  1. 1. Improvement of anautomatic networkdrawing algorithm in thecontext of utility networks

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Hyacinthe Ménard; [2024]
    Nyckelord :District Heating Network; Mathematical Optimization; Python; Fjärrvärme; Optimeringslära; Python;

    Sammanfattning : The European Union’s ambitious climate targets necessitate substantial reductions in greenhouse gas emissions, particularly within the heating and cooling sector, which accounts for a significant portion of energy consumption. District Heating and Cooling (DHC) systems emerge as a key solution for decarbonizing this sector by enabling high efficiency heat production and the integration of renewable and carbon-neutral energy sources.

  2. 2. Integrating Waste Heat from Hydrogen Production Into District Heating

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Fawzi Kayali; [2023]
    Nyckelord :Hydrogen; Electrolysis; Waste Heat Recovery; Combined Heat and Power Plant; District Heating; Simulation; Sustainable Heating Systems; Technology and Engineering;

    Sammanfattning : The aim of this research is to explore the feasibility of the integration of waste heat from electrolyzers within a Combined Heat and Power (CHP) plant and district heating (DH) network and suggest a practical setup for integration. With the escalating emphasis on the development of green hydrogen through electrolysis powered by renewable energy, a substantial amount of waste heat is generated, typically left unused. LÄS MER

  3. 3. Integration of a heat recovery system in a Spray Drying Process : Model Simulation Analysis and Economic Feasibility

    Magister-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

    Författare :Marcel Hott Oller; [2023]
    Nyckelord :Spray Drying; Heat pump; Simulation model; heat recovery system;

    Sammanfattning : The spray drying process is widely established in the industry worldwide. However, due to its complexity in predicting variables, the technology is often regarded as a "Black box" process. LÄS MER

  4. 4. Control of carbon dioxide capture from biomass CHP plants : Designing a suitable control system to realize the flexible operation of the CO2 capture system

    Master-uppsats, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Författare :Tanmmay Rout; [2023]
    Nyckelord :Carbon capture; biomass fired combined heat and power plant; MEA based chemical absorption; flue gas; dynamic operation; PI controllers;

    Sammanfattning : This degree project studies the integration of carbon capture system into biomass fired combined heat and power (bio-CHP) plants. The key disturbances from bio-CHP plants include flue gas flow rate, carbon dioxide (CO2) concentration and available heat for the reboiler because the use of versatile biomass and the dynamic operation of CHP plants results in large fluctuations in the properties of flue gas and the heat input for CO2 capture.

  5. 5. Evaluation of Excess Heat Driven Carbon Capture Integrated at a Swedish Pulp Mill

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Frida Nilsson; [2023]
    Nyckelord :CCS; BECCS; pulp and paper industry; pulp mill; excess heat; MEA; HPC; AMP; DMSO; chemical engineering; environmental engineering; Technology and Engineering;

    Sammanfattning : As the atmospheric carbon dioxide keeps increasing, bioenergy with carbon capture and storage (BECCS) is getting increased attention as a measure to reduce the emissions of carbon dioxide. It is especially interesting in Sweden where the extensive paper and pulp industry constitutes point sources of biogenic carbon dioxide. LÄS MER
