Question

In re-fluxing, the re-flux ratio needs to a minimum.

(a) True

(b) False

I got this question in class test.

Asked question is from Unit Operations in portion Equilibrium Stage Operations, Unit Operations – Extraction, Crystallization and Filteration of Food Engineering

Answer 1

Correct answer is (b) False

For explanation I would say: The re-flux ratio being minimum means that an infinite number of plates are required and vice-versa. Hence the re-flux ratio needs to be more than the minimum.
