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...

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...

Effects of caustic addition on black liquor rheology and thermal characteristics

Creator:: Euhus, Daniel D.
Abstract:: An important by-product of the kraft pulping process, black liquor is currently used in most pulp mills to produce steam in a recovery boiler. Two important black liquor characteristics are viscosity and burning (firing) characteristics, which determine the operating efficiency of the recovery boiler. Kraft black liquor is a complicated...

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...

Formation of NO during pyrolysis combustion of Kraft black liquor / by Rungsun Pianpucktr

Creator:: Pianpucktr, Rungsun
Abstract:: Nitrogen evolution during black liquor pyrolysis and black liquor combustion were studied using a laminar entrained-flow reactor. The experimental conditions were 700-1100°C and 0.3-2.2 seconds residence time. The pyrolysis experiments were performed in a pure nitrogen atmosphere. The oxygen concentrations during the combustion of black liquor experiments were 4 and...
