, a closed saline lake located in the western branch of the great East African rift valley. Currently, rudimentally methods of salt mining based on solar evaporation of brine continue to be used for salt extraction at the lake. LÄS MER

  3. 2. Towards the Improvement of Salt Extraction from Lake Katwe Raw Materials in Uganda

    Författare :Hillary Kasedde; Pär Jönsson; Anders Tilliander; Eric Forssberg; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lake Katwe; salt extraction; brine; evaporites; saltpan; characterization; evaporation - crystallization; solubility; Pitzer ’s ion - interaction model; PHREEQC software; dissolution kinetics; Avrami model.;

    Sammanfattning : Uganda is well endowed with economic quantities of mineral salts present in the interstitial brines and evaporite deposits of Lake Katwe, a closed (endorheic) saline lake located in the western branch of the great East African rift valley. Currently, rudimentally and artisanal methods continue to be used for salt extraction from the lake raw materials. LÄS MER

  4. 3. Taking stock of large-scale lithium-ion battery production using life cycle assessment

    Författare :Mudit Chordia; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Brine; Spodumene; Lithium-ion battery; Lithium; Life cycle assessment; Giga-factory; Upscaling;

    Sammanfattning : Battery electric vehicles are being increasingly favored as an alternative to internal combustion engine vehicles (ICEVs). This is mainly due to their lower environmental impact when compared to ICEVs over the vehicle’s lifetime. LÄS MER

  5. 4. Dielectric Properties of Liquid-Impregnated Porous Solids

    Författare :Bo Nettelblad; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fluid-solid interface; porous microstructure; temperature; ion-containing liquid; transport properties of porous media; brine; salinity; electric conduction; models of composite media; interface phenomena; dielectric relaxation; rock;

    Sammanfattning : Dielectric spectroscopy is a versatile tool that can often be used as a non-destructive, indirect way of measuring other important properties (such as content of crude oil or degree of curing of a resin). The dielectric properties of materials are thus of interest in several circumstances and not only for materials used for electrical purposes (such as electrical insulation). LÄS MER
