1. A method for detecting an abnormal situation associated with a reactor in a process plant, the method comprising:

  • calculating first statistical data from a pressure signal indicative of pressure within a vessel of the reactor, wherein calculating the first statistical data comprises calculating at least one of a mean of the pressure signal, a standard deviation of the pressure signal, a variance of the pressure signal, a root-mean square of the pressure signal, a rate of change of the pressure signal, a range of the pressure signal, a filtered pressure signal, and a correlation associated with the pressure signal;

    analyzing the first statistical data to detect whether one or more abnormal situations associated with an agitator of the reactor exist; and

    generating an indicator of an abnormal situation if one or more of the one or more abnormal situations are detected.
