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...

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...

A study of liquor side fouling in sulfite spent liquor evaporators

Creator:: Yoon, Woon-young
Abstract:: The effects of possible operating variables such as flow rate, surface temperature, bulk temperature, solids contents, sulfate addition and pH on the fouling of sulfite spent evaporators were studied. The study pointed out that the Ca⁺⁺ concentration difference between heated surface and bulk is the most important factor for fouling...

Sintering of fume deposits in kraft recovery boilers

Creator:: Techakijkajorn, Udom
Abstract:: Fume, sub-micron aerosal particles in the combustion gases, have been identified as a cause of extensive plugging and fouling in the heat transfer section of a kraft recovery boiler in kraft pulp mills. After the deposition on the heat transfer surface, fume deposits will undergo the sintering process which causes...

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...

An investigation of the metaborate monomer and trimer ions in alkali halide crystals

Creator:: Becker, Charles Ransford
Abstract:: The infrared spectra of the metaborate monomer and trimer ions in NaC1, KC1, and KBr were studied. These spectra contain bands due to the trimer in solid solution, in a second phase of the appropriate potassium or sodium salt, and perhaps on adjacent lattice sites. Furthermore, complex equilibria exist between...
