  3. 2. Carbon Capture for Biomass Combustion

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Anders Amundsson; [2023]
    Keywords : beccs; ccs; carbon capture; AMP DMSO; amine absorption; heat integration; chemical engineering; environmental engineering; Technology and Engineering;

    Abstract : In order to limit global warming, bioenergy carbon capture and storage (BECCS) technologies are getting increased attention. To meet emission scenarios, an estimated 4000 carbon capture plants are expected to be required by 2030, indicating that progress in carbon capture and storage (CCS) deployment is currently lagging behind expectation.

  4. 3. CFD investigation of a unit cell inside a Plate Heat Exchanger

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Mattias Ly; [2023]
    Keywords : Plate Heat Exchanger; CFD; Computational Fluid Dynamics; LES; Large Eddy Simulation; Periodic; Unit Cell; Technology and Engineering;

    Abstract : A numerical investigation of the unit cell approach has been done to reduce the computational cost for CFD (Computational Fluid Dynamics) of plate heat exchangers (PHE) at Alfa Laval. The reduced cost would enable LES (Large Eddy Simulation) to be done which would give a more detailed and accurate insight into the flow and heat transfer processes of the PHE. READ MORE

  5. 4. Heat recovery from vacuum brazing furnaces

    University essay from Lunds universitet/Avdelningen för Installations- och klimatiseringslära

    Author : Oliver Robertsson; Rasmus Wikman; [2023]
    Keywords : Waste heat; Vacuum furnace; Heat recovery; HVAC; Technology and Engineering;

    Abstract : By partly replacing the use of primary energy sources with waste heat recovery, climate and environmental goals for the future will be closer at hand. This thesis investigates the waste heat potential of Alfa Laval's vacuum brazing furnaces in Ronneby and alternative ways of integrating the furnace's waste heat into the building's HVAC system.
