Methods and apparatus are disclosed for detecting and preventing compressor surge. A transmitter determines a derivative process value of a compressor. A controller obtains the derivative process value from the transmitter. The transmitter is separate from the controller. The controller compares the derivative process value to a threshold value. The threshold value is indicative of the initiation of a surge event in the compressor. In response to determining that the derivative process value fails to satisfy the threshold value, the controller actuates a valve operatively coupled to the compressor to enable an additional derivative process value of the compressor determined by the transmitter to satisfy the threshold value.

Systems and methods to monitor an asset in an operating process unit are disclosed. An example method includes monitoring one or more equipment parameters associated with an asset in an operating process unit, monitoring one or more process parameters associated with the asset, and determining an asset health value corresponding to the asset based on the one or more monitored equipment parameters, process parameters, and baseline data associated with the one or more equipment parameters.

Systems and methods to monitor pump cavitation are disclosed. An example method includes monitoring a pressure parameter and a vibration parameter associated with an asset in an operating process unit. The example method includes calculating a manipulated pressure value based on the pressure parameter. The example method includes calculating a manipulated vibration value based on the vibration parameter. The example method includes determining a state of cavitation associated with the asset based on at least one of the manipulated pressure value or the manipulated vibration value.
