Case Study of Online Safety Assessment on Atmospheric and Vacuum Catalysis of Distillation System and Pressure Vessel of Diesel Hydrogen Device Based on RBI Technology

摘要

The atmosphere & vacuum-catalytic cracking integrated unit of a petrochemical enterprise in Hangzhou can not be tested for continuously producing 35 sets of pressure vessels. This thesis assesses the three main parameters (probability of failure, failure result and risk of failure probability and result) of the system through FBI technology, analyzes the potential failure mode and probability in this system and confirms the risk of failure via calculating failure result. This thesis shows the testing strategy suitable for this device based on failure mode, failure probability and result and puts forward scientific and proper testing cycle based on risk level of equipment to ensure the depth and rationality of overdue testing work and improve the reliability of safe and stable operation of device for the system before the next maintenance cycle.
