  1. 1. Development and characterization of multi-streams heat exchangers for liquefaction cycle analysis in the contextof hydrogen mobility

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

    Author : WULLSCHLEGER LÉA; [2023]
    Keywords : Liquefaction cycle; multi-streams heat exchanger; Matlab; PROOSIS; AMESIM; ArianeGroup;

    Abstract : This paper presents the master thesis work done at ArianeGroup on the development and characterization of multi-streams heat exchangers for liquefaction cycle analysis in the context of hydrogen mobility. In 2015, the Paris Agreements aimed at strengthening the global response to the threat of climate change by keeping the temperature rise below 1. READ MORE

  3. 2. Bio-LNG and CO2 liquefaction investment for a biomethane plant with an output of 350 Nm3/h : A techno-economic-environmental analysis

    University essay from Högskolan i Gävle/Energisystem och byggnadsteknik

    Author : Lars-Julian Vernersson; [2022]
    Keywords : Biomethane liquefaction; Carbon dioxide liquefaction; Biogas upgrading; Liquefaction economy; Biomethane life cycle assessment; Biomethane greenhouse gas saving potential; Biomethane emission factor.;

    Abstract : Stricter requirements from the European Union and the German government regarding the utilization of renewable and sustainable fuels for transportation, power, and heat production are currently in effect. This has led to that heavy transportation companies are looking for a more sustainable alternative to liquefied natural gas, such as liquefied biomethane. READ MORE

  4. 3. Continuous Hydrothermal Co-liquefaction of Biomass : An experimental study on the effects of fuel mixing on the composition and yield of biocrude and hydrochar

    University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Author : Simon Fridolfsson; [2022]
    Keywords : HTL; TGA; SEM EDS; Co-liquefaction effects; GROT; Kraft lignin; Microalgae;

    Abstract : An experimental study on the effect of fuel mixing on the products resulting from hydrothermal liquefaction (HTL) was conducted. The feedstocks used were kraft lignin (KL), GROT (GT) and microalgae cultivated in wastewater (MA). Three sets of mixtures were prepared, each containing two types of feedstocks with a 1:1 ratio: KLGT, MAKL, and MAGT. READ MORE

  5. 4. Technoeconomical evaluation of small-scale CO2 liquefaction using Aspen Plus

    University essay from KTH/Kemiteknik

    Author : Maja-Stina Svanberg Frisinger; [2021]
    Keywords : Carbon capture and storage CCS ; carbon dioxide; carbon neutral; production costs; pulp and paper mills; Avskiljning och lagring av koldioxid CCS ; koldioxid; koldioxidneutral; produktionskostnader; massa och pappersbruk;

    Abstract : Syftet med den här studien är att göra en teknoekonomisk utvärdering av processer för förvätskning av CO2 med hjälp av Aspen Plus. Ett flertal förvätskningsprocesser från tidigare studier jämfördes och från dessa valdes två förvätskningsprocesser ut för fortsatta studier och simuleringar. READ MORE

  6. 5. Techno-economic assessment for optimised renewable jet fuel production in Sweden

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

    Author : Jenny Trinh; [2021]
    Keywords : ;

    Abstract : The aviation industry contributes to more than 2% of global human-inducedCO2-emissions, and it is expected to increase to 3% by 2050 as demand for aviation grows. As the industry is still dependent on conventional jet fuel (CJF), one of the key elements to help decarbonise the industry is to transition to renewable jet fuel (RJF). READ MORE
