摘　　要：反应 再生系统是影响催化裂化装置安全运行和经济效益的关键因素 ,文中建立了失效模式、效应和危害度分析故障树分析方法 (FMECA) ,并将FMECA与故障树分析模型 (FTA)结合起来 ,深入分析了反应 再生系统操作工艺失常状态及设备的可靠性。获得引起反应 再生系统非正常运行状态的关键影响因素和薄弱设备的危害度。并根据失效模式和危害度的特点 。Reactor-regenerator system (FCCU) is the key effect factor on economic results of safety running for catalytic cracking unit. Fault modes, effect and criticality analysis (FMECA) were established, and the approach of FMECA combined with fault tree analysis (FTA) was used to analyze the reliability and unusual operating process of Reactor-regenerator system. The most important effect factors on operating process and criticality of most dangerous equipment were found. Based on the characteristics of failure modes and jeopardizing criticality of equipment, the theoretical instruction of how to prolongate the FCCU service term was proposed.
