Liquid-liquid extraction (LLE) is an important unit
operation that allows one to separate fluids based on different solutes
being soluble to different degrees in different solvents. In the this
experiment, acetone is extracted by contact with water from a feed
stream containing an unknown concentration of acetone in butyl acetate
(BA).Purpose
The goal of this laboratory exercise is to study the performance of a
liquid-liquid extraction column.
Learning Objectives
The main learning objective of this laboratory exercise is to gain
experience in characterizing the behavior of a liquid-liquid extraction
column. To do this, one must examine such parameters as the composition
of the top and bottom products at various feed rates and compositions.
These parameters should be calculated theoretically using available
computer programs and determined experimentally from the column. |
