1. 21. Alternative fuels for shipping : Feasibility study in Singapore

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Beatrice Foscoli; [2020]
   Keywords : ;

   Abstract : This thesis work was performed as a collaboration between the University of Cambridge and the Royal Institute of Technology and was initially intended to be performed as a 5-months internship at the CREATE Centre of Singapore. Unfortunately, due to the COVID-19 pandemic, it could only be done remotely. READ MORE

3. 22. Secondary aerosol formation from dimethyl sulfide - Smog chamber experiments and detailed process modelling

   University essay from Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

   Author : Dana Lüdemann; [2020]
   Keywords : aerosol modelling; atmospheric physics and chemistry; marine aerosols; ADCHAM; aerosol; dimethyl sulfide; Physics and Astronomy;

   Abstract : The aim of this thesis was to investigate the secondary aerosol formation from dimethylsulfide (DMS) using the aerosol dynamics, gas- and particle-phase chemistry kinetic multi-layer model, ADCHAM. The first simulations, concerning the butanol oxidation via hydroxyl radicals (OH), were performed to characterize the UV-light source of the AURA smog chamber (Aarhus university, Denmark), later used for the DMS experiments.

4. 23. Transient Flow Simulations in Exhaust After Treatment Systems

   University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

   Author : John Walder; [2020]
   Keywords : Computational Fluid Dynamics; exhaust after treatment system; ammonia mixing;

   Abstract : The exhaust after treatment system is responsible for removing particulates and contaminants from the exhaust gases. The flow entering the SCR, a catalyst utilizing ammonia to reduce NOx emissions, was studied. The quality and distribution of flow entering the SCR plays an important role in the efficiency of the systems. READ MORE

5. 24. A Numerical Calculation Tool Design for the Performance Assessment of a Bench-Scale Thermochemical Heat Storage System

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : DIYUE WANG; [2020]
   Keywords : Calculation tool; SrCl2-NH3; Performance evaluation; Mass; Energy; Beräkningsverktyg; SrCl2-NH3; Prestandasutvärdering; massa; energi;

   Abstract : Thermochemical heat storage (TCS) is a technology to convert the heat and cold energy into chemical energy, via reversible chemical reactions, to be stored for heating and cooling applications. TCS technology is gaining interest for its very compact energy storage densities offering attractive thermal energy storage (TES) alternatives to decrease energy-related greenhouse gas(GHG) emissions and contribute to sustainable development.

6. 25. Investigation of carbon capture technologies for Sävenäs waste-to-energy plant

   University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Author : Jasmine Andersson; [2020]
   Keywords : CCS; flue gas treatment; waste incineration; energy balance; emission abatement;

   Abstract : Carbon capture technologies have the potential to decarbonize the emissions to air from the heat and power sector and contribute to the necessary greenhouse gas emission mitigation in order to meet the Paris Agreement requirements. The energy requirement and ability to retrofit carbon capture units are crucial to convert existing power plants into more environmental benign processes to meet the Swedish national goal of greenhouse gas neutrality at 2045.
