Model-based Compressor Diagnostics
PROGNOST®-Genuit offers reliable machine diagnostics based on a mathematical compressor model that utilizes only current process data. The benefits of this tool are obvious, namely the process control system’s ability to monitor temperatures, pressures, and rotation speed of every process-critical reciprocating piston machine. The powerful PROGNOST®-Genuit diagnostics tool uses these few very important parameters to help you achieving significant cost savings.
Users also enjoy the benefits of an extended Early Failure Detection period, even under varying operating conditions, thanks to continuous monitoring and an increase in the MTBM (MeanTime Between Maintenance) interval.
PROGNOST®-Genuit transmits the current process data in real-time to a theoretical compressor model. This model calculates temperature and pressure setpoints in relation to operating conditions. The calculated setpoints are compared with measured DCS actual values. A deviation (residuum) is provided with thresholds and displayed as a trend. Threshold violations are sent as plain text messages to users, and include a damage category. A damage category contains information about the affected component and the affected cylinder /compression chamber. In addition, the extent of the damage and the damage probability are shown as percentages. Providing information, not just data.
PROGNOST®-Genuit provides reliable monitoring of all suction and discharge valves, piston rings, stuffing-box packings, and gas cooler functions.
Mandatory field sensors
PROGNOST®-Genuit provides automatic diagnosis for:
- suction/discharge valves
- piston sealing rings
- stuffing box
- gas coolers
The system uses existing 4 – 20 mA sensors through a DCS-link.
