The scale-up method for three-phase fluidized beds hydrodynamics proposed by Safoniuk et al. [M. Safoniuk, J.R. Grace, L. Hackman, C.A. McKnight, Chem. Eng. Sci. 54 (1999) 4961], based upon the principles of dynamic similitude, was tested matching several systems operated at high pressure with model systems operated at atmospheric pressure. Experiments were carried out to test this technique by comparing...
Experiments were performed to study the hydrodynamic characteristics of ebullate-bed systems operated under conditions of high pressure and temperature. The effects of these variables on bed porosity and the liquid minimum fluidization velocity were determined and a correlation has been proposed as a criteria for determining flow regime transitions between the dispersed and coalesced bubble flow regimes...
