Abstract:
A plant or refinery may include equipment such as reactors, heaters, heat exchangers, regenerators, separators, or the like. Types of heat exchangers include shell and tube, plate, plate and shell, plate fin, air cooled, wetted-surface air cooled, or the like. Operating methods may impact deterioration in equipment condition, prolong equipment life, extend production operating time, or provide other benefits. Mechanical or digital sensors may be used for monitoring equipment, and sensor data may be programmatically analyzed to identify developing problems. For example, sensors may be used in conjunction with one or more system components to detect and correct maldistribution, cross-leakage, strain, pre-leakage, thermal stresses, fouling, vibration, problems in liquid lifting, conditions that can affect air-cooled exchangers, conditions that can affect a wetted-surface air-cooled heat exchanger, or the like. An operating condition or mode may be adjusted to prolong equipment life or avoid equipment failure.

Claim (Index 16):
The one or more non-transitory computer-readable media of  claim 15 , storing executable instructions that, when executed, cause the system to:\n receive first sensor data comprising first flow data measured by a first flow sensor associated with a first passage along a flow length associated with the heat exchanger, the first flow data associated with the first passage along the flow length associated with the heat exchanger; receive second sensor data comprising second flow data measured by a second flow sensor associated with a second passage along the flow length associated with the heat exchanger, the second flow data associated with the second passage along the flow length associated with the heat exchanger; determine whether a difference between the first flow data associated with the first passage and the second flow data associated with the second passage is greater than a threshold; and based on determining that the difference between the first flow data associated with the first passage and the second flow data associated with the second passage is greater than the threshold, determine that the vibration is occurring within the heat exchanger.
