**Question 14**
A solute is absorbed from a vapor stream mixture using a non-volatile liquid. The entering vapor is 14.0 mole% solute, and the entering liquid is solute-free. The solute present in the vapor is 90% absorbed and the concentration of the liquor at the bottom of the tower contains 7.30 mole% solute. Assuming an overall vapor stream flow rate of 100 moles/hr the equilibrium and operating lines for a counter-current separation have already been graphed (This figure is provided for your use / consideration).
**Graph Description:**
- The graph displayed below is a plot with mole fraction of solute in the liquid (y-axis) versus mole fraction of solute in the vapor (x-axis).
- Both axes range from 0.0000 to 0.1600.
- There are two lines shown on the graph:
- A green line that represents the equilibrium line.
- A blue line representing the operating line.
- The equilibrium line has a lower slope starting from the origin and moving toward the upper right, while the operating line has a higher slope and also starts from the origin moving upward.
**Based on the information available a basic and any calculations deemed necessary:**
1. What is the minimum number of equilibrium stages necessary to achieve the desired separation? (Based on a graphical solution)
- [Text Box for Answer]
2. What is the liquid flow rate for this column (the operation shown)?
