Separation Process Problem Set 1
1. Calculate the relative volatility of benzene-Toluene
Solution:
𝑌𝐵
◦
𝑋𝐵 𝑃𝐵 300
𝑆𝐹 = α = (1−𝑌𝐵) = ◦ =
133
= 2.26
𝑃𝑇
(1−𝑋𝐵)
2. What will be the concentration of oxygen dissolved in water at 298 K when the solution
is in equilibrium, with air at 1 atm total pressure?
Solution:
4
0. 21 = 𝐻𝑥𝐴 = 4. 38 × 10 𝑥𝐴
−6
𝑥𝐴 = 4. 80 × 10
3. Given the relative volatility of A with respect to B as 0.75. Calculate the vapor pressure
of A if the vapor of B is 400 mmHg.
Solution:
𝑃𝐴 = α (𝑃𝐵)
= 0.75 (400 mmHg)
𝑃𝐴 = 300 mmHg
