    Influence of crystal size on the rate of contact nucleation in stirred-tank crystallizers (1974)

    Notes: The purpose of this study was to investigate the influence of seed crystal size on the rate of nucleation in batch stirred-tank crystallizers. Experimental results confirm the existence of such an effect. Nucleation rate data are correlated with a second-order polynomial in seed crystal size; coefficients of the correlation are functions of the solute-solvent system, crystallizer geometry, and mixing conditions. The empirical correlation is incorporated into a population balance model for determining the nucleation rate in multi-seed crystallizers. The observed results are explained in terms of variations in impact energy, circulation frequency, and target efficiency.

    Notes: The flow and processing behavior of commercial plastics is determined not only by the characteristics of the base resin but also by the presence of additives of various kinds. In this study the influence of a number of additives on the rheological behavior of molten ABS was investigated using a capillary extrusion rheometer and a Weissenberg rheogoniometer. The additives studied included molding lubricants, rubber impact modifiers, flame-retardant additives, and residual unreacted components remaining from the polymerization process. The mechanisms by which these species affect flow characteristics are described.

    Notes: Measurements of iodine dissolution rates in supercritical carbon dioxide and other supercritical fluids show when the iodine flux in these systems can be made fast. For these systems, the dominant factor in achieving this fast flux is the solubility; increases in diffusion coefficient have less effect. An approximate guide for estimating these fluxes is developed and compared with the experimental results.

    Notes: Part II of the review paper covers the self-diffusion theories and their comparison with experimental results. This is followed by a review of empirical and semi-empirical predictive equations of mutual and self-diffusion coefficients. Recent developments in experimental techniques for measuring liquid diffusivities are discussed in the last section. A supplement of experimental diffusion data since 1956 is available.

    On the oxidation of fuel nitrogen in a diffusion flame (1974)
    Hoboken, NJ : Wiley-Blackwell

    Notes: The kinetic mechanisms of fuel nitrogen conversion to NO and N2 in a diffusion flame were investigated. A simple model of a diffusion flame in which the reaction zone has a finite thickness was developed. The purpose of this model was to allow the testing of complex kinetic mechanisms of pollutant formation under conditions where the fuel and oxidant feed rates are controlled by diffusion. A simple kinetic mechanism in which fuel nitrogen was simulated by nitrogen atoms showed the correct functional dependence of nitric oxide emissions on fuel nitrogen content. The model also predicts a significant effect of combustion intensity and temperature on fuel nitrogen conversion. For the hydrogen air diffusion flame the Zeldovich reaction mechanism could account for the production of N2 as well as NO.

    Optimal temperature policy for reversible reactions with deactivation: Applied to enzyme reactors (1974)
    Hoboken, NJ : Wiley-Blackwell

    Notes: The optimal temperature policy which will maximize the final catalyst activity that gives a fixed conversion of reactants in a specified time for batch operation was determined by the formulation of a calculus of variations problem following the technique of Szepé and Levenspiel (1968). The method was applied to the general case of first-order reversible reactions which occur in the presence of catalysts deactivating by an irreversible first-order mechanism. To reduce trial and error estimations and circumvent numerical instabilities, the two-point boundary value variational problem was reformulated in terms of an initial value problem with a parameter which includes the initial value of temperature. This initial value problem was solved by a regression technique.These techniques were applied to the industrially important enzymatic reaction of the isomerization of D-glucose to D-fructose catalyzed by glucose isomerase in solution. Kinetic and deactivation data are available for this endothermic reaction which obeys first-order reversible kinetics and for the isomerase denaturation which appears to be first order. The optimal temperature operational policy as stated above maximized final enzyme activity such that 10% less denaturation of glucose isomerase occurred when compared to final isomerase activity yielding the same conversion for the same reaction time when the reactor is operated at the optimal isothermal temperature.
