Flow Mapping of Gas-Solid Riser

Abstract

Gas-Solid Risers Are Extensively Used in Many Industrial Processes for Gas-Solid Reactions (Coal Combustion and Gasification, Etc.) and for Catalytic Gas Phase Reactions (Fluid Catalytic Cracking, Butane Oxidation to Maleic Anhydride, Etc.). Risers Pose Considerable Challenges Because It is Not Yet Possible to Produce Ab Initio Predictions of their Complex Fluid Dynamics, Which Impairs Reactor Modeling. in the Chemical Reaction Engineering Laboratory (CREL) at Washington University, Computer Automated Radioactive Particle Tracking (CARPT) Has Been Developed and Extensively Utilized for Measuring in a Non-Invasive Manner the Velocities, Turbulent Parameters and 3D Flow Mapping in Multiphase Flows. in Tis Study, Solids Flow Dynamics Has Been Investigated in "Cold-Flow" Circulating Fluidized Bed Risers using Non-Invasive Flow Techniques - CARPT and Computed Tomography (CT). Comparative and Symbiotic Analyses of the Results Obtained from CARPT and CT Have Been Used to Develop a Coherent Picture of the Solids Flow Field.
