Assignment C: Liquid-Liquid Extraction Consider the ternary system of Acetic Acid/Isopropylether/Water. Equilibrium data is given in table 1. 1) Construct the ternary phase diagram and indicate raffinate and extract layers as well as single- and two-phase regions. Table 1: Fauilibria for Aretic. Arid/Isonronvlether/Water at 29.3K. A stream of water with 35 wt\% acetic acid (total flowrate of 100kg/h ) is extracted using an isopropyl ether solution ( 80kg/h ) containing 5wt% acetic acid due to recirculation in the process. The extraction is done in a single stage. 2) Determine the concentration of acetic acid in the extract and raffinate and the flow of each phase. It is aimed for a higher degree of extraction to the ether phase, so a multistage process is to be implemented. In this case the inlet ether phase is pure ether with a flow of 150kg/h, while the water flow is 50kg/h, the amount of acetic acid in the water remains unchanged at 35wt%. The aim is a water phase concentration of 10wt% at the end of the process 3) Determine the number of stages needed for this extraction. 4) What would be the minimum Solvent to feed ratio to use in this process? NOTE: Use Hunter-Nash method to setup the ternary diagram Assignment C: Liquid-Liquid Extraction Consider the ternary system of Acetic Acid/Isopropylether/Water.
