Safety Instrumented System
Thread Content
The newly established fine chemical enterprise has 6 production processes, 2 of which involve processes that fall under the category of \"two key areas and one major risk\" – namely, hazardous chemical processes that require close monitoring, hazardous chemicals that need strict control, and medium to high-risk sources. In order to ensure successful approval during the inspection, the design firm designed 2 DCS control systems and 2 safety instrument systems. I was wondering whether this is really necessary; it seems like a waste of money!
Those involving \"two key points and one major issue\" must be carried out in full accordance with the regulations set by the Safety Supervision Bureau; otherwise, the inspection will not be approved.
Both DCS and SIS are necessary, but as for exactly how many sets to install, it is necessary to calculate the controller load; the designs prepared by design firms are generally reliable.
It must be installed; otherwise, there’s no need for a review. The poster still needs to install an emergency stop system; otherwise, it won’t pass either
Safety first – what needs to be spent must still be spent; P
Go ahead, follow the recommendations of the design institute – failing the safety inspections will only delay the project progress
Go ahead, I have no choice but to do it; I spent over ten million on a new exhaust treatment system
Is your focus on whether to go or not, or on how many sets to do? Regarding whether you need to go up or not, as already mentioned above, in order to pass the safety inspection, **per the regulations**, you must go up. As for the previous sets, it depends on the scale of these two production processes as well as their degree of interconnection. If the scale is small and the processes are closely linked, they can be integrated into one system with separate controllers; however, if the scale is large and the processes are not very interconnected, it’s better to keep them separate for easier management and operation
