  1. 1. Analysis of fatty acids in fatty acid-based herbicides by gas chromatography

    University essay from Lunds universitet/Kemiska institutionen

    Author : Mohamad Abd Elwadood; [2023]
    Keywords : Analytical Chemistry; Fatty Acids; Gas Chromatography; Green Herbicides; Retention Index; Flame Ionization Detector; Mass Spectrometry; Supercritical Carbon Dioxide Extraction.; Chemistry;

    Abstract : Fatty acids-based herbicides are considered to be a green alternative to synthesized weed control products. However, the environmentally sustainable effect of those herbicides needs more investigation to be confirmed. READ MORE

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

    University essay from Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

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

    Abstract : 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.

  4. 3. Biobased iron pellet production : Assessment of the availability and sustainability of biomass as fuel for iron ore pellet production in LKAB

    University essay from Mittuniversitetet/Institutionen för naturvetenskap, design och hållbar utveckling (2023-)

    Author : Magnus Kemi; [2023]
    Keywords : bio-energy; biomass; coal; greenhouse gas emissions; industrial residues; LCA; LKAB; logging residues; iron ore; pellets; sinters; willow; sustainability;

    Abstract : Iron production accounts for substantial shares of global coal use and GHG emissions. LKAB is Europe’s largest iron company and Sweden’s fourth-largest emitter of GHGs. To reduce its emissions, LKAB might implement biomass in iron ore pelletisation. READ MORE

  5. 4. Assessment of the energetic feasibility of a novel CHP biorefinery concept

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Ângelo Miguel Mendes Ferreira; [2023]
    Keywords : biorefinery; bioenergy; biomimicry; combined heat and power; Earth Power Lodge; Technology and Engineering;

    Abstract : This study investigates the potential for energetic self-reliance in an integrated biore- finery, the Earth Power Lodge (EPL), which aims to convert waste into valuable by- products through bio- and thermochemical conversion processes. The primary questions addressed include assessing the necessity of external propane to sustain the pyrolysis process and the net energy output of the ThermoChemical Reactor (TCR) process when fractional distillation is applied to the resulting bio-oils.

  6. 5. Greenhouse gas emissions and energy efficiency of various renewable energy pathways in the truck industry : An LCA and energy efficiency analysis on fuel production for and manufacturing of 40 tonne heavy trucks in Sweden

    University essay from Linköpings universitet/Institutionen för tema; Linköpings universitet/Filosofiska fakulteten

    Author : Jacob Axell; [2023]
    Keywords : Hydrogen; Sweden; 40-tonne haulage truck; LCA; Wind energy; Bio fuel; Energy efficiency; CO2 emissions;

    Abstract : This study focuses on assessing the greenhouse gas emissions and energy efficiency of 40-tonne haulage trucks in fuel production and manufacturing in a Swedish context. The aim was to provide accurate greenhouse gas accounting and evaluate the contribution to mitigating climate change. READ MORE
