Modeling of sulfate reduction in an entrained-flow black liquor gasifier

Creator:: Jivakanun, Narongsak
Abstract:: Black liquor gasification is one of the promising alternatives to eliminate the drawbacks of the conventional recovery unit of the kraft process. A numerical model has been developed to simulate an industrial pilot scale entrained-flow gasifier currently operating at Tampere, Finland. The objective of the model is to investigate the...

Investigation of the fundamentals of fluorescent behavior of kraft-anthraquinone pulping liquors

Creator:: Perfecto Segoviano, Ignacio
Abstract:: The kraft and kraft-anthraquinone pulping processes were used for pulping Douglas-fir chips at 170°C, 180°C and 190°C temperatures. Anthraquinone was added to the pulping liquor at two levels, 0.1% and 0.2% based on wood, to study its effect on pulp delignification at the three temperatures. The fluorescent behaviors of kraft...

Deposition of sub-micron and micron-sized particles from combustion of black liquor

Creator:: Sinquefield, Scott Alan
Abstract:: Black liquor recovery boilers experience significant fire-side fouling problems due to the deposition of entrained particulate matter. Increased understanding of the mechanisms by which particles deposit on these surfaces will lead to more effective management of the resultant problems. There is some evidence which suggests that the sub-micron fraction of...

Solubility of aluminosilicates in kraft green and white liquors

Creator:: Wannenmacher, P. Nick
Abstract:: The increasing occurrence of aluminosilicate caused complications in krafi pulp mills can be attributed to the closing of purge points and the expanded use of contaminated feedstocks and recycled fiber sources. An active purge of aluminum and silicon from the chemical recovery cycle must be undertaken in order to maintain...

The effect of temperature and residence time on the distribution of carbon, sulfur, and nitrogen between gaseous and condensed phase products from low temperature pyrolysis of kraft black liquor

Creator:: Phimolmas, Varut
Abstract:: Laminar entrained flow reactor (LEFR) was used to determine the effect of temperature and residence time on the distribution of carbon, sulfur and nitrogen between gaseous and condensed phase products from low temperature pyrolysis of kraft black liquor. The operating furnace temperatures were between 400°C-600°C where the effect of condensable...
