  1. 31. Prediction of flue gas properties using artificial intelligence : Application of supervised machine learning by utilization of Near-Infrared Spectroscopy on solid biofuels

    University essay from Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Author : Bashe Abdirahman Hussein; Emran Samimi; [2022]
    Keywords : Artificial Intelligence; Machine learning; Near-Infrared spectroscopy; Solid biofuels; Fuel element; Flue gas composition; CCS;

    Abstract : This degree project studies implementation and comparison of different AI models to predict (1) solid biofuel elements including carbon, hydrogen, nitrogen, and oxygen as well as moisture content, ash content, and higher heating value (HHV) of the fuel and (2) flue gas compositions such as concentration of carbon dioxide, carbon monoxide, nitrogen, nitrogen oxides, and water content using near-infrared spectroscopy and chemometric approaches. The study executes these predictions by simulating the operation of a combined heat and power plant (CHP) that is equipped with carbon capture and storage (CCS). READ MORE

  4. 33. Purification of Volatile Organic Compounds in Channeled Ventilation Pipes at the Sysav Water Treatment Plant for Hazardous Waste

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Erik Wiktorsson; [2022]
    Keywords : VOC; Zeolite; Catalytic combustion; Sysav; Chemical Engineering; Chemistry; Technology and Engineering;

    Abstract : Several channeled emissions at the Sysav water treatment plant for hazardous waste as of December 2021 exceed permitted levels of unknown volatile organic compounds (VOCs) stated in the European Parliament councils’ directives 2010/75/EU. A range of possible treatment methods are briefly discussed before zeolite adsorption, and thermal regeneration followed by catalytic combustion is decided to be the method of greatest feasibility and is the subject of further investigation.

  5. 34. Precipitation behavior of the super austenitic stainless steel SANICRO® 35 and the effect on impact toughness and pitting corrosion resistance

    University essay from KTH/Materialvetenskap

    Author : Shunyi Li; [2022]
    Keywords : Super austenitic stainless steel; solid phase transformation; TTT diagram; impact toughness; critical pitting temperature; TC PRISMA simulation; Superaustenitiskt rostfritt stål; fastfasomvandling; TTT-diagram; slaghållfasthet; kritisk punktfrätningstemperatur; TC PRISMA simulering;

    Abstract : This research extended the knowledge of the solid phase transformation and the resulting influence on impact toughness and pitting corrosion resistance in super austenitic stainless steel (SASS) SANICRO® 35. A time-temperature-transformation diagram (TTT diagram) was assembled by performing isothermal heat treatments in the temperature range of 650-1050 °C for different periods of time, ranging from 5 min to 500 min.

  6. 35. Experimental Evaluation of Time Study for Conventional Case Hardening at Härdservice

    University essay from

    Author : Binnu Kurian Mathew; Vishal Vijayan; [2022]
    Keywords : Case Hardening; Time Study;

    Abstract : Heat treatment is the process of heating metal without allowing it to reach a molten state or melting, it and then cooling it in a controlled manner to choose desired mechanical qualities. Heat treatment aims to make the metal stronger, more malleable, more abrasion resistant, and more ductile. READ MORE
