Instead of using water wash, methanol can be directly removed by using pervaporation or vapor permeation with polymeric membranes. Please contact Sulzer Chemtech (infomembranes(at)sulzer.com) for additional information.

RW,
it doesn't as the driving force is the difference in partial pressures of the permeating components on feed and permeate side. And partial pressure of a component in a mixture is only depending on its composition (activity coefficients) and its temperature.
Therefore by either increasing the...
RW,
1. The only possibility to run pervaporation (liquid feed) at constant temperature is installing the system in an oven (especially for theoretical experiments). PS is right with vapor permeation, but the swelling and thus fluxes with vapor are different (= lower)
2. 60 °C is not the optimal...
jdavis,
is this the price for membrane only, cut or installed?
As most of the suppliers do not just sell membranes but having them installed in modules or in complete units, you have to know where your price is deducted from.
As an average you can say that 1 sqm. PVAmembrane in a plate 'n frame...
The SMART chemical company no longer exists as Smart - and as far as I know they stopped producing membranes in 2001.
In case you need more information on pervaporation you can also send an email to info@sulzermembranes.com - they also have an office in UK.
Good luck :-)
