Efficient Shortcut Method for Determining the Process Window in Stirred‐Pulsed Extraction Columns. Issue 3 (21st January 2021) - Schmalenberg, Mira
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. Abstract : A shortcut method was developed to determine flooding points in stirred‐pulsed extraction columns for industrial systems, which often contain unknown impurities. This method is presented and evaluated by two substance systems. A DN15 stirred‐pulsed extraction measurement cell and column were used.
