摘　　要：对炼化装置的健康评价主要关注故障检测和故障诊断领域,这种技术仅能监测现场装置是否存在故障,难以发现装置在长期运行过程中可能出现的潜在异常或故障;为解决这一问题,提出了一种针对装置级别的健康度评价体系,该评价体系建立了包括工艺分组健康度、安全联锁健康度和能耗环保健康度3个方面的评价指标,进而计算出催化重整装置整体的健康度;将装置按级划分,并采用层次分析法确定各级权重,接着通过控制回路异常检测技术结合设定的打分规则,计算出工艺分组健康度;根据预警机制复现安全联锁系统,并分析能耗环保指标,得到装置整体评价结果;将文章提出的评价体系应用于某炼化厂催化重整装置,试验结果表明,该方法能够对催化重整装置进行定量和合理的评价。The health evaluation of refinery units mainly focuses on the fields of fault detection and fault diagnosis.This technology can only monitor whether there is a fault in field devices,but it is difficult to find potential abnormalities or faults that perhaps occur during the long-term operation of devices.To solve this problem,a novel device-level health evaluation system is proposed.The evaluation system establishes three evaluation indexes,including the process grouping health,safety interlock health and energy consumption and environmental health,so as to calculate the overall health of the catalytic reforming units.The reforming units are divided by all levels,the weighting of each level is determined by using the hierarchical analysis,and then the control loop anomaly detection technique combined with scoring rules is applied to calculate the process group health.The safety interlock system is reproduced according to the early warning mechanism,and the energy consumption and environmental protection indicators are analyzed to obtain the overall evaluation results of the devices.The proposed evaluation system is applied to a catalytic reforming unit in a certain refinery.Experimental results show that the method can provides a quantitative and reasonable evaluation of catalytic reforming units.
