CFD of Multiphase Flow in High pressure Trickle Bed Reactors: Porous Media Concept
A two-phase Eulerian model, based on porous media concept, describing the flow domain as porous region is presented to estimate the hydrodynamics of two-phase flow in trickle-bed reactors (TBRs) operating at high pressures. The drag forces between phases have been accounted by employing the relative permeability concept (Sàez and Carbonell, 1985). The model has been validated with the different...
متن کاملHigh-Pressure Trickle-Bed Reactors: A Review
A concise review of relevant experimental observations and modeling of high-pressure tricklebed reactors, based on recent studies, is presented. The following topics are considered: flow regime transitions, pressure drop, liquid holdup, gas-liquid interfacial area and mass-transfer coefficient, catalyst wetting efficiency, catalyst dilution with inert fines, and evaluation of tricklebed models ...
متن کاملComputational Flow Modelling of Multiphase Reacting Flow in Trickle-bed Reactors with Applications to the Catalytic Abatement of Liquid Pollutants
The contemporary status of computational flow modelling encourages strongly the application of modern CFD codes on the design and investigation of process equipment and aims to accomplish novel and stringent environmental regulations on the decontamination of high strength wastewaters. The application of CFD is envisaged as a prevailing tool to gain more control in the delivery of reactants or ...
متن کاملCFD Modelling of Trickle-Bed Reactors for Wastewater Treatment
This study aims to incorporate most recent multiphase models in order to investigate the hydrodynamic behaviour of a TBR in terms of pressure drop, liquid holdup and catalyst wetting efficiency. Taking into account transport phenomena such as mass and heat transfer, an Eulerian k-fluid model was developed resulting from the volume averaging of the continuity and momentum equations and solved fo...
متن کاملA Numerical Model for Trickle Bed Reactors
Trickle bed reactors are governed by equations of flow in porous media such as Darcy’s law and the conservation of mass. Our numerical method for solving these equations is based on a total-velocity splitting, sequential formulation which leads to an implicit pressure equation and a semi-implicit mass conservation equation. We use high-resolution finite-difference methods to discretize these eq...
