A catalyst slurry for a polymerization reactor can be prepared in a mixing tank
and the catalyst slurry fed to one or more storage tanks. The storage tanks can
include agitators so that the catalyst slurry is maintained at an essentially homogeneous
solids-to-liquid ratio. From the storage tank(s), the catalyst slurry can be pumped
to the polymerization reactor along a fluid passage having a flow meter. The flow
of the catalyst slurry can be continuous and/or adjusted based on a measured parameter.
The catalyst slurry may be continuously and reliability fed to the polymerization reactor.
