摘要

An online optimizer was developed to industrial airlift reactors in a phenol plant. The optimizer is integrated with a multivariable controller and online composition analyzers. The objective is to reduce the by-products formation during the cumene oxidation. Using an online fit model, a SQP subroutine calculates optimal composition values to the reactors and these values are sent to the multivariable controller as new setpoints. The average by-products reduction resulted in 4.7% (mass fraction), which means an important contribution to the annual plant productivity.
