  2. 1. Black liquor gasification : experimental stability studies of smelt components and refractory lining

    Author : Mathias Råberg; Dan Boström; Anders Nordin; Honghi Tran; Umeå universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; black liquor gasification; DTA; stability; thermal analysis; thermochemical data; HTM; HT-XRD; metastable; phase diagram; refractory lining; SEM; Chemical energy engineering; Kemisk energiteknik;

    Abstract : Black liquors are presently combusted in recovery boilers where the inorganic cooking chemicals are recovered and the energy in the organic material is converted to steam and electricity. A new technology, developed by Chemrec AB, is black liquor gasification (BLG). READ MORE

  4. 2. Experimental studies of pulverised biomass combustion : Impacts on ash transformations and process temperature

    Author : Daniel Nordgren; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Abstract : Den samlade erfarenhet som finns kring användandet av rena biobränslen för produktion av värme- och kraftvärme kommer till största del från rost- och fluidbäddpannor. Pulvereldningstekniken har traditionellt sett nyttjats mest för kolbränslen, och erfarenheter av rena biobränslen i pulvereldade anläggningar är därför begränsad. READ MORE

  5. 3. Waste Heat Driven Membrane Distillation for Industrial Wastewater Treatment

    Author : Imtisal-e- Noor; Andrew R. Martin; Olli Dahl; Mikel Duke; KTH; []

    Abstract : The European Union has placed a high priority on reaching the goals described in the 2030 Agenda for Sustainable Development. This aim has provided added momentum to member-state environmental regulatory authorities to further tighten the discharge limits of industrial wastewater. READ MORE

  6. 4. Modelling of the pyrolysis of large wood particles

    Author : Michel Bellais; Krister Sjöström; Björn Zethraeus; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; drying; modelling; pyrolysis; shrinkage; wood; Chemical energy engineering; Kemisk energiteknik;

    Abstract : Wood is an interesting alternative to fossil fuels. It is CO2-neutral and widely available. However it is a difficult fuel to handle which features a low energy content. Thus technologies for wood thermal conversion need to be improved. READ MORE

  7. 5. Turbomachinery in Biofuel Production

    Author : Martin Görling; Mats Westermark; Simon Harvey; Bengt Hylander; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bio-Methanol; Biomass; Gasification; Humidification; Hybrid Cycle; SNG; Chemical energy engineering; Kemisk energiteknik;

    Abstract : The aim for this study has been to evaluate the integration potential of turbo-machinery into the production processes of biofuels. The focus has been on bio-fuel produced via biomass gasification; mainly methanol and synthetic natural gas. The research has been divided into two parts; gas and steam turbine applications. READ MORE
