危险度评价法在重整装置中的应用

为了确定重整装置中可能导致重大事故的基本原因,并有针对性地采取安全措施,运用危险度评价法对重整装置进行安全评价。通过危险性分析,发现了装置的安全隐患,并利用危险度评价表划分了设备单元的固有危险等级。结果表明,装置具有很高的固有危险等级,且含有大量危险物质,其中多数设备因为温度压力过高、腐蚀破裂等因素极易导致介质泄漏,从而引发火灾、爆炸事故。根据评价结果,提出相应的安全对策,预防此类事故的发生,保证生产平稳运行。

Application of Risk Degree Assessment Method in Reforming Unit

In order to determine the basic causes of major accidents which may occur in the reforming unit, and take the countermeasures of safety, this paper used the risk degree assessment method for safety assessment about the reforming unit. Hidden danger of the unit was found by the analysis of risk, and intrinsic risk grades of the equipment units was divided by the risk assessment table. Results show that the unit has very high intrinsic risk grade, in which the existence of a large number of hazardous substances, most equipments because of the high temperature and pressure, corrosion and other factors can easily lead to the leakage of medium, so as to cause fire and explosion. According to the results of the assessment, propose the corresponding safety measures to prevent accidents, ensure the production running smoothly.
