If the flow rate of each solvent stream is 50.0 kg/min, how many equilibrium stages are required?

A cross flow extraction system is being used to extract furfural from water into methyl-isobutyl ketone
(MIBK) at 25oC. The 150 kg/min of aqueous feed contains 0.11 wt% furfural. We desire a 90.0%
recovery of the furfural that enters the system in the aqueous feed. The entering solvent stream
contains 0.03 wt% furfural in MIBK. Assume flow rates of the aqueous raffinate streams and the extract
streams are constant. Equilibrium data is given in Table 1. If the flow rate of each solvent stream is 50.0
kg/min, how many equilibrium stages are required?
a. Solve graphically
b. Solve each stage analytically.
