  • Title: Mixing in liquid-impelled loop reactors.
    Author: Van Sonsbeek HM, Van Der Tuin SP, Tramper J.
    Journal: Biotechnol Bioeng; 1992 Mar 25; 39(7):707-16. PubMed ID: 18601002.
    Abstract:
    The liquid-impelled loop reactor is a new column-type bioreactor. The design of this device is based on the principle of the air-lift loop reactor. In the external-loop configuration used in this work, descending perfluorochemical drops bring about circulation of the continuous aqueous phase. Mixing of this continuous phase is characterized per section of the reactor. Axial-dispersion coefficients for the tube with two-phase flow are determined and correlated with the energy dissipation in the tube. Comparisons with similar systems such as bubble columns and air-lift loop reactors are made. Overall mixing parameters are derived and used for calculation of the number of circulations needed to achieve a certain degree of mixing. The hydrodynamic model from previous work is tested for the reactor configurations of this work. It can be useful to calculate circulation times.
