  • Apparatus and process for gas phase fluidized-bed polymerization
    Patent number: 6911504
    Abstract: A process for the continuous gas-phase (co)polymerization of one or more olefins for which a rising stream of a gas mixture, comprising at least one olefin to be (co)polymerized, maintains polymer particles in the course of formation in the fluidized state in a polymerization reactor, the said stream entraining fine particles above the fluidized bed outside the reactor, the said fine particles being substantially separated from the gas mixture using a separator, thus dividing the said stream into (i) one or more gas streams (A) substantially devoid of solid particles which is cooled and reintroduced below and/or into the bottom part of the fluidized bed, and (ii) one or more gas streams (B) comprising at least a portion of the said particles which is introduced into or above the fluidized bed, which process is characterized in that at least one of the gas streams (B) comprising the solid particles is introduced directly into the fluidized bed by a dilute-phase transport in a simple pipe, that is to say prefer
