Multiscale Hydrodynamic Measurements in Trickle Bed Reactors

Experimental data on liquid-solid mass transfer, wetting efficiency, and hydrodynamic behavior in trickle bed reactors. The dataset was created by Rita Harris using electrochemical limiting current techniques across five laboratory-scale columns of varying dimensions. Measurements were taken at bed, particle, and sub-particle scales under steady-state trickle flow conditions.

Use Cases

• Modeling liquid-solid mass transfer coefficients based on superficial liquid and gas velocities.
• Analyzing the impact of distributor design (point-source vs. multipoint) on wetting efficiency.
• Studying radial and axial variations in mass transfer behavior across different bed depths.
• Evaluating the effect of prewetting methodology and restart procedures on reactor hydrodynamics.

Strengths

• Data covers five distinct column geometries with internal diameters from 12 mm to 105 mm.
• Measurements were conducted at three scales (bed, particle, sub-particle) using three custom electrode configurations.
• Steady-state conditions were rigorously defined as a stable current response within ±3% over three minutes.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is limited to laboratory-scale experiments; industrial-scale applicability requires validation.
