  • Drop-Size Analysis in a Two-Phase Reactive Liquid−Liquid System on a BubbleCap Tray
    Industrial & Engineering Chemistry Research, 2005
    Co-Authors: Devender S Negi, Alexander Rochlitz, Gunter Wozny, Reinhard Schomacker

    Abstract:

    In the present work, the drop-size distribution is investigated in a reactive liquid-liquid system on a BubbleCap Tray. The transesterification reaction between glycerol and methyl oleate is taken as a case of the two-phase liquid-liquid reaction. A microphotographic technique was used to photograph the drops directly in the liquid-liquid dispersion. The drop-size distribution is studied with and without reaction at different gas flow rates with a high dispersed-phase fraction. The drop-size distribution is fitted by normal and log-normal distributions. A weak dependency of the gas velocity on the Sauter mean diameter is found for the nonre-acting system (d 32 G -0.17 ). No significant effect of the gas velocity could be seen for the reacting system.

  • A startup model for simulation of batch distillation starting from a cold state
    Computers & Chemical Engineering, 2003
    Co-Authors: Lin Wang, Gunter Wozny, Pu Li, Shuqing Wang

    Abstract:

    Abstract Batch distillation columns are frequently started up with a different initial reboiler charge. A proper initial state is required for simulation and optimization of such processes, but it has been a non-trivial task to obtain it. In this work, a model to express startup behaviors of batch columns starting from an empty cold state is proposed to address this issue. Each Tray is described beginning with a non-equilibrium phase in which only mass and energy transfer is taking place, to an equilibrium phase in which the vapor–liquid equilibrium is being held. The switching point between these two phases is determined by the Bubble-point temperature at the operating pressure. The equilibrium state is reached Tray by Tray from bottom to top of the column, while the liquid holdup on the Trays is mainly filled in the opposite direction. A difficulty in solving the model equations is that the number of variables of the Trays is not the same when their state switches from a phase to another. Trivial equations are introduced to deal with this problem. g proms is used as the simulation platform. The startup of a three-component batch distillation column is simulated with this model and the results are compared with those from an equilibrium model. The model proposed is verified through experiment on a pilot batch plant with a BubbleCap Tray column to separate a methanol–water mixture.
