The Tedlar process converts VF into polyvinyl fluoride (PVF).VF is generated at another
DuPont facility, shipped in on tanker trucks and stored at the Buffalo facility in high
pressure storage tanks. VF is pumped from the storage tanks to a reactor and reacts to
form PVF slurry in water and unreacted VF. After the reactor, the PVF water slurry passes
through separators to remove the VF. The VF is pumped from the separators by compressors
and recycles back to the reactor. After the separators, steam is injected into the PVF
slurry to raise the temperature and vaporize any VF present in the slurry. The heated
mixture passes through a small slurry flash tank where the residual VF is released to the
atmosphere1.
