Dear jdavis
PVA-Membranes are not expensive and Pervaporation is used because it is less expensive than other technologies when you have to break an azeotrope.
Membrane Systems suppliers (not only manufacturers) are listed under
hope it helps,
Pierre

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 module is around $500-750(incl. membrane cutting and module assembling) - 1/3 of your price!
Does it look more promissing to your project now?

Dear jdavis,
why not to describe your application and so we could discuss advantages / disadvantages of the pervaporation or vapour permeation. Thanks in advance. Pierre

Dear Pierre
I do not have a specific application. I am putting together information on the options in this area for the US EPA. However, we have had little and apparently erroneous information on the costs of the polymeric membranes. This is still confounded by the variation in costs of these units related to peripheral equipment, particularly heat exchangers, that are application dependent.Thanks. Jim
