Question

McCabe Thiele Graphical Design and Murphree Tray Efficiency
Feed=200 mol/h xF=0.42 xd=0.97 xw=0.011 R=2.5
D= 85.3 mol/h W=114.7mol/h
Theoretical trays found as 9.5 ( with reboiler)
Murphree tray eff. is estimated as 0.55. Determine the actual number of trays needed by stepping off the trays using the tray eff of 0.55. Also, calculate the overall tray eff Eo McCabe Thiele Graphical Design and Murphree Tray Efficiency

Explanation / Answer

Actual number of trays = 11.5

Therefore overall tray efficiency Eo = Theoretical trays / actual number of trays = 9.5/11.5 = 0.826

Therefore Eo = 82.6 %
