Solution to Tutorial 4 Given: F = 1000 kg-mole/hr‚ xF = 0.20 (ethanol is MVC) Feed is saturated liquid‚ thus q = 1.0 xD = 0.80‚ xB = 0.02 (maximum); R = 5/3 First‚ plot the equilibrium curve using the VLE data given. Note that you need to convert mole% ethanol into mole fraction. Then‚ apply the McCabe-Thiele method to find the number of theoretical (equilibrium) trays required for the separation. Step 1: Since R and xD are known (5/3‚ and 0.80 respectively)‚ plot the ROL equation - it
