摘要： Systems and methods for identifying the level of media 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 the one or more media exposed to the sensing cable. An optical signal interrogator is adapted to receive a signal from each of a plurality of sensor locations and measure a temperature profile corresponding to the heat pulse at the sensor locations. A control unit is configured to identify a level of each of media by determining properties of the media exposed to the sensing cable at each of the sensor locations based on the temperature profile corresponding thereto.

摘要： Systems and methods for detecting a condition of multi-phase flow through a component with a first sensing cable having a first sensor location and aligned with a heating element and a second sensing cable having a second sensing location a predetermined distance from the first sensing location. A heat pulse is propagated through the heating element. A first temperature profile at the first sensing location and a second temperature profile at the second sensing location, each corresponding to the heat pulse, are measured over time. A flow velocity is determined by correlating the first temperature profile with the second temperature profile. A condition of flow of the media is detected by determining a phase of at least one medium exposed to the sensing cable at the first sensing location based on the first temperature profile and the determined flow velocity.

摘要： Methods for determining the fouling propensity of a hydrocarbon stream and for reducing fouling are provided. In one method, the fouling propensity of a hydrocarbon stream is determined by obtaining a parameter value indicative of the fouling propensity at no less than two different temperatures, and an activation energy of fouling by the hydrocarbon stream is derived therefrom. In another method, the thus obtained parameter value at no less than two different temperatures and the activation energy are used to select proper heating fluids and operating temperature and to determine whether to add an antifoulant to the hydrocarbon stream to reduce fouling at a given temperature.

摘要： Targeted application of anti-fouling mechanisms in a heat exchange system produces higher rates of energy recovery. The anti-fouling mechanisms with high mitigation rates can be deployed at only the hottest portions of a pre-heat train that experience the highest rates of fouling and heat loss. In application, bundles of corrosion resistant smoothed tubes are deployed in the late pre-heat train to significantly reduce the formation of harder deposits. Vibration can be used as an adjunct approach in conjunction with the corrosion resistant, smooth tubes, or deployed alone on existing bundles. The use of high performing, more durable exchangers in select locations justifies the increased cost of these components.

摘要： A use of a foulant collector in a vessel or conduit in a paraffinic froth treatment (PFT) process. The foulant comprises asphaltenes. The foulant collectors are purposed to reduce build-up in the vessel or conduit and/or to reduce downstream foulant carry-over in the process. The surface of the foulant collectors may have an average water contact angle of less than 90 degrees. Additionally, together with such foulant collectors, a fluorocarbon polymer may be used as a surface of a vessel or conduit in the PFT process, for reducing fouling.
