Does anyone know the sequence for shutting down petrochemical units in reverse order? Which unit should be shut down first, and which one afterwards?

I’d appreciate it if an expert could reply. Thank you so much!
"The topic of \"refining and chemical processing units\" is too broad; it depends on the technical approach adopted for such units. For example, there are oil refining routes, olefin routes, and aromatic routes. The oil refining route can further be divided into hydrogenation routes or coking routes, and so on. You can introduce what devices are included in your “refining unit” and what its scale is, or you can post a block diagram of your unit’s process flow.
Your question is of a godly level; ordinary people can’t answer it
