Rayleigh equation applies to _________________ distillation ?
Correct answer: A. Differential
- A. Differential
- B. Flash
- C. Equilibrium
- D. Molecular
Explanation
The Rayleigh equation is obtained from an unsteady material balance on a still and therefore applies to differential, or batch, distillation. Flash distillation is treated as a single equilibrium stage rather than by the Rayleigh equation.
