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

    University essay from Lunds universitet/Institutionen för energivetenskaper

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

    Abstract : 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. READ MORE

  3. 2. Trädskador : en studie om att hantera skador på träd i urbana miljöer med inplastning som skötselåtgärd

    University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Author : Andrea-Maria Andersson; Helena Gredvall; [2023]
    Keywords : Kallus; trädvård; övervallning;

    Abstract : Detta arbete har haft som avsikt att undersöka om en riktad skötselåtgärd kan förbättra träds förmåga att övervalla skador. I detta fall rörde det sig om stamskador som uppstått efter en vandaliseringsvåg på Malmö stad och Malmö kyrkogårdsförvaltnings träd under hösten 2020. READ MORE

  4. 3. Recovery of Dialcohol Cellulose using Micro- and Ultrafiltration Processes

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Lina Näslund; Gabriella Petersson; [2023]
    Keywords : Membrane filtration; Ultrafiltration; Microfiltration; Dialcohol cellulose; DAC; Bioplastics; Chemical engineering; Process design; Technology and Engineering;

    Abstract : The waste management and production of plastic play a concerning part in global warming and continues to have a negative effect on the environment. A promising strategy to address this challenge is to develop new sustainable materials, to replace current fossil-based plastics. READ MORE

  5. 4. Control Aid Implementation -Modelling and simulation of triple extruder-

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Karl Langsér; [2023]
    Keywords : Machine Learning; Extruder; Modelling; Simulation; Extreme learning machine; Chemical engineering; Technology and Engineering;

    Abstract : In the production of their High Voltage Direct Current Cables (HVDC) and High Voltage Alternating Current Cables (HVAC), NKT uses triple extruders to create layers of insulation and semi-conduction. A model to predict the effect of extruder inputs on the cable’s insulation and semi-conducting layers has been created and trained to predict the extruder in discrete time. READ MORE

  6. 5. Quality Assurance of Recycled HDPE in the Plastic Packaging Industry

    University essay from Lunds universitet/Innovation

    Author : Tora Abrahamsson; Juliana Kalling; [2023]
    Keywords : Thermoforming; Plastics; Recycling; Packaging Industry; HDPE; Technology and Engineering;

    Abstract : The recycling of plastic has the potential to support circular material use, thus decreasing the need for virgin plastics. However, there is an existing issue with assuring quality of recycled plastic materials, causing finished products to perform with poorer properties and unexpected deviations. READ MORE
