The steady state characteristic of the liquid-liquid extraction process of residual water phenol in pure benzene as solvent, x₁
= f(F_B) is to be determined. The process and its equilibrium curve, y₁
= f(x₁), are represented in Fig. 6.17.

The data are the following: F_A
= 10 m³/h, F_B
= 3.57 m³/h, x0 = 8 kg/m³, x1 = 0.5 kg/m³, y¹
= 25 kg/m³, T^∘
= 25
^∘C. All data are at steady state. How does the steady state characteristic change when x₀
= 10 kg/m³
and what value has to be taken by F_B
to keep y₁
= 25 kg/m³?
