摘要:
A petroleum desalting process in which the oil/water emulsion layer which forms in the desalter vessel between the settled water layer and the settled oil layer is separated into the oil and water components by contact with a heated high boiling hydrocarbon to break the emulsion and vaporize water from the emulsion in a flash drum. The vessel has an emulsion outlet for removing an emulsion stream from the emulsion layer and a conduit connecting the emulsion withdrawal port to an inlet of an optional settling drum to effect and initial separation into an oil-enriched phase and a water phase with the oil-enriched phase led to the flash drum.

摘要:
Systems and methods for detecting a deposit in a vessel with a sensing cable including an optical fiber sensor array aligned with a heating element disposed in the vessel. An excitation source is configured to propagate at least one heat pulse through the heating element along at least a portion of the sensing cable to affect an exchange of thermal energy between the heating element and media exposed to the sensing cable. An optical signal interrogator is adapted to receive a signal from a plurality of sensor locations and configured to measure, a temperature profile corresponding to the heat pulse at the sensor locations. A control unit is configured to detect a deposit by determining one or more properties of the one or more media exposed to the sensing cable at each of the plurality of sensor locations based on the temperature profile corresponding thereto.

Systems and methods for detecting coking in a wash bed of a vacuum pipe still with a sensing cable including an optical fiber sensor array aligned with a heating element disposed in the vessel. An optical signal interrogator is configured to measure a first temperature profile at a plurality of sensor locations to determine a flow distribution. An excitation source is configured to propagate at least one heat pulse through the heating element and the optical signal interrogator is configured to measure a second temperature profile corresponding to the heat pulse at the sensor locations. A control unit is configured to detect coking by determining one or more properties of the media exposed to the sensing cable at each of the plurality of sensor locations based on the second temperature profile corresponding thereto.
