Control Valve Fault Detection Based on Acoustic Emission Signal

Abstract:

The control valve is one of the fundamental components in the process control industry. It controls the flow rate of elements whether in the form of liquid or gas. The current method of control valve monitoring is done according to schedule. This requires the whole system to be shut down, and leak tests are done while the control valves are fully closed. This research attempts to find faults even while the control valve is open. Severe damage of the control valve would interrupt process which in turn could lead to plant breakdown. If this occurs, production would be interrupted. This problem motivates this research towards early detection of control valve fault. Acoustic emission (AE) method is one of the popular techniques for fault detection. This project applies the AE technique to monitor control valves’ leakage in several stages of damage; minor damage, critical damage, damaged and severe damage.
