Experimental characterization of structured packings using a miniaturized measuring cell and a liquid film thickness sensor
The continuous development of equipment in the chemical industry requires reliable experimental data to meet increasing demands regarding design, operation, and flexibility. Particularly in the design of separation columns, substantial uncertainties remain in established theoretical correlations, which makes experimental investigations essential. While cost-intensive pilot plants have traditionally been used for this purpose, miniaturized measuring cells offer an economical and highly flexible alternative with extended measurement capabilities.
As part of my research at Ruhr University Bochum, a miniaturized packed column is used and equipped with an innovative conductivity sensor. This sensor enables spatially and temporally resolved investigations of key process-relevant parameters, such as local liquid film thicknesses, liquid and tracer distributions, and local liquid velocities. The aim is to efficiently characterize new material systems and packing geometries and to systematically transfer the resulting findings to larger column scales.
