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...

Liquor to liquor differences and the effects of liquor feed rate on the distribution of condensed phase combustion products of kraft black liquor solids burned in a laminar entrained-flow reactor

Creator:: Train, Ron
Abstract:: Combustion properties of kraft black liquor solids were studied using a laminar entrained flow reactor. The tendency of black liquors to release fume (compounds containing Na⁺, K⁺, Cl⁻, SO₄²⁻, SO₃²⁻, S₂0₃²⁻ and C0₃²⁻) during combustion were observed at 1000°C. Black liquor solids with a size fraction of 63 to 100...

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...

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...
