[Biofuel] Methanol and PVC compatability

2005-10-20 Thread steven mesibov
I am trying to set up a methanol recovery still for my appleseed reactor
and was wondering if a PVC tank made from a sealed 6 diameter tube would
be acceptable.  According to a chemical compatibility chart I found it
says that PVC is okay to use with methanol but I wonder.  Is the reason
steel and not PVC recommended for the appleseed is because of the heat? 
In which case it should be okay for this application.  I am planning on
using a reversed compressor to provide the suction through the tank to
copper tubing in cold water from the hotwater tank vent.

Thanks for any thoughts and input.

Steve

Are you planning to recover the methanol at the end of the process 
before separating the by-product? You'll probably get a reverse 
reaction if you do.

No, I understand I need to drain off the fuel first to the wash tank and
then recover the methanol from the glycerol by product only.
