炼油装置运行周期评估技术及应用

Operation Cycle Assessment Technology for Refinery Units and its Application

炼油装置运行周期评估技术通过统计、分析装置故障数据,计算特定时间段装置的可靠性,进而获得装置可靠性随时间的变化规律和装置可靠性最差设备排序。介绍了该技术在某常减压装置的应用,应用结果表明,该评估技术为科学确定炼油装置运行周期提供了决策依据。

Through the statistics and analysis of the fault data,the reliability of the device in a specific period of time can be calculated.The variation rule of the reliability of the unit with time and the ranking of theworst equipment for device reliability can be obtained,so as to determine the operation cycle of the refining unit.The application of the technique in an atmospheric-vacuum distillation unit is introduced.The evaluation technique provides a basis for determining the operating period of the refinery unit scientifically.
