Flowsheet Simulation of Cobalt–Nickel Separation by Solvent Extraction with Trihexyl(tetradecyl)phosphonium Chloride

Abstract

S. (2018). Flowsheet simulation of cobalt-nickel separation by solvent extraction with trihexyl(tetradecyl)phosphonium chloride. Industrial and Engineering Chemistry Research, 57(30). https://doi.org/10.ABSTRACT Solvent extraction is widely used for selective separation of metals from solutions. Ionic liquids are showing potential for this purpose. To date, little research has focused on design, operation and optimization of solvent extraction flowsheets using ionic liquids. This work addresses this gap in knowledge, aiming to support development, design and optimization of such solvent extraction processes. In this work, a general flowsheet simulation model is developed and applied for the case of cobalt-nickel separation using ionic liquid * Corresponding author, email: Hongyan.chen@manchester.ac.uk ORCID

“…Along this line, the work by Castillo-Landero et al proposes a systematic approach for process intensification (tasks integration into fewer pieces of equipment), considering sustainability metrics. Focusing on specific situations, the work by Aeowjaroenlap et al addresses the development and implementation of a rigorous model representing the reactions involved in the acetylene hydrogenation, leading to significant improvements in steam cracking economics and process performance; Ledezma-Martínez et al exploit the interactions between separation and heat recovery tasks in crude-oil distillation systems to reduce the requirements of utilities; Bürger et al develop an improved model to predict phosphorus dynamics in biotechnological systems, accounting for both physicochemical and biological processes; Zhou et al address the waste treatment and recovery in the nylon production processes; and Chen and Jobson study the design, operation, and optimization of solvent extraction flowsheets, using ionic liquids for the selective separation of metals from solutions. The specific requirements of the pharmaceuticals sector deserved special attention in the ESCAPE-27 program, as in the works of Montes at al., who analyze ways to improve plant design and operation to reduce the effects of uncertainties and disturbances over the specifications of the active pharmaceutical ingredients; and Sugiyama et al, who refer to the requirements for solid drug manufacturing usually found in the pharmaceuticals sector to propose a decision support method for the choice between batch and continuous technologies.…”
