Question

If a system has low interfacial tension _________ extractor is preferred.

(a) Packed column

(b) Pulse column

(c) Sieve plates

(d) Agitator column

I had been asked this question in an interview for job.

This question is from Extraction Equipments topic in section Liquid Extraction of Mass Transfer

Answer 1

Right answer is (c) Sieve plates

The explanation is: For a system with low interfacial tension need not need mechanical agitation so sieve plates are preferred.
