Research on the Renovation Practice of SIS System in the Supporting Tank Area of a Chemical Plant Project
In response to the lack of specialized safety instrument systems in the self built tank area of chemical plants,which all rely on DCS systems to achieve interlocking and protection,from the level of self-control to the safety requirements of the tank area,which are far from the current requirements,storage tanks with safety defects are gradually transformed into level instrument interlocking and valve rapid cut-off control systems.This renovation aims to establish an independent SIS system for primary and secondary major hazards in the oil tank area in accordance with relevant regulations,establish safety barriers,and ensure safe production.
