Steady-State Simulation of the Counter Current Liquid-Liquid Ex-Traction: Trimetozine Synthesis as a Case Study

The countercurrent liquid-liquid extraction is a crucial step in industrial process to purify and extract a compound of inter-ests for its impurities. This step requires generally challenging and time-consuming optimisation of numerous factors that affect the overall yield of extraction and the energy needed. The simulation of this process has been investigated in this pa-per using a Non-Random Two Liquid model implemented as a thermodynamic method in Aspen. The outcome of this model enables the evaluation of the partition coefficients of the different analytes of a mixtures at the different compart-ments of extraction platform. In addition, this steady-state model allows a more straightforward optimisation of the factors that drive the performance of extraction.
