liquid - liquid extraction of Benzoic acid

We were asked to extract benzoic acid from a kerosene-benzoic acid mixture. This was to be done using the stirred liquid-liquid extraction column in the senior laboratory. Fresh water was used as the continuous phase in the extraction. We were asked to measure the benzoic acid concentrations of the feed, raffinate, and extract streams. These measurements were to be made at several different steady-states. The number of theoretical stages and the height of the theoretical …
