Patent number: 10392917Abstract: Identifying geographical uses, other than disposal for produced water that is recovered from a well and establishing methods and systems for recovering and handling this water. The produced water is treated so as to render the produced water suitable for solution mining. The produced water is transported to a solution mining site and the produced water is utilized at the solution mining site.Type: GrantFiled: November 15, 2017Date of Patent: August 27, 2019Assignee: AMEC FOSTER WHEELER USA CORPORATIONInventors: Katherine N. Zimmerman Frisby, Patti Yoast

Patent number: 10322371Abstract: Methods of sequestering carbon dioxide (CO2) are provided. Aspects of the methods include contacting an aqueous capture ammonia with a gaseous source of CO2 under conditions sufficient to produce an aqueous ammonium carbonate. The aqueous ammonium carbonate is then combined with a cation source under conditions sufficient to produce a solid CO2 sequestering carbonate and an aqueous ammonium salt. The aqueous capture ammonia is then regenerated from the from the aqueous ammonium salt. Also provided are systems configured for carrying out the methods.Type: GrantFiled: March 24, 2017Date of Patent: June 18, 2019Assignee: Blue Planet, Ltd.Inventors: Brent R. Constantz, Jacob Schneider, Mark Bewernitz

Patent number: 10213729Abstract: Method of decarbonating a hydrocarbon gas, a natural gas for example, by washing with a solvent. Said gas is contacted with an absorbent solution so as to obtain a CO2-depleted gas and a CO2-laden absorbent solution. The CO2-laden absorbent solution is then heated and expanded at a predetermined pressure and temperature so as to release a hydrocarbon-containing gaseous fraction and to obtain a hydrocarbon-depleted absorbent solution, said pressure and temperature being so selected that said gaseous fraction comprises at least 50% of the hydrocarbons contained in said CO2-laden absorbent solution and at most 35% of the CO2 contained in said CO2-laden absorbent solution. Finally, the hydrocarbon-depleted absorbent solution is thermally regenerated so as to release a CO2-rich gaseous effluent and to obtain a regenerated absorbent solution.Type: GrantFiled: May 19, 2014Date of Patent: February 26, 2019Assignee: IFP ENERGIES NOUVELLESInventors: Sebastien Gonnard, Nicolas Laloue, Agnes Leroy, Gauthier Perdu
