Chapter 4, Problem 4.17P

Interpretation Introduction

Interpretation:

The mole fraction, x, of the vapor exit stream should be calculated.

Concept Introduction:

Riedel equation is represented as follows:

  $\frac{\Delta H_n}{R{T}_n}=\frac{1.092(\ln P_c-1.013)}{0.930-T_{rn}}$

  $T_{rn}=\frac{T_n}{T_c}$ and $P_r=\frac{P}{P_c}$

  $T_n$ =Normal boiling point

  $T_c$ = Critical Temperature

  $P_c$ = Critical Pressure

  $\Delta H_n$ = Latent heat of vaporization

Watson correction is represented as follows:

  $\frac{\Delta H_v}{\Delta H_n}={\left(\frac{1-T_{rsat}}{1-T_{rn}}\right)}^{0.38}$
