Comparison of Single- and Two-Bubble Class Gas-Liquid Recirculation Models - Application to Pilot-Plant Radioactive Tracer Studies during Methanol Synthesis
Radioactive Gas Tracer Measurements Conducted during Liquid-Phase Methanol Synthesis from Syngas in a Pilot-Scale Slurry Bubble Column at the Alternate Fuels Development Unit (AFDU), La Porte Have Been Compared with Simulations from Two Mechanistic Reactor Models - Single-Bubble Class Model (SBCM) and Two-Bubble Class Model (TBCM). the Model Parameters Are Estimated from an Independent Sub-Model Gas and Liquid Recirculation, and the Long-Time-Averaged Slip Velocity between the Gas and Liquid/slurry in the Column Center Can Be as High as 50-60 Cm/s Depending on the Operating Conditions. Comparison of Experimental Data with Simulation Results from the Two Models Indicates that Accurate Description of Interphase Gas-Liquid Mass Transfer is Crucial to the Reliable Prediction of Tracer Responses. Coupled with a Correct Description of Gas and Liquid Recirculation, the Models Presented Here Provides a Simple and Fundamentally based Methodology for Design and Scale-Up of Bubble Column Reactors. © 2001 Published by Elsevier Science Ltd.
