Patent number: 9133291Abstract: Process for transferring polyolefin particles from a first gas-phase polymerization reactor to a second gas-phase polymerization reactor in a multistage polymerization of olefins carried out in at least two serially connected gas-phase polymerization reactors, wherein the first gas-phase reactor is a fluidized-bed reactor comprising a gas distribution grid and a settling pipe, which is integrated with its upper opening into the distribution grid and contains a bed of polyolefin particles which moves from top to bottom of the settling pipe, the process comprising the steps of introducing a fluid into the settling pipe in an amount that an upward stream of the fluid is induced in the bed of polyolefin particles above the fluid introduction point; withdrawing polyolefin particles from the lower end of the settling pipe; and transferring the withdrawn polyolefin particles into the second gas-phase polymerization reactor, process for polymerizing olefins comprising such a process for transferring polyolefin pType: GrantFiled: December 4, 2012Date of Patent: September 15, 2015Assignee: Basell Polyolefine GmbHInventors: Massimo Covezzi, Giuseppe Penzo, Gabriele Mei, Giulia Mei, Pietro Baita, Gerhardus Meier, Antonio De Lucia, Ulf Schueller, Gianpiero Ferraro
