Claim One:
1. A gas-phase polyolefin reactor system, comprising: a) a control valve, wherein a first stream is connected to an input end of the control valve and to an input end of a high-flow valve and a second stream is connected to an output end of the control valve and the high-flow valve, wherein the second stream is connected to a third stream, wherein the third stream is connected to an input of a gas-phase polyolefin reactor; b) wherein the first, second and third streams comprise a reaction component, wherein an empirical model predicts a required amount of a reaction component based upon an initial concentration and a selected ending concentration, and wherein a flow meter measures a flow rate of the first stream near the input end of the high-flow valve and outputs the measured flow rate to a totalizer.
