Patent number: 10619468Abstract: The invention relates to injecting steam into crude oil for several benefits, primarily of which is to remove salt by transferring the salt into the condensed water from the steam. Steam transfers salt via a different transfer mechanism and therefore doesn't require the high shear mixing of conventional water injection systems. As such, steam injection through a variety of procedures, is more efficient at gathering salt into water that itself is easier to remove from the crude oil.Type: GrantFiled: November 21, 2017Date of Patent: April 14, 2020Assignee: Phillips 66 CompanyInventors: Keith H. Lawson, Derek H. Willman

Patent number: 10315131Abstract: A method for preparing a crude oil solution for analysis, including adding water to a porous adsorbent to obtain a supported water substrate, having a plurality of water monolayers disposed on the porous adsorbent. The method further includes exposing the crude oil solution to the supported water substrate for a period of time; separating the supported water substrate from the crude oil solution; washing the supported water substrate with a water immiscible solvent to remove at least one hydrocarbon; displacing water from the plurality of water monolayers and the at least one interfacially active compound from the porous adsorbent with an alcohol and a co-solvent to obtain a displaced phase. The displaced phase can include the water, the at least one interfacially active compound, the alcohol, and the co-solvent. Finally, the method can include drying the displaced phase to isolate the at least one interfacially active compound.Type: GrantFiled: October 22, 2013Date of Patent: June 11, 2019Assignee: FLORIDA STATE UNIVERSITY RESEARCH FOUNDATION, INC.Inventors: Jacqueline M.

Patent number: 9957172Abstract: Various embodiments provide methods for removing a PFC by concentration and separation. In an exemplary method, a PFC in an aqueous solution or in a mixed water-organic solvent solution can be adsorbed onto a surface of a floc generated by electroflocculation, to form sludge. The sludge containing the PFC can be centrifuged to separate the PFC from the sludge and to form a concentrated PFC solution. Eelectroflocculation provides a simple process that is easy to operate. Reaction conditions are mild. Energy consumption is low. Treatment effect is desirable, stable, and reliable. Industrial application can be easy to implement. Further, the centrifugal separation technology used for the harmless treatment of the generated PFC-containing sludge is novel and does not need to use chemicals. Further, dewatering of the sludge is achieved at the same time during the harmless treatment. The needed equipment is simple and can be automatically operated.Type: GrantFiled: April 18, 2014Date of Patent: May 1, 2018Assignee: BEIJING NORMAL UNIVERSITYInventors: Junfeng Niu, Hui Lin, Qingguo Huang, Zhifang Chen

Patent number: 6299780Abstract: A method for treating silicone emulsion waste includes the steps of adding base chemical materials to the silicone emulsion waste in an amount effective to cause separating of the silicone emulsion waste. The added chemicals separate the silicone emulsion waste into silicone oil and an emulsion-free water. The components can be separated, with the silicone oil laden liquid being recycled and the emulsion-free water being sent to a wastewater treatment plant. The base chemicals can include sodium hydroxide, sodium carbonate, sodium chloride and/or combinations thereof. To enhance separating of the silicone emulsion waste, the silicone emulsion waste can be heated prior to the addition of the chemicals. Also, by recycling the treated water and adding the same to the silicone emulsion waste and base chemicals separation of the silicone emulsion waste can be enhanced.Type: GrantFiled: December 20, 1999Date of Patent: October 9, 2001Assignee: General Electric CompanyInventors: Amy Rene Freshour, Bang Mo Kim, Roy Fred Thornton
