Comprehensive Safety Evaluation On Hydrotreating Unit In Petrochemical Enterprises

With the increasing emphasis on safety production, government departments, more and more attentionto the safety evaluation, in order to provide technical support for production safety supervision andmanagement. Enterprises as the main production safety, and also more and more attention to the safetyevaluation, in order to improve the level of enterprise security management. Safety evaluation has a veryimportant role in the production of oil industry safety, is an important means to achieve safety in production,is effective in improving the safety of a basic work of the nature of the firm, is an important initiative toeliminate hidden dangers, and prevention of accidents.Refining enterprises are concentrated areas of high temperature and high pressure, flammable andtoxic and hazardous media, the risk is relatively large, the refining business through a comprehensive safetyevaluation, inspection, identification and analysis of all aspects of the refining unit production safetysystem, Find insufficient, problems and defects, and proposed the corresponding countermeasures andsuggestions to find the optimization of management methods and improved ways of enhanced the deviceproduction run of security, stability, and improve the safety level of production management is necessary.This subject use safety system engineering principles, human, machine, material, method, the variouselements of the ring established the refinery enterprise safety constituted by the five elements of thepersonnel, process, equipment, management, environment evaluation index systemthe use of expert pollmethod and AHP to determine the weights of the various elements, the use of a safety checklist, expertscoring, scoring competition exam, spot checks and other means of evaluation greatest degree seeks toevaluate the authenticity, and reliabledegrees, and then establish the evaluation set and fuzzy mathematicalmodel, the use of multi-level fuzzy comprehensive evaluation method to calculate and draw the evaluationfindings, and comprehensive safety evaluation Dalian Petrochemical Company of China Petroleumproduction New Area hydrogenation unit, for example, the results of the evaluation and the actualThesituation is more consistent.
