Title: Solvent recovery from aqueous effluent using process diluent in the caustic-side solvent extraction (CSSX) process.

Abstract

In this work, solvent recovery from aqueous CSSX process raffinate effluent was tested using the process diluent (Isopar{reg_sign}L). A model was developed to obtain stage efficiency for the diluent contact stages. The model was used to fit experimental data from a 19.8-hr solvent recovery test. Diluent-in-aqueous entrainment was measured during the test. Vacuum distillation was used to concentrate the solvent components, BOBCalixC6 and modifier, in the diluent used in solvent recovery. Using the results, a feasibility study was performed to compare the annual cost of lost solvent under each of four solvent recovery options. These options were decanter tank, centrifuge, two-stage diluent contact using centrifugal contactor, and no solvent recovery action.
