Process
First Claim
1. A process for the polymerisation of olefins in a polymerisation reactor system, the polymerisation reactor system comprising a reactor and further comprising at least first and second introduction points by which the same reaction component may be introduced directly at different locations on the reactor system, the process comprising:
- (i) at a first time introducing the reaction component through at least the first introduction point and such that a proportion X of the reaction component which is introduced through said first and second introduction points is introduced through the first introduction point, and(ii) at a second, later, time introducing the same reaction component through at least the second introduction point and such that a proportion Y of the reaction component which is introduced through said first and second introduction points is introduced through the first introduction point,wherein Y is less than X,and further wherein at least one of the first and second introduction points is located on the reactor system at a location not on the reactor.

Abstract
Process for polymerizing olefins in a polymerization reactor system including at least first and second introduction points by which the same reaction component may be introduced directly at different locations on the reactor system. At a first time, the reaction component is introduced through at least the first introduction point, such that a proportion X of the reaction component which is introduced through the first and second introduction points is introduced through the first introduction point. At a second, later, time the same reaction component is introduced through at least the second introduction point and such that a proportion Y of the reaction component which is introduced through the first and second introduction points is introduced through the first introduction point. Y is less than X, and at least one of the first and second introduction points is located on the reactor system at a location not on the reactor.

6. A process for the polymerisation of olefins in a polymerisation reactor system, the polymerisation reactor system comprising at least a first introduction point and a second introduction point, the process comprising introducing the same reaction component directly at different locations on the reactor system, wherein at a first time the reaction component is introduced through the first introduction point but not the second introduction point, and at a second, later, time the same reaction component is introduced through the second introduction point but not the first introduction point.

18. A polymerisation reactor system comprising:
-
(a) a first introduction point connected to a source of a reaction component and by which the reaction component may be introduced directly to the polymerisation reactor system at a first location, (b) a second introduction point connected to the same source of a reaction component and by which the reaction component may be introduced directly to the polymerisation reactor system at a second location different to the first location, and (c) a control system which controls the supply of the reaction component to the polymerisation reactor system and which prevents the reaction component being introduced through both the first and second introduction points at the same time.
