Abstract
A process for polymerizing one or more monomers is provided. In at least one specific embodiment, the process includes preparing a mixture comprising the one or more monomers, a catalyst system and a fluorinated hydrocarbon, preferably a hydrofluorocarbon. A fluorinated hydrocarbon containing stream, a polymer product stream and a waste stream are recovered from the mixture. At least a portion of the waste stream is sent to a non-flare decomposition system to produce a destructed waste stream, and the destructed waste stream is released to atmosphere.

A process for polymerizing one or more monomers, comprising:
- preparing a mixture comprising the one or more monomers, a catalyst system and a fluorinated hydrocarbon;
- recovering from the mixture, a fluorinated hydrocarbon containing stream, a polymer product stream and a waste stream;
- sending at least a portion of the waste stream to a non-flare decomposition system to produce a destructed waste stream;
- and
- releasing the destructed waste stream to atmosphere.
A polymerization process, comprising
- polymerizing one or more monomers in the presence of a diluent comprising fluorinated hydrocarbon to form a polymer;
- recovering a majority of the polymer in a polymer product stream and a majority of the fluorinated hydrocarbon in a purge stream;
- separating the purge stream into a plurality of streams including a fluorinated hydrocarbon containing stream and a waste stream;
- and
- sending at least a portion of the waste stream to a thermally or catalytically oxidized decomposition system.
A polymer recovery process, comprises:
- separating fluorinated hydrocarbon from a polymer;
- recovering the separated fluorinated hydrocarbon in a purge stream and the polymer in a product stream;
- separating the purge stream into a plurality of streams including a fluorinated hydrocarbon containing stream and a waste stream;
- and
- sending at least a portion of the waste stream to a thermally or catalytically oxidized decomposition system.
