Question

PHK and PLK are also applied in

(a) Hengstebeck’s equation

(b) Fenske’s equation

(c) Gilliland equation

(d) Homotomy equation

The question was asked in class test.

My doubt stems from The Jafarey, Dougles and Mcavoy Equation in chapter Column Process Design, Optimization and Shortcut Calculations of Distillation Design

Answer 1

Right answer is (a) Hengstebeck’s equation

To explain I would say: PHK and PLK are also applied in Hengstebeck’s method, while Fenske’s equation uses the relative volatility.
