  1. 1. Biofuels from Kraft Black Liquor : Pilot-Scale Gasification Development and Techno-Economic Evaluation of Industrially Relevant Biofuel Production Pathways

    Author : Yawer Jafri; Erik Furusjö; Ilkka Hannula; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; biofuels; black liquor; pyrolysis oil; gasification; drop-in; energy systems; techno-economic; Energiteknik; Energy Engineering;

    Abstract : Fuel combustion for transport was responsible for 24% of EU-28 greenhouse gas (GHG) emissions in 2016. Member states are expected to ensure that the share of renewable energy in the transport sector is at least 14% by 2030. Some countries, such as Sweden, have more ambitious targets. READ MORE

  2. 2. Black Liquor Scaling Propensity - Experimental Investigation in a Pilot Evaporator

    Author : Mathias Gourdon; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sodium carbonate; fouling; sodium sulphate; black liquor; incrustation; scaling; evaporation; falling film; evaporator; encrustation; kraft black liquor;

    Abstract : Scaling in the recovery cycle of kraft pulp mills has long been recognised as a problem, especially in black liquor evaporators. Most problems are connected with the precipitation of sodium salts. READ MORE

  3. 3. Precipitation and separation of lignin from kraft black liquor

    Author : Fredrik Öhman; Chalmers University of Technology; []
    Keywords : pressing; filtration; washing; lignin; separation; precipitation; black liquor; extraction;

    Abstract : The separation of lignin from black liquor is an attractive option to consider for pulp mills. In modern pulp mills, lignin extraction offers the opportunity of withdrawing an energy surplus in the form of a solid biofuel. READ MORE

  5. 5. Extraction of Lignin from Kraft Cooking Liquor by Ultrafiltration

    Author : Ola Wallberg; Institutionen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lignin; Chemical technology and engineering; cooking liquor; kraft black liquor; Kemiteknik och kemisk teknologi; Ultrafiltration;

    Abstract : Lignin is a potential biofuel which can be extracted from kraft cooking liquor. Lignin can also prove valuable as a speciality chemical. By extracting lignin potential economical revenue can be gained by pulp mills, as well as technical benefits such as easier delignification and bleaching. READ MORE
