  1. 11. Modeling self-heating and dry matter loss in large-scale biomass storage

    Master-uppsats, KTH/Kemiteknik

    Författare :Johan Qviström; [2022]
    Nyckelord :Modell; biomass; storage; self-heating; dry matter loss; Modell; biomassa; förvaring; uppvärmning; torrsubstansförlust;

    Sammanfattning : Materialförluster och självuppvärmning är ett vanligt problem vid lagring av biomassa i stor skala. Biomassan som lagras bryts med tiden ned av mikroorganismer och kemiska processer vilket resulterar i en förlust av torrsubstans, ofta kring 1-4% per månad. LÄS MER

  3. 12. Solubility of arsenic in untreated and ZVI-treated contaminated aquifer material

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Oscar R. Davies; [2022]
    Nyckelord :Hjältevad; zerovalent iron; phosphate extraction; Oxalate extraction; Visual MINTEQ; geochemical modelling;

    Sammanfattning : Arsenic (As) is a toxic element to all life and exists in nature both naturally and anthropogenically. Naturally As contaminated soils are formed due to high geogenic background As concentrations which is released when bedrock is eroded. Asia is a continent with a high amount of naturally As contaminated soils and groundwater. LÄS MER

  4. 13. Polymerization of isatin towards polymers for anion exchange membranes and gas separation applications

    Master-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Simone Facchini; [2022]
    Nyckelord :organic chemistry; membranes; isatin; polymers; Chemistry;

    Sammanfattning : In a world where the problem of energy resources, pollution and all aspects related to these issues becomes more and more dominant, a greater commitment is needed in the search for solutions. The goal of this project is to make a contribution to the research and development of new materials to reduce the environmental impact in some fields. LÄS MER

  5. 14. Influence of mixing and heat transfer in process scale-up

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Paula Martín Díaz; [2022]
    Nyckelord :Scale-up; mixing; heat transfer; computational fluid dynamics; process simulation;

    Sammanfattning : Process scale-up studies are, generally, non-linear. This basically means that it is not possible to take a chemical process in the laboratory and bring it to a pilot or production plant by simply increasing the quantities of chemicals and the equipment size proportionally.

  7. 15. LES modelling of spray combustion

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Arvid Åkerblom; [2021]
    Nyckelord :Gas Turbine; CFD; Large Eddy Simulation; Lagrangian Particle Tracking; Chemical Kinetics; Reaction Mechanism; Combustion; OpenFOAM; CHEMKIN; Technology and Engineering;

    Sammanfattning : Computational fluid dynamics is a powerful method for understanding the flow and combustion that occurs inside aircraft engines and will be a key tool in the transition from conventional fossil-based fuel to sustainable alternatives. Because conventional fuels have been more widely researched, an attempt at simulating the combustion of alternative fuels should be preceded by the development of a method that is capable of accurately simulating the combustion of a conventional fuel.
