CLOSED LOOP RECYCLE OF VENT GAS IN POLYMERIZATION PROCESS

A fluidized bed olefin polymerization process incorporates a recycle of a vent gas (127), containing unreacted monomers, from the product purge bin vessel (117) to the polymerization reactor (101). The recycle of the vent gas minimizes the loss of unpolymerized reactants, thereby decreasing overall...

Zusammenfassung:	A fluidized bed olefin polymerization process incorporates a recycle of a vent gas (127), containing unreacted monomers, from the product purge bin vessel (117) to the polymerization reactor (101). The recycle of the vent gas minimizes the loss of unpolymerized reactants, thereby decreasing overall process and product costs.
