  1. 6. Critical hydraulic gradients in tailings dams : comparison to natural analogies

    Författare :Isabel Jantzer; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Sammanfattning : The increasing demand of metals and minerals has made it economical for the mining industry to mine low-grade deposits, which results in immense quantities of by-products. In fact, such by-products, i.e. tailings, are the largest waste volumes produced on earth. LÄS MER

  4. 8. Influence of the electrolyte on the electrode reactions in the chlorate process

    Författare :Linda Nylén; Göran Lindbergh; Ann Cornell; Mårten Behm; Geoeff H Kelsall; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chlorate; chloride oxidation; critical anode potential; chromate; DSA; hydrogen evolution; iron; mass transport; oxygen evolution; REM; RDE; steel; Electrochemistry; Elektrokemi;

    Sammanfattning : The chlorate process is very energy intensive and a major part of the production costs are for electrical energy. Since the electricity prices are constantly increasing and may also vary periodically, the chlorate plants may be forced to adjust their production rate to the price at each moment in order to minimise their costs.

  5. 9. Quality Assurance of Time Critical Data Using Adaptive Data Delivery Mechanisms in Smart Grids

    Författare :Yiming Wu; Lars Nordström; Chen-Ching Liu; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; time critical data quality; adaptive mechanisms; quality assurance; Smart Grid; information resiliency; data accuracy; end-to-end latency; cyber-security; substation automation; power system communication; Electrical Engineering; Elektro- och systemteknik; Industrial Information and Control Systems; Industriella informations- och styrsystem;

    Sammanfattning : Smart grids are proposed to integrate renewable energy and to improve the efficiency of power system operation. The challenges of integrating renewable energy are the inherent fluctuations of generation which are difficult to predict which may lead to challenges to the safe operation of power systems. LÄS MER
