  1. 1. Process and techno-economic analysis of a compact CO2 capture technology

    Master-uppsats, KTH/Energiprocesser

    Författare :Nestor Salvador Palacios; [2023]
    Nyckelord :Carbon capture; CO2 capture cost; compact system; packed column; potassium carbonate; Kolavskiljning; CO2 fångskostnad; kompakt system; packad kolonn; kaliumkarbonat;

    Sammanfattning : Den stora oron för de ökade växthusutsläppen och klimatförändringas effekter har uppmuntrat utvecklingen av åtgärder för att motverka de negativa konsekvenserna. En av de tekniker som har uppmärksammats under de senaste decennierna är kolavskiljningstekniken. LÄS MER

  3. 2. Can iba detect the next compressor failure? : Condition-based monitoring applied to nitrogen compressor – a case study

    Master-uppsats, Högskolan i Gävle/Elektronik

    Författare :Kalle Kurttio; [2023]
    Nyckelord :predictive maintenance; condition-based monitoring; screw compressor; reciprocating compressor; ibaAnalyzer; ibaHD-server;

    Sammanfattning : Production of steel powder is done by atomization of a molten steel stream. Atomization is done by feeding high pressure nitrogen gas through nozzles, creating jets of gas which scatter the molten steel stream into powder. The steel powder falls through the atomization tower whilst it cools and solidifies. LÄS MER

  4. 3. Increased build rate by laser powder bed fusion of SSAB steel powder

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Colin Daly; [2023]
    Nyckelord :Additive manufacturing; Laser powder bed fusion; Build rate; Steel powder;

    Sammanfattning : SSAB has built a pilot gas atomization facility looking to expand their expertise of steel into the metal powder and additive manufacturing industry. Laser powder bed fusion is an additive manufacturing method that melts and fuse metal feedstock powder together layer by layer using a high intensity laser. LÄS MER

  5. 4. Early Stage Design of a Prefilmer at Siemens Energy : Numerical and Experimental Methodology

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Jean-Pierre Hamzo; [2023]
    Nyckelord :CFD; gas-turbine; computational fluid dynamics; atomizer; prefilmer; RANS; LES; multi-phase; experimental; numerical; atomization; spray characteristics; drop breakup; liquid fuels; liquid films;

    Sammanfattning : Design of atomizers for gas-turbine purposes are an important ordeal. The per-formance of the atomizer directly impacts the efficiency of the gas-turbine, andconsequently, the energy extracted from the turbine. Furthermore, the design ofthe atomizer can have an impact on reducing toxic emissions. LÄS MER

  7. 5. Modelling Gas Flow Behaviour in Gas Atomizer

    Master-uppsats, KTH/Materialvetenskap

    Författare :Aravind Senan Vasanthasenan Reji; [2022]
    Nyckelord :Gas atomization; Nozzle; Velocity; Static pressure; Discrete phase model; Gasatomisering; Munstycke; Hastighet; Statiskt tryck; Diskret fasmodell;

    Sammanfattning : Gas atomization is regarded as a reliable method for creating high-quality metal powders from molten metal. The liquid metal is fed into the chamber as a free-falling stream through a nozzle, where it is impinged by high-velocity gas jets, causing degeneration and production of metal droplets, which solidify to create metal powders.
