PROCESS FOR POLYMERISATION OF OLEFIN MONOMER IN CONTINUOUS GAS FLUIDISED BED, NOZZLE FOR ATOMIZING A FLUID IN A FLUIDISED BED

摘要

The process is for the polymerization of oleyl olefin, especially ethylene, propylene, or a mixture thereof, with other alpha-olefins in a mainstream gas fluidized bed. The recirculated gas stream is cooled to quench a fluid (e.g., a quarry), at least a portion of this fluid is separated, and sprayed under pressure directly into a fluidized bed through a nozzle (1) equipped with a thermal imaging device (s). is created in zone (5). The spray-forming zone (5) is protected by a wall, shielded from particles of the fluidized bed, from which this wall can be a tube or a sheet. The nozzle used in the process has two or more bristle outlets. Each of these broths is independently fed and regulated to provide a perfect up-and-down feed to the bed. ŕ
