Q. Pick out the correct statement. (Solved)
1. Ponchan-Savarit method is more accurate than McCabe-Thiele method to determine the number of theoretical stages required for the separation of non-ideal binary system by distillation
2. A sharp decrease in pressure drop is an indication of flooding in a distillation coloumn
3. Solvent used in extractive distillation should be of high volatility
4. Flash distillation is suitable for separating components which have very close boiling temperature
- a. Ponchan-Savarit method is more accurate than McCabe-Thiele method to determine the number of theoretical stages required for the separation of non-ideal binary system by distillation
