Abstract

A system for detecting abnormal situations associated with a reactor in a process plant receives statistical data associated with pressure within a reactor vessel. For example, a pressure sensor device disposed at least partially within the reactor vessel may generate the statistical data based on a pressure signal. The statistical data is analyzed to detect whether one or more abnormal situations associated with an agitator of the reactor exist. For example, the statistical data may be analyzed to detect whether the agitator is no longer turning, is turning at a rate that is different than expected, is out of balance, is broken, etc. If an abnormal situation is detected, an indicator of the abnormal situation may be generated.
