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

    University dissertation from Umeå : Energiteknik och termisk processkemi

    Author : Mathias Råberg; Umeå universitet.; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; black liquor gasification; DTA; stability; thermal analysis; thermochemical data; HTM; HT-XRD; metastable; phase diagram; refractory lining; SEM; TECHNOLOGY Chemical engineering Chemical process and manufacturing engineering Chemical energy engineering; TEKNIKVETENSKAP Kemiteknik Kemisk process- och produktionsteknik 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

  2. 2. Black liquor gasification burner characteristics and syngas cooling

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Mikael Risberg; Luleå tekniska universitet.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Abstract : Black liquor gasification at high temperature is a promising alternative to the conventional recovery boiler process used in chemical pulp mills today. Compared to a conventional recovery boiler a black liquor gasifier can increase the total energy efficiency of a chemical pulp mill and produce a synthesis gas that can be used for production of motor fuel.

    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

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

    University dissertation from Luleå University of Technology
