Solid liquid stirred tanks are commonly used in the minerals industry for operations like concentration, leaching, adsorption, effluent treatment, etc. Computational Fluid Dynamics (CFD) is increasingly being used to predict the hydrodynamics and performance of these systems. Accounting for the solid-liquid interaction is critical for accurate predictions(More)
A phenomenological model of the mechanisms of lignocellulosic biomass pyrolysis processes a b s t r a c t A comprehensive particle scale model for pyrolysis of biomass has been developed by coupling the reaction mechanisms and transport phenomena. The model, which also accounts for the combined effect of various parameters such as particle shrinkage and(More)
Residence time distribution (RTD) study of solids in a three-phase pilot-scale bubble column photoreactor has been carried out in order to provide data for the development of an artificial neural network model usable for process op-timisation. The experimental data indicated that the RTD of solids was a complex nonlinear function of gas and liquid(More)
