After several unplanned outages during a period of less than 45 days of the two redundant turbo-pumps in a big chemical plant in Belgium, Emerson and local reliability partner I-Care where contacted in order to propose a solution. Since these pumps are having a crucial impact on the production throughput of the plant, the case had to be handled with highest priority and precision. In order to make a suitable solution we advised to execute locally a root cause analysis test with the Emerson portable online analyzer. By the results of this analysis the root cause of the unplanned failures was uncovered. The combination of certain process circumstances and the product quality itself where causing at certain moments heavy cavitation with high vibrations, serious wear-out and integrity distortion at both pumps as result. Based on this analysis, the company decided to install a fixed online condition monitoring system of Emerson to have better insights and control of their process circumstances in order to avoid abnormal ware of their critical turbo-pumps.
