Solvent Distilling/Recovery
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...- ibmem

What does sorption means in pervaporation
again not answering "sorption=..." in one word but certainly of interest: http://www.membrane.nl/serve/theses/matthias/chapter_02.pdf §2.3 describing the sorption of simple gases in rubbery polymers and also http://www.membrane.nl/serve/theses/matthias/chapter_04.pdf page 63 introducing the...- ibmem

What does sorption means in pervaporation
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...- ibmem

Dehydration of ethanol using PSA
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...- ibmem
