摘要

Abstract

The dynamic analysis and optimal design of reactive extraction are challenging due to high nonlinearity of model equations and tough decision of judging criteria. In this work

a dynamic rate-based method is developed on gPROMS platform to get easy access to the solutions of reactive extraction with phase splitting. Based on rigorous criteria

dynamic analysis from initial state to final equilibrium (

e.g

evolution of phase composition

mass transfer rate and reaction rate) and optimal design of operating conditions (

e.g

extractant dosage and feed molar ratio) are achieved. To illustrate the method

the esterification of

-hexyl acetate is taken as an example. The approach proves to be reliable in the analysis and optimization of the exemplified system

which provides instructive reference for further process design and simulation of reactive extraction.
