Mc Cable Thiele method used for finding theoretical stages in a distillation column assumes that the_____________________?
Correct answer: D. All A., B. and C.
- A. Sensible heat differences are small, because the temperature changes from tray to tray is small
- B. Trouton's rule is applicable
- C. Liquid/vapor loading across the column remains constant
- D. All A., B. and C.
Explanation
The McCabe-Thiele method uses constant molal overflow: sensible-heat effects are neglected, vapour and liquid molar flow rates remain essentially constant, and latent-heat behavior is approximated using relations such as Trouton's rule. Hence all three assumptions are included.
