摘要： The present invention aims to isolate the azeotropes formed in a distillation column (B1) by methanol, propane and butane. The azeotropes are then liquefied in heat exchanger (E2) and mixed in contactor (M1) with water in order to dissolve the methanol in water. The mixture is then fed into a decantation tank (D2) to separate the aqueous phase from the liquid hydrocarbon phase. Finally, an aqueous phase containing methanol is discharged and the methanol-depleted hydrocarbon phase is recycled to distillation column (B1) as reflux.
摘要翻译：本发明的目的是通过甲醇，丙烷和丁烷来分离在蒸馏塔（B1）中形成的共沸物。然后将共沸物在热交换器（E2）中液化，并在接触器（M1）中与水混合，以便将甲醇溶解在水中。然后将混合物进料到倾析罐（D2）中以将水相与液态烃相分离。最后，排出含有甲醇的水相，将甲醇耗尽的烃相作为回流再循环至蒸馏塔（B1）。

摘要： The raw natural gas is deacidized and dehydrated in units DA and DH. The treated gas is then purified by adsorption of the mercaptans in first enclosure A1. Part of the purified gas is heated in E1, then fed into second enclosure A2 so as to discharge the water adsorbed by the adsorbent material contained in this second enclosure. A water-laden purge gas is fed into third enclosure A3 containing a mercaptan-laden adsorbent material. In A3, the mercaptans are desorbed and replaced by the water. The gas from the third enclosure is washed in unit L, then recycled.

摘要： The mercaptan-laden natural gas is contacted with a mercaptan-adsorbing sieve T1. The mercaptan-rich gaseous effluent obtained upon regeneration of sieve T2 is then contacted with an olefin-containing liquid feed in the presence of an acid catalyst. Under suitable conditions, the mercaptans are absorbed in the liquid feed and they react with the olefins so as to form solvent-soluble sulfides. A solvent regeneration stage allows the capture agent to be recycled.

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.

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 natural gas is deacidized by contacting in zone 3 with a solvent containing amine in aqueous solution. The gas is then dehydrated by contacting in zone 4 with a solvent very rich in amine. After the contacting operations, the solvent containing H2S. and water is expanded in drum 9, then regenerated in column 11. Part of the regenerated solvent is sent to zone 3. Another part of the regenerated solvent is vacuum distilled in column 18 so as to produce an amine-rich solvent that is sent to zone 4.
