  1. 1. Modelling the chemical recycling of plastic waste via pyrolysis and analysing integration with existing refinery infrastructure

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Simon Dahl; [2023]
    Keywords : Pyrolysis; Recycling; Integration; Modelling; Simulation; Techno-economic; Plastic; Chemical engineering; Technology and Engineering;

    Abstract : Current plastic management is unsustainable as large amounts of plastic end up landfilled or in the ocean, necessitating an expansion of waste management infrastructure. Pyrolysis is a viable chemical recycling option, and in this report a pyrolysis model is constructed in Aspen Plus. READ MORE

  3. 2. Tribolysis : – Reaction of Aromatic Halides for Potential Dehalogenation

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Oluwaseunnla P. Adelusi; [2022]
    Keywords : Tribolysis; Tribology; Mechanochemical Processing; Dehalogenation; Dechlorination; Remediation; Persistent Organic Pollutants; POPs; Polychlorinated biphenyls; PCBs; Dichlorotoluene ;

    Abstract : Out of the 17 Sustainable Development Goals (SDGs) adopted by the United Nations in 2015, chemicals and waste management are obtainable under six. Improper and unsafe disposal of toxic chemicals into the environment affects life below water (SDG 14), human health and well-being (SDG 7), and clean water and sanitation (SDG 6). READ MORE

  4. 3. Evaluation of stimulated reductivedechlorination in situ of chlorinatedsolvents at a site in Huddinge : using principal component analysis, partialleast square regression and degradation

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Karin Ljungberg; [2018]
    Keywords : Reductive dechlorination; DNAPL; stimulated bioremediation; chlorinated solvents; Reduktiv deklorering; DNAPLS; stimulerad biologisk behandling; klorerade lösningsmedel;

    Abstract : The method of using stimulated reductive dechlorination when remediating sites contaminated with chlorinated solvents is not unusual, but not many studies have been done on the overall process outside of a controlled environment. In order to investigate the process, principal component analysis (PCA) and partial least square (PLS) regression was used to identify the most important parameters for the degradation of the chlorinated solvents.

  5. 4. A study of dechlorination of organic matter in forest soil using 36Cl as a tracer

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

    Author : Elias Broman; Maria Hägglund; [2011]
    Keywords : Chlorine; Dechlorination; 36Cl; forest soil; organic matter; carbon cycle;

    Abstract : During the Fukushima Daiichi power plant incident sea water was used in an attempt to cool reactor Unit 3. Since sea water contains an excessive amount of chloride, 36Cl has likely been formed and spread in the environment. READ MORE

  6. 5. Iron material for the remediation of DNAPL-polluted groundwater

    University essay from KTH/Mark- och vattenteknik

    Author : Jens Rodenhäuser; [2003]
    Keywords : chlorinated ethylene; iron; reductive dechlorination; groundwater; batch experiments; column experiment; ;

    Abstract : Tetrachloroethylene and its daughter-products represent a group of contaminations which are frequently found at sites with industrial activities, such as metal processing, electrotechnical and pharmaceutical industries as well as dry cleaning of clothing and the production of colours, paints and laquers. Due to their toxicity and persistence under natural conditions "denser-than-water" non aqueous phase liquids are substantial threats to the subsurface environment as well as the surface ecosystems including human beings.
