Use of Electronic Worksheets for Calculation of Stagewise Solvent Extraction Processes

Abstract

The electronic worksheet, a powerful new tool for engineering analysis, is used to calculate flowsheets for stagewise solvent extraction processes. The algorithms presented give the component concentration of each stage at steady-state conditions and an estimate of the time to reach steady state. Any number of inlet and exit streams can be included and a different distribution ratio can be specified for each stage. The procedure is illustrated using a nuclear waste flowsheet. Although this paper deals with stagewise solvent extraction, it shows the utility of the electronic worksheet for many types of scientific and engineering calculations.
