Safe dynamic health assessment method and assessment system for ethylene production

Abstract

The invention discloses a safe dynamic health assessment method and assessment system for ethylene production. The system comprises a monitoring center. The system is characterized in that the monitoring center is communicatively connected with an internal memory database; the internal memory database is communicatively connected with a real-time database; and the internal memory database is provided with an alarm management module, a failure plan database management module, a parameter information management module, a sensor validity analysis module, an abnormal condition identification module, a process monitoring module, an SDG modeling module and a historical data recording module. The safe dynamic health assessment method comprises the steps that a device safety and health comprehensive index assessment model is established; through threshold judgment and feature extraction of key safety technology parameters, feature matching with established process safety and health comprehensive indexes is carried out; KPI and historical statistical data are combined for production process safe dynamic health intelligent assessment and early warning; device fluctuations are minimized to ensure safe and smooth operation of a device.

Description

technical field [0001] The invention relates to the field of ethylene production, in particular to a safety dynamic health assessment method and an assessment system for ethylene production. Background technique [0002] Safety accidents in the petrochemical production process have the characteristics of strong concealment and many factors involved. The equipment operators only rely on single-point alarm information and personal operating experience to judge the safety and dynamic health status of the production process. Once a problem occurs, it is difficult to quickly and accurately find out. root cause, and take reasonable emergency measures, resulting in danger or even accidents. Therefore, the accurate assessment and early warning of the dynamic health status of process safety is an urgent problem to be solved. There are many uncertain factors affecting the production of petrochemical production equipment. The raw materials used in actual production, operating conditio...

Problems solved by technology

There are many uncertain factors affecting the production of petrochemical production equipment. The raw materials used in actual production, operating conditions and product structure may change compared with the design. Changes in these uncertain parameters often make the actual working conditions far from the design working conditions , so that the operation of the system cannot well meet the constraints of the production process. Once out of control, it will lead to accidents and even major disasters

[0003] The key issues are: (1) Safety accidents in the production process are highly concealed and involve many factors. It is difficult for plant operators to quickly and accurately find the root cause, which may cause misjudgment of the cause of the accident, and not only cannot be targeted accident handling, it may also cause derivative accidents
