BACT for IPA/phenol/formaldehyde vapor

Friday, Oct 27, 2000


A facility uses phenolic resin in its process. The resin has
to be used (Source reduction is not an option). Upon
heating, vapor is released which contains isopropyl alcohol
(around 20%), and small amounts of phenol and formaldehyde.

There are questions related to how to handle this vapor, and
what is the best available control technology (BACT)?. One
approach is to incinerate the vapor in a natural gas burner.
-  Anyone has experience on the success of this approach?
-  Would this incineration require air permits?
-  Would this be considered on-site treatment, requiring a
   special permit?

Another possibility is to look at condensing the IPA and
possibly recycling it, if the quality is acceptable. Any
experience or suggestions along these lines?

Thank you all. Have a nice day.
