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...

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...

Mechanism and equilibrium modeling of aluminosilicate scaling in alkaline media

Creator:: Gasteiger, Hubert A.
Abstract:: Problems with aluminosilicate scales in pulp and paper recycle streams create an interest in the formation mechanism and the chemical equilibrium of aluminosilicates. Evaluating solubility data from a system containing Na⁺ CI⁻, and OH⁻ ions as well as aluminium and silicon compounds, allowed to elucidate the characteristics of the aluminosilicate...

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...

β-lactoglubin adsorption equilibrium and kinetics at silanized silica surfaces

Creator:: Krisdhasima, Viwat
Abstract:: The adsorption equilibrium and kinetic behavior exhibited by β-lactoglobulin at silanized silicon surfaces of varying hydrophobicity were examined using ellipsometry. Adsorption equilibrium results were used to construct adsorption isotherms; the adsorbed mass of β-lactoglobulin was observed to increase with increasing surface hydrophobicity, within a defined range of hydrophobicity. Adsorption kinetics...

A computer program to solve aqueous inorganic equilibrium systems using Pitzer's method to determine activity coefficients

Creator:: Kelly, Barry
Abstract:: Chemical equilibrium is a major factor in many natural and industrial systems. The ability to predict ionic equilibrium is extremely valuable in industry in solving problems without the costs involved in full scale experiments. An example of an application in the pulp and paper industry is the prediction of non-process...

The cloud point composition and flory-huggins interaction parameters of polyethylene glycol and sodium lignin sulfonate in water-ethanol mixtures

Creator:: Luh, Song-ping
Abstract:: In designing a solubility based separation process for solvent recovery of an organosolv pulping process, the phase behavior of polymeric lignin molecules in alcohol - water mixed solvent should be known. In this study, sodium lignin sulfonates (NaLS) samples were fractionated into three different molecular weight fractions using a partial...
