【摘要】 反应-再生装置是渣油催化裂化的核心部分。反应器的性能改变会直接影响产品的质量。在一个工业过程中,一般的故障都是自然或者突然产生的。大量的研究论文都致力于监测的突然故障,但发现早期故障也很重要,因为它们特点是缓慢的动态变化,最终会导致更严重的问题。建议使用的方法称为CUSUM-PCA,与传统的PCA方法相比较具有早期故障检测功能以及高级过程监控的特点。结果表明,使用CUSUM-PCA方法比传统的PCA方法提前一个小时检测出异常。更多还原

【Abstract】 The reactor–regenerator is the heart of the RFCC unit. Change in the performance of the reactor directly influences product quality. Usually faults in an industrial process can either be abrupt or incipient in nature. Significant number of research papers have been dedicated to the monitoring of abrupt faults but uncovering incipient faults is also important, as they are characterized by their slow dynamic change that eventually leads to a more serious problem. The use of a proposed method known as CUSUM-PCA is compared with conventional PCA for its early fault detection features and advanced process monitoring characteristics. Results show that the proposed CUSUM-PCA provides abnormal situation detection over an hour in advanced than conventional PCA.更多还原
