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.

Seal monitoring and control system

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.

Seal gas monitoring and control system

A system of conditioning elements is described for supply of conditioned seal gas to the seal chamber of a rotary machine employing gas lubricated, non-contacting seals. It includes elements to remove particulate solid and liquid and volatile components from the gas and to heat the gas to a predetermined level. It also includes an element to amplify the pressure of the gas. The pressure amplifier is operative in response to a condition of the gas to be supplied to the seal chamber, to ensure that an adequate supply of seal gas is available. The system of conditioning elements may be assembled onto a single skid.
