1.1.8 Steam distillation vs zeotropic distillation

Points: 3 No answer

The table below shows the vapour pressures of two different pure compounds as a function of temperature. For the further progress of this exercise we first assume that the two compounds form a zeotropic mixture. Later we will assume that the two compounds are not miscible with each other (hetero-azeotrope).

$$T$$ in $$K$$$$p^{sat}_1$$in $$MPa$$$$p^{sat}_2$$ in $$MPa$$

$$p^{sat}_1+p^{sat}_2$$ in $$MPa$$

TASK 1 (zeotrpic mixture):
The boiling point temperature of pure compound 1 at an overall pressure of $$p_{tot}=0.10064 MPa$$ is $$K$$.
The boiling point temperature of an equimolar mixture at an overal pressure of $$p_{tot}=0.1 MPa$$ is $$K$$.

TASK 2 (hetero-azeotrpic mixture):
We now assume that the sames compounds are not miscible with each other. The mixture forms a hetero-azeotrope. The hetero-azeotrope contains 1mol of compound 1 and one mol of compound 2.
The boiling point temperaure of the hetero-azeotrope at a total pressure of $$p_{tot}=0.10212506 MPa$$ is $$K$$.
