In the summer is hot and rainy, chemical plant a pressure swing adsorption system program control valve failure, aiming at the hidden trouble of equipment, workshop organization and operation, maintenance personnel held emergency drills, drill to a pressure swing adsorption control valve tower 3 valve is bad, resulting in vacuum pump import and export pipeline plate mats stuffy washed rotten, leak hypothesis, maintenance personnel in the treatment of electrostatic ignition and the accident for emergency treatment.
July 23 afternoon 4 when 20 points, with workshop leader "walkthrough" issued a password, participating personnel act quickly. Operating personnel immediately on PSA do stop processing, and always pay attention to the synthesis of system pressure changes, promptly contact the scheduling and increase the hydrogen pressure and concentration, in order to maintain normal production and control process is stable. Subsequently, the squad leader to inform the workshop management, and contact the maintenance workers to deal with. Maintenance workers rushed to the scene, in dealing with mat, due to the use of iron tapping valve spark, resulting in hydrogen ignition secondary accidents. The operator quickly launched the emergency plan, fire treatment, to avoid further expansion.
The whole exercise process, the division of labor is clear, with the tacit understanding, processing methods and timely and effective, the workshop management personnel to watch the exercise process. Drill test the operation and maintenance personnel to deal with the emergency response capacity, achieved good results.
