Nonlinear product property control in industrial gas‐phase polyethylene reactors
Abstract
Abstract A nonlinear model‐based scheme is developed for product property control in industrial gas‐phase polyethylene reactors. The controller regulates instantaneous melt index and density, and provides servocontrol during grade changeovers. Hydrogen and butene feed rates are manipulated to force the product properties onto desired trajectories. During grade changeovers, these trajectories are determined from off‐line dynamic optimization …
