Patent number: 9630141Abstract: A natural gas stream is passed through a single membrane element that is fabricated with two or more distinct types of membrane fibers. The membrane fibers have different characteristics in order to reduce the number of membrane elements required for gas separation and to improve gas separation performance due to changing gas composition because of permeation as the gas travels through the membrane element.Type: GrantFiled: February 16, 2010Date of Patent: April 25, 2017Assignees: Cameron Solutions, Inc., Petronas Carigali Sdn BhdInventors: Richard D.

Patent number: 9630122Abstract: A system for removing salt from a process stream being fed into a flash separator introduces a swirling motive fluid into the fluid column of the separator. The swirling motive fluid comes into contact with salt components residing in the fluid of the column to create a salt slurry. Means to limit the upward movement of the swirling motive fluid can be provided. The salt slurry is then removed and can be sent to a brine generation vessel. Saturated brine from the vessel is transported back to the fluid column to replace the motive fluid in the column.Type: GrantFiled: February 29, 2016Date of Patent: April 25, 2017Assignee: Cameron Solutions, Inc.Inventors: Joseph Min-Hsiun Lee, Gary W.

Patent number: 9522865Abstract: A system for, and method of, recovering salt from fluid stream in a recycle loop of a flash separator has a desanding hydrocyclone located in the hot recycle loop of the flash separator; a first solids fluidization device located at the bottom end of the flash separator's brine column; a second desanding hydrocyclone arranged to receive a salt slurry stream created by the first solids fluidization device; and an accumulator located downstream of the second desanding hydrocyclone and having a second solids fluidization device located at its bottom end. Each solids fluidization device causes a motive fluid to exit the device in a swirling motion to fluidize the salt components contained in the resident fluid. The overflow from the second desanding hydrocyclone is the motive fluid for the brine column and a produced water, condensate water, or seawater stream is the motive fluid for the accumulator.Type: GrantFiled: October 5, 2015Date of Patent: December 20, 2016Assignee: Cameron Solutions, Inc.Inventors: Joseph Min-Hsiun Lee, Gary W.

Patent number: 9505990Abstract: 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.Type: GrantFiled: April 18, 2014Date of Patent: November 29, 2016Assignee: Cameron Solutions, Inc.Inventors: Gary W Sams, Joseph Min-Hsiun Lee

Patent number: 9469585Abstract: A system and process for removing divalent ions from a MEG feed stream is presented. The system includes a chemical treatment tank where chemicals are mixed with the feed stream to form insoluble carbonate and hydroxide salts. The system also includes a membrane-type solid-liquid separation unit that receives the feed stream from the chemical treatment tank and separates it into a filtrate containing MEG and a retentate containing the insoluble salts. The system may also include washing the retentate to remove additional MEG, which is then recycled to a MEG regeneration or reclamation process. The system may also include a dryer that receives waste slurry from the solid-liquid separation unit and dries it to form a solid waste, thereby facilitating its handling, storage, and disposal.Type: GrantFiled: September 14, 2015Date of Patent: October 18, 2016Assignee: Cameron Solutions, Inc.Inventors: Bryan A.

Patent number: 9272972Abstract: A system for removing salt from a rich mono ethylene glycol (MEG) stream being fed into a flash separator isolates the fluid residing in the brine column of the separator from the MEG and introduces a swirling motive fluid into the column. The swirling motive fluid comes into contact with salt components residing in the isolated fluid of the column to create a salt slurry. The salt slurry is then removed and sent to a brine generation vessel. Saturated brine from the vessel is transported back to the column to replace the motive fluid in the column.Type: GrantFiled: June 17, 2014Date of Patent: March 1, 2016Assignee: Cameron Solutions, Inc.Inventors: Joseph Min-Hsiun Lee, Gary W.

Patent number: 9216934Abstract: A lean MEG stream having a first pH level is contacted with a CO2-rich gas stream to yield a lean MEG product having a second different and lower pH level preferably in a range of 6.5 to 7.0. The system and method can be readily incorporated into a slipstream MEG recovery package, with a source of the lean MEG stream being a MEG regeneration section of the package. The CO2-rich gas could be a vented CO2 stream from the MEG reclamation section of the package. Unlike hydrochloric and acetic acid overdosing, CO2 overdosing of the lean MEG stream does not lead to rapid acidification of the lean MEG product to be stored or injected.Type: GrantFiled: September 29, 2014Date of Patent: December 22, 2015Assignee: Cameron Solutions, Inc.Inventor: Brian E.

Patent number: 9023213Abstract: A method for treating an interface rag includes the steps of removing a volume of rag at a controlled rate from an upstream rag source and passing the rag through a high pressure pump and a heater. The heater heats the rag to a temperature of at least 350° F. to thermally decomposing any chemicals that had been added to the interface rag to promote separation. Diluent is then mixed with the heated rag to cool the rag to a temperature less than 300° F. and produce a 30 API rag. The cooled diluted rag is then treated in an electrostatic treater or sent directly to a hydrocyclone cluster. The electrostatic treater is preferably a vertical electrostatic treater with a conical-shaped lower portion and a means for agitating the solid-laden water within the treater to prevent the solids from settling on the bottom of the treater.Type: GrantFiled: May 1, 2009Date of Patent: May 5, 2015Assignee: Cameron Solutions, Inc.Inventor: Gary W.
