Patent number: 8293857Abstract: Process for polymerization of ethylene using a catalyst system including (i) a solid catalyst of Ti, Mg and halogen, (ii) a first activator which is at least one trialkylaluminium compound of the formula AlR3, where each R is independently a C2 to C20 alkyl radical, and (iii) a second activator which is at least one alkylaluminium chloride of the formula AlR?2Cl, where each R? is independently a C2 to C20 alkyl radical. The second activator is introduced directly into the polymerization reactor, without precontact with the solid catalyst, continuously or semi-continuously, and at a maximum rate of introduction at any time corresponding to less than 10 ppm by weight of chlorine relative to the rate of polyethylene production.Type: GrantFiled: October 15, 2008Date of Patent: October 23, 2012Assignee: Ineos Europe LimitedInventors: Alain Berardi, Andre Frederich, Dominique Jan, Jean-Jacques Kuhlburger, Anthony Sgard, Alain Van Daele

Patent number: 8183333Abstract: Polymerisation process in which polyethylene is produced in slurry in a polymerisation reactor in the presence of a Ziegler Natta catalyst and an activator, and a stream or slurry containing the polymer is withdrawn from the reactor and transferred to a flash tank operating at a pressure and temperature such that at least 50 mol % of the liquid or non-polymer component of the stream entering the flash tank or slurry is withdrawn from the flash tank as a vapour and at least 98 mol % of the vapour withdrawn from the flash tank is capable of being condensed at a temperature of between 15 and 50° C., without compression. A by-product suppressor, which reduces the amount of by-product formed per unit of polyethylene produced by at least 10%, compared with an identical polymerisation process where the by-product suppressor is not present, is used in the reactor. The molar ratio of the by-product suppressor added to the reactor to titanium added to the reactor is between 0.2 and 1.Type: GrantFiled: August 29, 2008Date of Patent: May 22, 2012Assignee: Ineos Manufacturing Belgium NVInventors: Benoit Koch, Daniel Marissal, Marc Parisel, Brent R Walworth, Andre Frederich
