Abstract: A monitoring and control system for a seal gas supply system for a non-contacting gas seal. The supply includes several gas conditioning elements or units. The monitoring and control system includes an evanescent wave sensor to sense the presence of liquid in the seal gas. Multiple sensors to sense the temperature and pressure of the treated seal gas are disposed at the outlet of the conditioning elements. A programmable logic device is provided with information regarding the phase of the gas at various pressures and temperatures and compares the sensed data to the baseline data. Recognition of liquid concentrate results in an output signal.

Abstract: A seal monitoring and control system for a gas lubricated non-contacting seal includes various sensors providing signals to a programmable logic control system. The control system is disposed to determine a presence of an anomalous operating condition of the seal, for example, based on phase, relative position of rotor to stator or other signals in combination provided by the various sensors to provide an output signal, which in one embodiment performs at least one mitigating process to correct the anomalous operating condition by adjusting at least one operating parameter of the seal.
