dc.description.abstract Liquid-liquid extraction is one of the simplest and cost effective separation process which is well known and well investigated, however, the equilibrium data for mutual solubility and tie-lines are difficult to correlate and be applied. Many works introduced methods that predict liquid – liquid tie-line data, but the mutual solubility data is still plotted on binodal cure on equilateral triangle. In this work the extraction of acetic acid from a mixture of acetic acid and water was carried out by using isopropyl ether to design a liquid – liquid extraction column (sieve Tray). The equilibrium data of water, acetic acid and isopropyl ether ternary systems were determined at 25̊ C and 1 atm; and plotted on binodal curve on equilateral triangle. The construction of the tie-lines on the binodal curve to determine the number of theoretical stages was done graphically using the relevant correlations. This required experimental determination of the mutual solubility and tie-line data; the graphical method derived by Treybal is used to obtain the number of theoretical stages in the present work and proved to be accurate and easy to apply. The number of stages was determined using this method as well as all other design parameters of a sieve tray extraction column. Aspen plus simulation package was used to calculate the number of theoretical stages; the design is also made through hand calculations for a complete design of extraction column; the stages were compared with manual calculations, and it is found to be in agreement with the method investigated in this study. en_US
