Petrochemical Plant Accident Statistics And Risk Control System Development

Production safety of the Petrochemical industry, not only can affect the development ofthe national economy, but also is closely related to people’s life and property. Whether or notthe petrochemical industry can realize safety production, installations play a decisive role.Petrochemical plants have an high accident rate, due to its complex structures, poor workingconditions and generally dangerous process medium. In a time when computer technologyimproves rapidly, the application of risk control software in petrochemical production aregetting more attention from domestic and international petrochemical enterprises. Under thisbackground, in this context, his project is aimed at developing a software functioningstatistics of Petrochemical plants accidents and risk control, to reduce the occurrence ofPetrochemical plants accidents as well as the corresponding loss.This paper investigated a large number of research literatures at home and abroad aboutthe petrochemical plants’risk control and accident statistics. Based on these investigation andwith reference of existing risk control software, and in order to meet the demands of the riskcontrol of the petrochemical plants, a software functioning risk control of Petrochemicalplants has been designed and developed. Additionally, a reasonable database structure wasfigured out with consideration of related knowledge.This software system consists of five modules, system management, device information,safety assessment, safety education and accident cases. The accident cases module uses otherindustries’ accident database schema for reference. And by combination with thecharacteristics of the petrochemical plants, the suitable accidents classification methods andstatistics form for petrochemical units were decided. To make risk identification more logical,a combination of process flow diagram and detailed device information were used. Detaileddevice information includes operation condition, medium, hidden dangers and past accidents.Safety assessment module optimized the evaluation method and decided reasonable accidentresult simulation model on several basis, which includes: two most commonly usedassessment method (risk evaluation method, Dow Fire index method), and three accidentsconsequence analogy model (pool fire model, Boiling Liquid Expanding Vapor Explosion,vapor cloud explosion model). Safety education module is about mostly laws and regulation, standard and videos of typical accident case in production.FCCU(fluid catalytic cracking unit), the main equipment of the petrochemical units, isselected as a typical instance to test the function and role of the software, and it presented agood performance. This shows that the software system was able to carry out a reasonablerisk identification and safety assessment on the petrochemical plants and reduce accident rateas much as possible and losses to ensure the safety operation of the petrochemical plants.
