An 11.5 wt% mixture of acetic acid in water is to be extracted with 1-butanol at atmospheric pressure and 25°C in countercurrent operation. We desire outlet concentrations of 0.5 wt% in the water and 9.6 wt% in the butanol. Inlet butanol is pure. Find the number of equilibrium stages required and the ratio of water to 1-butanol by using the McCabe-Thiele diagram design method. The acetic acid equilibrium distribution is given by K = 1.613 (wtfr. in butanol/wtfr. in water). Required steps: a. Convert the streams and equilibrium data to mass ratio units b. Plot the equilibrium curve c. Plot the operating curve to determine the water to 1-butanol ratio d. Step off the equilibrium stages

Question

An 11.5 wt% mixture of acetic acid in water is to be extracted with 1-butanol at atmospheric pressure
and 25°C in countercurrent operation. We desire outlet concentrations of 0.5 wt% in the water and 9.6
wt% in the butanol. Inlet butanol is pure. Find the number of equilibrium stages required and the ratio
of water to 1-butanol by using the McCabe-Thiele diagram design method. The acetic acid equilibrium
distribution is given by K = 1.613 (wtfr. in butanol/wtfr. in water). Required steps:
a. Convert the streams and equilibrium data to mass ratio units
b. Plot the equilibrium curve
c. Plot the operating curve to determine the water to 1-butanol ratio
d. Step off the equilibrium stages
