20100276340 | IN-LINE SYSTEM FOR DE-SALTING FUEL OIL SUPPLIED TO GAS TURBINE ENGINES - An in-line system uses a simple static emulsifier to thoroughly mix salt-containing fuel oil with water, thereby to draw the salt from the fuel oil into the water preferentially, and then the de-salted fuel oil is separated from the salt-containing water. | 11-04-2010 |
20110163011 | USING SUPERCRITICAL FLUIDS TO REFINE HYDROCARBONS - This is a method to reactively refine hydrocarbons, such as heavy oils with API gravities of less than 20° and bitumen-like hydrocarbons with viscosities greater than 1000 cp at standard temperature and pressure using a selected fluid at supercritical conditions. The reaction portion of the method delivers lighter weight, more volatile hydrocarbons to an attached contacting device that operates in mixed subcritical or supercritical modes. This separates the reaction products into portions that are viable for use or sale without further conventional refining and hydro-processing techniques. This method produces valuable products with fewer processing steps, lower costs, increased worker safety due to less processing and handling, allow greater opportunity for new oil field development and subsequent positive economic impact, reduce related carbon dioxide, and wastes typical with conventional refineries. | 07-07-2011 |
20120298559 | METHOD FOR HYDROCARBON REMOVAL AND RECOVERY FROM DRILL CUTTINGS - The present invention relates to a system and a method for the extraction of hydrocarbons from drill cuttings in drilling mud. The system for extracting hydrocarbons from drill cuttings includes at least one extraction tank, a carbon dioxide tank fluidly connected to the at least one extraction tank, and at least one separation tank in fluid communication with the at least one extraction tank. The method for extracting hydrocarbons from drill cuttings consists of exposing the drill cuttings to liquid carbon dioxide, solubilizing hydrocarbons from the drill cuttings with the liquid carbon dioxide, heating the liquid carbon dioxide and the soluble hydrocarbons to convert liquid carbon dioxide to carbon dioxide vapor, separating the hydrocarbons from the carbon dioxide vapor, and collecting the separated hydrocarbons. | 11-29-2012 |
20140202929 | SYSTEMS AND METHODS FOR MONITORING AND CONTROLLING DESALTING IN A CRUDE DISTILLATION UNIT - Disclosed herein are systems and methods for automated real-time monitoring and controlling desalting in a crude distillation unit. Crude oil and wash water are mixed by a pressure drop across a mix valve, thereby forming a crude oil/water phase stream. The crude oil/water phase stream is supplied into a desalter vessel, whereupon an emulsion forms at an interface between the crude oil and the water phase. The crude oil/water phase stream is contacted with a dosage of an emulsion breaker in an applied electric field. At least one property associated with the emulsion is measured using an emulsion level indicator. A total chlorine and a water percentage of the crude oil are measured. At least one of the pressure drop and the dosage of the emulsion breaker is adjusted substantially in real time in response to at least one of the measured properties, total chlorine, and water percentage. | 07-24-2014 |
20140251874 | SEPARATOR FOR DESALTING PETROLEUM CRUDE OILS HAVING RAG LAYER WITHDRAWAL - An improved separator for desalting petroleum crude oils which may be operated in a continuous manner under automatic control; the improved desalter is therefore well suited to modern refinery operation with minimal downtime. A portion of the emulsion layer is withdrawn from the desalter through external withdrawal ports according to the thickness and position of the emulsion layer with the selected withdrawal header(s) being controlled by sensors monitoring the position and thickness of the emulsion layer. The withdrawn emulsion layer can be routed as such or with the desalter water effluent to a settling tank or directly to another unit for separation and reprocessing. | 09-11-2014 |
20140353214 | PETROLEUM CRUDE OIL DESALTING PROCESS AND UNIT - An improved method and process unit for desalting petroleum crude oils in which a portion of the stable emulsion layer which forms in the desalter vessel is withdrawn from the desalter and diluted with a liquid diluent, typically oil or water or both to destabilize the emulsion which is then separated into separate oil and water phases. | 12-04-2014 |
20150083644 | DESALTER EMULSION SEPARATION BY DIRECT CONTACT VAPORIZATION - 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. | 03-26-2015 |
20150144534 | SEQUENTIAL MIXING PROCESS FOR IMPROVED DESALTING - A process and system for desalting crude oil includes delivering a stream of salty crude oil and wash water into a mixing valve, mixing the stream of salty crude oil and wash water through the mixing valve to create a mixed stream of desalted crude oil and salty wash water, delivering the mixed stream of desalted crude oil and salty wash water to a static mixer, and mixing the mixed stream of crude oil and wash water in the static mixer. Within the static mixer, the mixed stream is mixed in a coalescing regime to coalesce smaller droplets of water into larger droplets of water. The mixed stream is then directed to a desalter where the salty wash water is separated from the desalted crude oil. | 05-28-2015 |
20150299581 | SYSTEM AND METHOD OF DELIVERING DILUTION WATER DROPLETS WITHIN AN OIL-AND-WATER STREAM - A system for desalting a crude oil stream includes an elongated, vertically oriented vessel that has an interior piping structure arranged concentric to the vessel. The piping structure, which may have more than one level, has a plurality of spray nozzles oriented at a downward angle for atomizing wash water into a downward flowing crude oil stream. The spray nozzles may be located on a same side or opposite sides of the piping structure. Where multiple levels are used, the number of spray nozzles on each level may be the same as or different than the number of spray nozzles on other levels. The pressure drop through each spray nozzle is preferably no greater than 300 psi and the nozzles preferably deliver a dilution water droplet preferably no larger than 300 microns in diameter. A mixing valve, static mixer, or both can be placed downstream of the vessel. | 10-22-2015 |
20160024395 | Method of Reducing Corrosion and Corrosion Byproduct Deposition in a Crude Unit - A method of optimizing system parameters in a crude unit to reduce corrosion and corrosion byproduct deposition in the crude unit is disclosed and claimed. The method includes measuring or predicting properties associated with the system parameters and using an automated controller to analyze the properties to cause adjustments in the chemical program to optimize the system parameters. Adjusting the system parameters effectively controls corrosion in the crude unit by reducing the corrosiveness of a fluid in the process stream and/or by protecting the system from a potentially corrosive substance. System parameter sensing probes are arranged at one or more locations in the process stream to allow accurate monitoring of the system parameters in the crude unit. | 01-28-2016 |
