    摘要: 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.

    摘要: 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.

    摘要: 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.

    摘要: The method allows to remove mercaptans contained in a gaseous feed comprising hydrocarbons by carrying out the following stages: a) contacting, in a reactor R1, gaseous feed 1 with a liquid stream 13 comprising olefins, in the presence of a first acid catalyst so that the mercaptans react with the olefins so as to form sulfides, b) discharging an effluent 3 from reactor R1 and separating the effluent into a gas phase and a liquid phase so as to obtain a mercaptan-depleted treated gas 4 and a sulfide-laden liquid, c) separating the sulfide-laden liquid into a first fraction 6 and a second fraction 5, the volume flow rate of first fraction 6 being at least three times higher than the volume flow rate of second fraction 5, d) recycling first fraction 6 to stage a) as a first portion of said liquid stream to be fed into said reactor R1, e) regenerating second fraction 5 by cracking so as to obtain a sulfide-depleted second fraction 2 that is recycled to stage a) as a second portion of said liquid stream.

    摘要: An enhanced ether production process from an olefinic cut containing at least one iso-olefin and from an alcohol comprises a stage of removal of the acetonitrile present in the hydrocarbon feed by liquid-liquid extraction, the extraction solvent being a non-aqueous ionic liquid of general formula Q+A−, wherein Q+ is an ammonium, phosphonium and/or sulfonium cation, and A− an anion likely to form a liquid salt with said cation. Advantageously, the method according to the invention generally allows the amount of water at the etherification reactor inlet to be divided by at least two and thus the purity of the ether produced to be improved.

    摘要: The natural gas arriving through pipe 1 is deacidified by being brought into contact with a solvent in zone C. The solvent charged with acid compounds is regenerated in zone R. The acid gases, released into pipe 5 upon regeneration, include a quantity of solvent. The method enables the solvent contained in the acid gases to be extracted. In zone ZA, the acid gases are 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 is removed from the acid gases evacuated through pipe 6. The ionic liquid charged with solvent is regenerated by heating in an evaporator DE. The ionic liquid regenerated is recycled through pipes 8 and 9 to zone ZA. The solvent is evacuated through pipe 13.
