Description:
<jats:title>Abstract</jats:title><jats:p>The presented contribution reports on comprehensive hydrodynamic investigations in two pulsed sieve‐plate extraction columns (PSE) on a pilot scale. The experiments were conducted with three different sieve plate geometries employing test systems recommended by EFCE, under varying pulsation conditions and throughputs. The results of the investigation add to the existing knowledge of relationships between hydrodynamic parameters, drop size, hold‐up, flooding throughput and mixing and operating parameters. They also provide useful information for scale up, selection of sieve‐plate geometry, most favorable operating range, and constructive design of equipment. On the basis of measurements, analytical methods are recommended for prediction of PSE hydrodynamics.</jats:p>
