Production control in ethylene plant

A theoretical basis for cell deaths

“…For such questions, control theory provides powerful tools to analyze the controllability of the system. The controllability of chemical reaction systems has been studied widely in both industries and academia [3][4][5][6][7][8][9]. The purpose of the chemical processes control is usually the stable running of the chemical plant at the economically optimal state using on-line optimization [3][4][5].…”

In such frameworks, the supply and drain of chemicals, temperature, and pressure are control inputs.…”

“…Depending on how the null-reaction manifolds intersect, the number of the direction subset changes. At most, there are 2 R direction subsets for a model with R reactions 5. In the followings, we assume the transversality of the intersections between ξ(t) and M i .…”
