Patent number: 10829610Abstract: The present invention deals with a process for polymerising olefins in a solution and withdrawing a stream of the solution from the polymerisation reactor and passing it to a sequence of heating steps. The heated solution is passed to a separation step, which is conducted at a pressure of no more than 15 bar and in which separation step a liquid phase comprising the polymer and a vapour phase coexist. A vapour stream and a concentrated solution stream comprising the polymer are withdrawn from the separation step. At least a part of the vapour stream is passed to the first polymerisation reactor, to the second polymerisation reactor or to both.Type: GrantFiled: December 21, 2016Date of Patent: November 10, 2020Assignee: BOREALIS AGInventors: Mohammad Al-Haj Ali, Michiel Bergstra, Erik Eriksson, Guhan Mathivanan, Jukka Räsänen, Henry Sleijster, Sameer Vijay, Christof Wurnitsch, Samuli Zitting, Vasileios Kanellopoulos, Jani Aho
