Keeping an eye on the process

摘要

Apredictive maintenance policy uses process diagnostics and performance analysis tools to focus maintenance resources mainly on problematic loops and components offering the greatest return on investment. Surveys show there is considerable room for improvement in plant operations if the end user adopts an effective loop maintenance policy. This multi-industry loop audit survey reported only 32percent of loops have acceptable or excellent performance. With that poor loop performance in mind, there are industries out there right now adopting a form of condition based maintenance (CBM) as a predictive maintenance policy.
