Greeting to Tom
there is one intersting method you can use for dehydrating
comercial ethanol using extraction with castor oil.
Now adys importing from Brasil is made much simpler than before
There si information available about this process here in this list archives.
We can help to deign the project as combined oil is found to give
better performance for BioD. What I mean is you can first extract
pure etanol using caster oil and tehen use this for tranesterification
process./
May be Keith may know some one have tried this process.
Since our small research group work on novel procee design ,we
would like to to have colaborative work in this important field.
Since you are nearby country and also Mercsul countries , we
can really have BIGBROTHER type colaboration.
Thanking you
