Question

What is the most effective advantage of gravitational separators?

(a) They consume no power

(b) They just need small amount of space for operation

(c) They are cost effective

(d) Time taken for operation is very less

This question was posed to me in an internship interview.

I need to ask this question from Mechanical Dust Collectors topic in portion Steam Power Plant of Energy Engineering

Answer 1

Right option is (c) They are cost effective

To explain I would say: The most notable advantage of the gravitational separators is their cost effectiveness. Gravity separation is an attractive unit operation as it generally has low capital and operating costs, uses few if any chemicals that might cause environmental concerns.
