Extraction of Acetic Acid from Water Using Isopropyl Ether
Extraction of Acetic Acid from Water Using Isopropyl Ether
This Demonstration is a study of the separation of acetic acid from water using isopropyl ether for a single-feed countercurrent extractor. You can vary the flow rate and acetic acid composition of the feed, the flow rate of the solvent, which is pure isopropyl ether, and the raffinate composition in acid. The cyan and purple lines are the operating and tie lines, respectively. The red and blue dots are on the raffinate and extract curves. They correspond to compositions of the raffinate and extract streams at various locations in the extractor. Stages are stepped off using the tie lines and the operating lines alternatively until the raffinate composition is lower than the specification. The number of equilibrium stages is displayed.
