  1. 6. Partial hydrodeoxygenation of a heavy bio-based oil fraction : (A technical feasibility study)

    Master-uppsats, KTH/Kemiteknik

    Författare :Akshay Menon; [2020]
    Nyckelord :Hydrodeoxygenation; Tall oil pitch; oxygen removal; sulphidation; catalyst;

    Sammanfattning : This report is intended to provide the reader with an extensive background information on hydrode oxygenation (HDO) of Tall Oil Pitch (TOP), combined with results from chemical property analyses of the same. Firstly, the importance of hydrogenation and oxygen removal for a biomass-based feed material is highlighted. LÄS MER

  3. 7. Metod för provtagning av svartlut och analys av såpa i svartlut

    Kandidat-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Inger-Johanne Hjalmarson; [2019]
    Nyckelord :Black liquor; centrifuge; sampling; sulphur soap; tall oil; Centrifugering; provtagning; svartlut; såpa; tallolja;

    Sammanfattning : In paper pulp production, many details can be optimized. For optimal separation of soap from black liquor, it is important to know the amount of soap in the black liquor. A project to produce a method for sampling black liquor and a method for measuring how much soap is present in black liquor by centrifugation was done at Södra Cell Mönsterås. LÄS MER

  4. 8. Profitability of cogeneration in a chemical industry

    Magister-uppsats, Högskolan i Gävle/Avdelningen för bygg- energi- och miljöteknik

    Författare :Iñigo Monge Zaratiegui; [2017]
    Nyckelord :Cogeneration; boiler efficiency; Rankine cycle; steam;

    Sammanfattning : A high demand of both electricity and heat exists in Arizona Chemical (a chemical plant dedicated to the distillation of Crude Tall Oil) for production processes. Due to the rising cost of resources and electricity, more and more companies are trying to decrease the energy expenses to increase their competitiveness in a global market, thus increasing their profit.

  5. 9. Bark assortments for tall oil production

    Uppsats för yrkesexamina på avancerad nivå, SLU/Department of Forest Biomaterials and Technology (from 131204)

    Författare :Patrik Isacsson; [2016]
    Nyckelord :tall oil; bark; extractives; lipophilic compounds; CTO; TOFA; TOR; fatty acids; resin acids; rosin; Norway spruce; Scots pine; Picea abies; Pinus sylvestris;

    Sammanfattning : Fatty and resin acids in bark residues from forest industries can be used to produce high-value green chemicals. Of the assortments investigated, the bark of spruce pulpwood held the highest amount of these compounds with an average yield of 0.9 kg per cubic meter of wood. LÄS MER

  7. 10. Resin Profile in a Bleached Kraft Pulp Process

    Kandidat-uppsats, KTH/Fiber- och polymerteknologi
