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...

Reaction kinetic study and determination of controlling resistances during alkaline sulfite/anthraquinone pulping

Creator:: Medhora, Hiraz Kekobad
Abstract:: A survey of the pulping literature indicated that although the kinetics of the Kraft Pulping process has been studied in detail , very few studies have been reported for Alkaline Sulfite / Anthraquinone (ASAQ) pulping process. There is no existing rate model for this pulping process. Hence, the objectives of...

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...

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 proposed model to predict population in relatively rural areas experiencing rapid economic development

Creator:: Clark, Jerry E., 1949-
Abstract:: In this research a model is developed to predict population for relatively rural areas experiencing rapid economic development. Of the many ways to predict population size, in this research a "demographic-economic" model is chosen for use. The economic variables which aid in projecting population are total employment, and net changes...

Local economic impacts of changes in the availability of public timber

Creator:: Eppley, Linda M.
Abstract:: For many resource-based communities throughout Oregon the timber industry plays an important role. In many of these areas, federal land holdings comprise a large proportion of the area's land holdings. Management decisions regarding resource use on the National Forest lands can have a major influence on the stability of local...
