Separation Processes

Use this for “A saturated liquid feed holds 40% of the light component; the distillate must reach 95% and α = 2.5. What is the minimum reflux ratio?”

Use this for “A column runs at reflux ratio 3 with a 90% distillate. What are the slope and intercept of the top operating line?”

Use this for “α = 2.5, a saturated liquid feed at 40%, 95% distillate, 5% bottoms and R = 2.167. How many stages, and which is the feed stage?”

Use this for “Clean solvent must cut a gas from 2% solute to 0.1%, with y = 1.5x. What is the least L ÷ G, and the design L ÷ G at 1.5 times it?”

Use this for “KD = 2 and S/F = 1.5 in all: what is left after three washes of 0.5 each, and after one wash with the lot?”

Use this for “A membrane has P = 2.4 barrer for O₂ and 0.4 barrer for N₂. How rich in O₂ is the permeate from air?”
