INTRODUCTION OF CONNECTION-TRAP Russian patent published in 2019 - IPC C08F2/00 C08F2/34 C08F10/00 

FIELD: instrument engineering.

SUBSTANCE: invention relates to a method for polymerisation of olefins in a polymerisation reactor system, which includes a gas-phase reactor, having an outlet for gas and one or more discharge lines, intended for unloading of polymer-containing flow, recirculation circuit for recirculation of gas leaving the reactor through gas outlet, back to reactor, system for separation of polymer for separation of reagents from polymer product in unloaded polymer-containing stream; and a recirculation system for recycling the reactants removed from the reactor in the polymer-containing stream discharge system back to the reactor. At that, connection-trap is introduced directly into one or more of the following places: recirculation circuit, polymer separation system and recirculation system.

EFFECT: method allows to eliminate excess water in gas phase contained in reactor, improving start of polymerisation.
