Research progress of chemical process stability analysis

Chemical processes may experience a large number of disturbances. Stability is a key of chemical process operability, related to product quality and process safety directly. It is a criterion to determine whether a process can return to its original operating point when disturbance disappears. The research on stability can help to understand and adjust the nonlinear behaviors in chemical processes, such as multiple steady state and oscillation. Therefore, with the consideration of stability analysis, the chemical processes can be operated smoothly and safely under disturbance for a long time. This review concludes the progress in stability analysis from four aspects: multiple steady state and stability analysis, optimization with guaranteed stability, dynamic behavior adjustment of chemical processes, and stability analysis under uncertainty.
