Abstract:
1. An apparatus for preparing, measuring, and feeding a catalyst slurry to a polymerization reactor, wherein the apparatus comprises: a mixing tank for mixing a catalyst slurry comprising a solid catalyst in a liquid medium, wherein the mixing tank comprises an agitator; a storage tank for maintaining the catalyst slurry, wherein the storage tank is fluidly connected to receive the catalyst slurry from the mixing tank; a pump for delivering the catalyst slurry from the storage tank to a polymerization reactor through a fluid passage; a flow meter adapted to measure the flow of the catalyst slurry through the fluid passage; and a controller that receives a flow signal from the flow meter indicative of the flow of the catalyst slurry, wherein the controller directs the pump to adjust the flow of the catalyst slurry based on the flow signal.
