Rhodie,
The "Solvent Recovery Handbook" from Smallwood (McGraw-Hill) should become your bible: it describes the separation methods (distillations but also adsorption, membrane separation, extraction, coalescing, fractional freezing,..) and also the data part is very usefull.
regards,
PS...
again not answering "sorption=..." in one word but certainly of interest:

The separation mechanism of Pervaporation is a solution-diffusion mechanism:
The transport can be divided into 3 steps:
1. - sorption into the membrane at the upstream (feed) side
2. - diffusion through the membrane
3. - desorption into a vapour phase at the downstream (permeate) side
The flux...
Unclewil,
The MolSieves will do the job, but an EtOH dehydration from 7% to 0.5% is an ideal application for a pervaporation or a vapour permeation (membrane recovery):
- less energy (50% steam consumption)
- no consumption of dry EtOH (required for the regeneration of Mol.Sieves)
- no...
Allogo,
Pervaporation is a proven technology for the dehydration of ethanol from azeotrope to 99.5%.
It may be used for the concentration of lower concentration alcohol, an info is available under:
