1. Separation Technology TKP 4105
Diffusion (binary): Fick’s law
Distillation (binary): Both components A and B are volatile.
Absorption (ternary): Gas component A diluted in an inert carrier gas C contacted with liquid B (which maybe volatile).
Extraction (ternary): Three mutually soluble components.

2. So, what’s all about? Mass balances, mass balances, mass ...
Units, units, units ...
Distillation (constant pressure): Difference in volatility caused by changes in T.
Absorption (constant T and P): Driving force is partial pressure.
Extraction(constant T and P): Driving force is liquid mole fraction.
