Abstract: A method for monitoring and controlling the polymerization in a polymerization vessel by using a camera viewing unit to (a) detect features of the polymer particles, or the particles' environment, (b) compare the features to pre-defined acceptable values of these features or the environment, and (c) if a variation from the pre-defined values is detected, act on process parameters to reduce or eliminate the variation.

Abstract: A process for the polymerization of olefins in gas phase carried out in a reactor having two interconnected polymerization zones, a first zone (riser) and a second zone (downcomer), wherein growing polymer particles: a) flow through the riser under fast fluidization conditions established by feeding a mixture of gas and liquid; b) leave the riser and enter the downcomer, through which the growing polymer particles flow downward in a densified form; and c) leave the downcomer and are reintroduced into the riser, thereby establishing a circulation of polymer between the riser and the downcomer; the reactor is operated at a temperature between 0° C. and 5° C. above the dew point of the riser gas at the operating pressure, and in the riser, besides the growing polymer particles and gas flow, an amount of liquid is present.
