Regarding the setup of the DCS system
Thread Content
Dear experts, is it mandatory to install a DCS for major hazard sources of level 1 and 2? Which standards and specifications have explicit requirements? Thank you! ! !
Are there clear requirements specifying that DCS isolation valves must be installed on the inlet and outlet pipes?
It’s not a question of whether DCS needs to be installed in major hazard sources of level 1 or 2; rather, it’s about how full-process automation can be achieved without such a DCS control system. Chemical storage areas involving major hazard sources of level 1 and 2 should also be equipped with independent safety instrumented systems and emergency shutdown systems. Take a look at documents such as the three-year action plan for ** or the relevant region, as well as the criteria for identifying major accident hazards in hazardous chemicals enterprises.
