Patent number: 9309474Abstract: The method allows to incorporate an alcohol or a mixture of alcohols into fuels by minimizing the energy expenditure linked with the prior production of the alcohol or of the mixture of alcohols. One or more bases of the fuel, to which an oxygen-containing compound or a mixture of oxygen-containing compounds have possibly been added, are used to extract the alcohol or the alcohol mixture contained in aqueous solutions produced by biomass fermentation processes. After adjusting the temperature of the aqueous solution stream and of the stream containing one or more bases of the fuel through exchangers, these streams are fed into an extractor. The extract leaving the extractor is then dried and/or an oxygen-containing compound or a mixture of oxygen-containing compounds is added thereto. The raffinate leaving the extractor is sent to a water treating plant or recycled.Type: GrantFiled: June 26, 2008Date of Patent: April 12, 2016Assignee: IFP Energies nouvellesInventors: Frederic Augier, Cecile Barrere-Tricca, Arnaud Baudot, Pierre Boucot

Patent number: 7470829Abstract: The natural gas arriving through pipe 1 is deacidified by being brought into contact with a solvent in column C2. The solvent charged with acid compounds is regenerated in zone R. The purified gas evacuated by pipe 9 includes some of the solvent. The method enables the solvent contained in the purified gas to be extracted. In zone ZA, the purified gas is brought into contact with a non-aqueous ionic liquid whose general formula is Q+ A?, where Q+ designates an ammonium, phosphonium, and/or sulfonium cation, and A? designates an anion able to form a liquid salt. The solvent-impoverished purified gas is evacuated through pipe 17. The ionic liquid charged with solvent is regenerated by heating in an evaporator DE. The solvents separated from the ionic liquid in evaporator DE are recycled.Type: GrantFiled: February 14, 2005Date of Patent: December 30, 2008Assignee: Institut Francais du PetroleInventors: Renaud Cadours, Fabrice Lecomte, Lionel Magna, Cécile Barrere-Tricca

Patent number: 7470359Abstract: The method enables the antihydrate compounds contained in a condensed-hydrocarbon liquid feedstock arriving through pipe 1 to be extracted. The liquid feedstock is brought into contact, in zone ZA, with a non-aqueous ionic liquid having the general formula Q+ A31 , where Q+ designates an ammonium, phosphonium, and/or sulfonium cation, and A31 designates an anion able to form a liquid salt. The antihydrate compounds in the liquid hydrocarbon feedstock evacuated through pipe 2 are eliminated. The ionic liquid charged with antihydrate compounds is evacuated through pipe 3, then introduced into evaporator DE to be heated in order to evaporate the antihydrate compounds. The regenerated ionic liquid is recycled through pipes 8 and 9 to zone ZA. The antihydrates are evacuated through pipe 7a.Type: GrantFiled: February 14, 2005Date of Patent: December 30, 2008Assignee: Institut Francais du PetroleInventors: Renaud Cadours, Fabrice Lecomte, Lionel Magna, Cécile Barrere-Tricca

Patent number: 7459134Abstract: The combustion fume flowing in through line 1 is decarbonated by contacting with a solvent in column C2. The solvent laden with carbon dioxide is regenerated in zone R. The purified fume discharged through line 9 comprises part of the solvent. The method allows to extract the solvent contained in the purified fume. The purified fume is contacted in zone ZA with a non-aqueous ionic liquid of general formula Q+ A?; Q+ designates an ammonium, phosphonium and/or sulfonium cation, and A? an anion likely to form a liquid salt. The solvent-depleted purified fume is discharged through line 17. The solvent-laden ionic liquid is regenerated by heating in evaporation device DE. The solvent separated from the ionic liquid in device DE is recycled.Type: GrantFiled: January 23, 2006Date of Patent: December 2, 2008Inventors: Renaud Cadours, Fabrice Lecomte, Lionel Magna, Cécile Barrere-Tricca

Publication number: 20070144970Abstract: This invention relates to a process for the preparation of a supported zeolite membrane that consists of a zeolite/substrate composite layer, whereby the crystallization stage is carried out while being stirred by a hydrothermal treatment of the immersed substrate. In addition, the process satisfies at least one of the following requirements: The crystallization is carried out with a water/silica molar ratio of 66-100, Before the crystallization stage, the porous substrate is pretreated by covering it at the outer periphery, where the zeolite is not desired, with a polytetrafluoroethylene film and by impregnating it with water in the pores where the zeolite is not desired, and the crystallization is conducted with a water/silica molar ratio of 10-100.Type: ApplicationFiled: December 20, 2006Publication date: June 28, 2007Inventors: Cecile Barrere Tricca, Anna Omegna, Loic Rouleau
