Accident Consequences Simulation Of Debromination Hydrogenation Reaction

In the chemical industry production process, most of the raw materials and intermediateproducts have hazardous properties explosive, flammable, etc. In the same, the chemical rawmaterials that production, storage and transportation are often accidental leak. It causeseconomic losses, personal injury and equipment damage. Debromination hydrogenationprocess that in the chemical production process is widly.The process involves first batch ofkey regulators of dangerous chemical process and is an exothermic reaction with highreaction temperature and pressure. While the raw materials such as hydrogen, ethanol, nickeland other chemical substances have explosion and flamme. If leakage occurs, it will causeexplosions, fires and other accidents. Leakage will cause huge losses and there are some flawsin the enterprises administration, so debromination hydrotreating reaction kettle simulationcalculation of accident consequences is necessary.First，become familiar with the diffusion model, the vapor cloud explosion model, boilingliquid expanding vapor model, pool fires model etc. According to5m3Debrominationhydrotreating reaction kettle of Zhejiang Provice Pharmaceutical Co. Ltd. Select theappropriate consequences of the accident debrominated hydrogenation process model thatcombers enterprises reaction kettle parameters and natural condition.Secondly，ethanol leakage is mainly consideration to debromination hydrogenationreaction kettle leak. Analyze the concentration of diffusion, the main contents include：theaxial ground point maximum concentration calculation，certain moment of cloud state，theaxial distance downwind that the impact of the any concentration of the source of leakagemaximum. The concentration calculation is compared with the ethanol explosion limits andidentify limit of the axial distance and leaking outside time.Findly， the research is based on VB program and simulated fire and explosionprogramming. The main model: boiling liquid expansion vapor explosion model, vaporexplosion model, pool fire. Combining the results of these models with corporate general planthat is more conducive to the management of the incident reference simulation results forcompanies and reduce personal injury and reduce property damage.Through the research above，this thesis will provide enterprises emergency decisionguidance. It can reduce property damage, personal injury, mechanical damage and so on.Research conclusion of this thesis can provide the consequences of accidents to the EHSdepartment value.
