20140290357 | SYSTEM AND METHOD FOR IDENTIFYING LEVELS OR INTERFACES OF MEDIA IN A VESSEL - 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. | 10-02-2014 |
20150027849 | METHODS AND SYSTEMS TO REMOVE POLAR MOLECULES FROM REFINERY STREAMS - The present invention relates to methods and systems for removing polar molecule contaminants from a refinery stream in connection with the processing of hydrocarbon fluids, chemicals, whole crude oils, blends and fractions in refineries and chemical plants that include adding high surface energy and/or high surface area nanoparticle compounds to a refinery stream to remove the polar molecule contaminants. | 01-29-2015 |
20150059368 | UTILIZATION OF WASTE HEAT USING FIBER SORBENT SYSTEM - A method for creating work by adsorption end desorption of a working fluid on an fiber sorption system which has a plurality of tubular hollow fibers within a vessel which is connected to a work device. Each fiber is in the form of a tubular, elongated body composed of a sorbent material capable of adsorbing a working fluid such as carbon dioxide. The fibers have an inner surface adjacent the hollow interior and an outer surface, one of which has a coating layer which is impermeable to both a working fluid and thermal fluid. The system is operated by passing a thermal cooling fluid in contact with the fibers to cool the fibers and passing the working fluid over the fibers in contact with the surface of the cooled fibers which does not have the coating layer so that the working fluid is adsorbed on the fibers, the adsorbed working fluid is then desorbed from the fibers by passing a thermal heating fluid in contact with the fibers to heat the fibers; the pressurized, desorbed working fluid is then passed to a work device connected to the vessel. | 03-05-2015 |
20150152340 | DESALTER EMULSION SEPARATION BY EMULSION RECYCLE - A petroleum desalting process in which fluid from interfacial boundary layer between the settled water layer and the settled oil layer or emulsion-water layer in the vessel is withdrawn from the desalter and recycled to the crude oil inlet of the desalter to improve separation of the oil and water phases. | 06-04-2015 |
20150175904 | DESALTER OPERATION - A petroleum desalting process in which the role played by the oil/bulk-resolved-water interface in the dehydration of the stabilized emulsion which forms in the desalter is recognized. The desalting process is improved by introducing the demulsifier and chemical high voltage electrodes. Water droplets in the mixture coalesce and settle towards the bottom of the vessel. A stabilized emulsion layer formed from the oil and the water with additives into the water phase and/or injecting chemical additives directly in the vicinity of the water/oil interface. This improved methodology that makes the rapid and effective delivery of chemical demulsifiers to the rag layer and/or oil/bulk-resolved-water interface possible. In operation, the desalting is carried out by mixing a crude oil to be desalted with water and passing the mixture of oil and water to the desalter vessel. The mixture enters the desalting vessel in the form of an emulsified mixture which is then separated by application of an electric field between emulsion-stabilizing solids from the oil forms above the interface between the denser water layer and the supernatant oil layer. A chemical demulsifier is added to the water layer in the region of the stabilized emulsion layer and/or directly into the emulsion layer itself. The separated water is removed as effluent through a water outlet at the bottom of the vessel and desalted oil is removed from the oil layer through an oil outlet at the top of the vessel. | 06-25-2015 |
20150267127 | DESALTER OPERATION - A petroleum desalting process is improved by introducing the an alkaline compound such as sodium carbonate into the water phase, preferably in the vicinity of the water/oil interface which forms between the oil and water layers. This makes the rapid and effective separation of the oil and water phases from the emulsion layer possible. | 09-24-2015 |
