Liquid-Phase Tracer Responses in a Cold-Flow Counter-Current Trayed Bubble Column from Conductivity Probe Measurements


Liquid-Phase Mixing in a Cold-Flow Counter-Current-Flow Bubble Column Reactor with Trays Has Been Evaluated. a Developed Filtering Technique [P. Gupta, M.H. Al-Dahhan, M.P. Dudukovic', P.L. Mills, a Novel Signal Filtering Methodology for Obtaining Liquid-Phase Tracer Responses from Conductivity Probes, Flow Meas. Instrum. 11 (2) (2000) 123-131.] Was Used to Extract the Liquid-Phase Concentration Responses from the Conductivity Probe Data in Two Phase Gas-Liquid Flow with Systematic Corruption. Conductivity Probe Responses to a Pulse Input of KCl Liquid Tracer Were Measured at Various Point-Wise Locations in an 8 In. Diameter Clear Acrylic Column using Air and Water as the Gas-Liquid System. the Superficial Gas and Liquid Velocities Were Selected to Span Those Encountered in a Commercial Unit using a Pipe-Type Gas Sparger with a Number of Laterals. Results from Tracer Experiments Are Presented Along with a Cross-Correlation of Signals to Estimate the Characteristic Residence Time of the Liquid on a Tray. the Utility of the Filtering Algorithm for a Broader Range of Gas-Liquid Flows is Also Discussed. © 2006 Elsevier B.V.
