Effective ways to improve safety instruments in petrochemical industry

1.4 Strengthen the corresponding management work

Although oil care enterprises have high requirements for instrument systems, and the state also has certain standard requirements for it, according to the actual application analysis of instrument systems, it is found that there are certain problems in the safety protection work of the system, actual operation and construction, or the cognition of risks in production, and it cannot meet people's requirements. For example, in the actual design of safety instrument system, during the design process, no scientific method is adopted in the calculation and estimation of SIF, which will cause problems in redundancy configuration. The main problems are reflected in fault tolerance. In this process, the guidance of design drawings and schemes is ignored only for the completion of the design, resulting in deviations and other situations in the construction. In this case, the safety performance of the instrument system will decline. Therefore, in order to ensure the stability, safety and reliability of the instrument system during operation, relevant managers should conduct comprehensive management of the instrument system, and formulate corresponding management plans for the implementation of management work. This ensures that the safety of the instrument safety system during operation can meet the requirements of the staff.

2 Safety instrument reliability fault-tolerant design

As far as the design of instrument system is concerned, if the petrochemical system is designed, the designer should protect the instrument tested by the instrument in advance, conduct a comprehensive analysis of the process behavior involved in the operation of the instrument, evaluate the overall safety, and make a detailed division of the safety instrument system according to the evaluation content [3]. In addition, if an instrument system with a low safety level is found in the process of analysis and evaluation, the design of the instrument system should be integrated into DCS at this time, so as to reasonably control the design cost of the system. In addition, for the loop with high failure rate, its application in production not only has a greater threat, but also has a direct impact on the production order. Therefore, the safety instrument system should be designed for the loop to realize the control of the safety performance of the loop and reflect the specific function of the loop. This provides guarantee for the safety and reliability of production.
