  • Physical and numerical approximations of reactive distillation dynamics

    Creator:
    Pavarajarn, Varong
    Abstract:
    Two approaches to reduce computational requirements for solving reactive distillation problems have been studied: simplification of the model using physical assumptions and numerical approximation using an orthogonal collocation technique. The results of a full-order model with time dependent stage molar holdups was compared to published steady-state experimental data and was...

  • Roles of gas and solid components in the direct nitridation of silicon

    Creator:
    Pavarajarn, Varong
    Abstract:
    The factors influencing the direct nitridation of silicon, including the effects of the native oxide layer covering the surface of silicon, the effects of hydrogen contained in the nitridation gas and the catalytic effects of metals added to the raw material silicon, were investigated, using a tubular flow reactor and...
