Abstract

CARVALHO, E. et al. Development of a hydrodynamic model for air-lift reactors. Braz. J. Chem. Eng. [online]. 2000, vol.17, n.4-7, pp.607-616. ISSN 0104-6632.  http://dx.doi.org/10.1590/S0104-66322000000400025.

In this paper, a 1D hydrodynamic model has been developed for gas hold-up and liquid circulation velocity prediction in air-lift reactors. The model is based on momentum balance equations and has been adjusted to experimental data collected on a pilot plant reactor equipped with two types of gas distributors and using water and water/butanol as the liquid phase. Different techniques of signal analysis have also been applied to pressure fluctuations in order to extract information about flow regimes and regime transitions. A good knowledge of the flow pattern is essential to establish adequate correlations for the hydrodynamic model.

Keywords : 1D hydrodynamic model; momentum balance equations; air-lift reactors.
