1. 1. 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.

3. 2. The Effect of Temperature Gradients During Intercritical Annealing of Advanced High Strength Steels : Method Development for Experimental Streamlining

   Master-uppsats, KTH/Materialvetenskap

   Författare :Helena Ek Jendrny; [2023]
   Nyckelord :AHSS; Gleeble; Intercritical annealing; Retained austenite; Medium Mn Steel; AHSS; Gleeble; interkritisk glödgning; austenit; Medium Mn stål;

   Sammanfattning : The third-generation advanced high strength steels, AHSS, represent an opportunity for today’s steel development, where lighter materials with maintained strength and toughness are in demand. The unique properties of these materials often stem from a tailored microstructure. LÄS MER

4. 3. Mathematical Modeling and Simulation of Cryogenic Liquid Hydrogen Storage

   Master-uppsats, Lunds universitet/Kemiteknik (CI)

   Författare :Gusten Zandler Andersson; [2023]
   Nyckelord :Modeling; Simulation; Liquid Hydrogen; Storage tank; Modelica; Chemical engineering; Technology and Engineering;

   Sammanfattning : Liquid hydrogen is an attractive alternative to fossil fuels in the aviation industry, but storing it both before and during flights introduces many challenges pertaining to the cryogenic liquid conditions required. Having reliable models to predict the dynamical behavior inside the storage tank is therefore of great interest. LÄS MER

5. 4. Operating procedures and evaluation of a carbon capture pilot plant

   Master-uppsats, Lunds universitet/Kemiteknik (CI)

   Författare :Isac Logeke; [2023]
   Nyckelord :Carbon Capture and Storage; CCS; AMP DMSO; amine absorption; pilot plant; operating procedures; chemical engineering; Chemistry;

   Sammanfattning : The rise in global emissions of carbon dioxide and the need for new technologies to combat climate change has prompted extensive research into carbon capture methods. This master thesis focuses on a novel carbon capture absorption technology, developed at Lund University, that utilizes the amine 2-amino-2-methyl-1-propanol (AMP) in the organic solvent dimethyl sulfoxide (DMSO) to capture CO2.

7. 5. Open-Circuit-Voltage hysteresis measurement and modelling of LiFePO4 Batteries : Master Thesis Report - 2023

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

   Författare :Guillaume Larrat; [2023]
   Nyckelord :Open-Circuit-Voltage OCV Hysteresis - Voltage relaxation - Galvanostatic Intermittent Titration Technique GITT - Hysteresis modelling; Öppenkretsspännings OCV hysteres - Spänningsrelaxation - Galvanostatisk intermittent titreringsteknik GITT - Hysteresmodellering;

   Sammanfattning : In a context of an expected increasing use of Lithium-ion batteries in the transportation sector, Volvo AB is developing its own solutions for large electric vehicles. It is then beneficial to reduce the costs, the energy demand and the raw materials demand by improving the battery systems’ performances. LÄS MER
