Efficient Shortcut Method for Determining the Process Window in Stirred‐Pulsed Extraction Columns

Abstract

Recent studies showed the superior separation performance of stirred‐pulsed columns of different diameters in liquid‐liquid extraction processes. Here, an efficient shortcut method will be presented, which is time and resource‐efficient as well as cost‐effective to determine the operational window of these columns for industrial separation tasks. Savings in time of less experiments and costs of materials consumption can be estimated with up to 30 %. The presented method is particularly suitable before the application of new chemical systems, which are particularly cost‐intensive and scarce in material supply.

Design of a Process‐Intensified Liquid‐Liquid Extraction Cell for Higher Temperature and Pressure

“…At the Laboratory of Equipment Design, the stirred-pulsed DN15 extraction measurement cell has been developed [8,9]. It combines the low effort of miniaturized devices with the high efficiency of liquid-liquid extraction.…”

“…It combines the low effort of miniaturized devices with the high efficiency of liquid-liquid extraction. Process intensification concepts are applied by introducing stirring and pulsation to achieve a higher separation efficiency while offering a high maximum throughput [8,9]. Other approaches for process intensification are, for example, by introducing reactive components [10], using centrifugal contractors [11], or scaling down the extraction device to the microfluidic level [12].…”
