Re: Concentration methods for DMF



> Karl --- In P2 Infohouse
(http://wrrc.p2pays.org/nframe.asp?page=SearchRLIBY.asp) we have a 1991
case study about a DuPont fiber plant that recovered DMF by distillation.
That case study isn't on line yet, but I'd be happy to fax it to you.  The
write-up we have isn't very detailed, but  you could contact that plant and
learn from their experience.

If distillation isn't economical another, possibly naive suggestion, but
would be to simply put the membranes in an oven, perhaps an infrared one,
to evaporate the DMF.
