Operability for Processes with Recycles: Interaction between Design and Operation with Application to the Tennessee Eastman Challenge Process

摘要: In this work, a complex process with recycles, Tennessee Eastman Challenge Process, is studied to explore the operability for plants recycles. A simplified model constructed provide physical insight into plantwide process. The results show that composition distribution in reactor (or recycle flow rate) plays an important role determining optimal operating condition, i.e., achieving maximum one-pass conversion. trajectory of these points at different production rates employed construct policy (OOP). From OOP, input multiplicity observed plant Therefore, care has be taken also indicates inherent constraint on rate imposed by process, e.g., constraint. However, design control system may lead even more limited operability. Moreover, OOP can used evaluate a...
