摘要：

The limitations of the few correlations in the literature for the design of conical spouted beds and the non-validity of these conventional correlations proposed for cylindrical spouted beds have been proven. Consequently, original hydrodynamic correlations for spouting and jet spouting, corresponding to conical contactors, have been proposed for the calculation of the maximum pressure drop and of the pressure drop in stable operational conditions. The hydrodynamic study has been carried out with different geometries of the contactor-inlet system (different angles and diameters of inlet) and with solids of different particle sizes, densities and shape factors, so that the correlations obtained are of general applicability.
