Overall distillation column efficiency for most of the refinery columns can be given by (for ? = 0.07 - 1.4 cp and relative volatility < 4) (where ? = overall column efficiency, % ? = molal average viscosity of feed at average column temperature and pressure, cp ?p = pressure drop per tray, psi)
Options
A. ? = 17 - 61.1 log ?
B.
C. ? = 1.66 - 0.25 log ?
D. ? = 0.25 log ? - 1.67
Correct Answer
? = 17 - 61.1 log ?
