Abstract :
The plantwide operability of a commercial 12-stage whey ultrafiltration (UF) process is studied in this paper. In this work, the plantwide system is treated as a network of 12 process units with complex interconnections. Using only the models of individual membrane stages and the topology of physical flow network, this paper establishes the stability, stabilizability and disturbance attenuation of the UF plantwide process with decentralized controllers.
