In order to increase the safety of chemical process

researchers proposed many methods and strategies

some quantitative indices have been developed to describe the potential hazard and dangerous of different reaction route and reactant.In this paper

the stability was considered as a factor to indicate the process safety

and a quantitative analysis of the capability of resistance to disturbance of stable steady-state points were conducted

then the fermentation process and MMA process were studied to demonstrate the effectiveness of the proposed method.
