    Uppsats för yrkesexamina på grundnivå, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Författare :Alexander Luukas; [2022]
    Nyckelord :Optimized steam sootblowing; superheaters; fouling; boiler efficiency; Waste fueled boiler; Overlapping sooting sequence; sotoptimering; ångsotning; överhettare; slaggning; överlappande sotblåsning; avfallspanna; pannverkningsgrad;

    Sammanfattning : The EU waste hierarchy includes energy recovery facilities where waste is used as fuel in combined heat- and powerplants. When waste is incinerated can the thermal energy be used in for example, district heating networks and or electricity generation. LÄS MER

  3. 2. 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

  4. 3. Alkali Circulation in the Blast Furnace - Process Correlations and Counter Measures

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Industriell miljö- och processteknik

    Författare :Joel Carlsson; [2018]
    Nyckelord :Alkali; coke; experimental blast furnace; top gas; mass spectrometry; multivariate analysis;

    Sammanfattning : In blast furnace ironmaking one major challenge is to control and measure the alkalis circulating and accumulating in the blast furnace (BF). Alkali enter the BF with the primary raw material and will form a cycle where it is first reduced to metal at the lower parts forming gas. LÄS MER

  5. 4. Studies of the Impregnation Stagein Kraft Pulping of Hardwood

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Jonas Garemark; [2018]
    Nyckelord :;

    Sammanfattning : In kraft pulping, one of the main issues is the extensive wood losses. With increasing prices ofwoody biomass an incentive towards minimizing the wood losses exists. Amongst the variousprocess steps, the impregnation of wood chips has shown to enhance the cooking by providinga homogeneous distribution of chemicals inside the chips. LÄS MER

  7. 5. Inverkan av impregneringssteget på alkaliförbrukning och delignifieringsgrad vid sulfatkokning

    Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Författare :Erik Nähl; [2015]
    Nyckelord :Kraft cooking; Eucalyptus; Impregnation stage; Pulp technology; Alkali consumption;

    Sammanfattning : The technique to produce pulp has improved and become more complex throughout the years. The purpose of pulping is to liberate the wood fibers and it can be done in two ways, either by chemically or mechanically separating the fibers. LÄS MER
