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： 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.

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 steam-rich stream is fed into third enclosure A3 containing a mercaptan-laden adsorbent material. In A3, the mercaptans are desorbed and replaced by the steam.

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： In a process for dehydration/fractionation of a wet natural gas containing heavy constituents and light constituents, In the presence of methanol, aqueous liquid phases are combined and the resultant combined aqueous liquid phase contacted with the first part of the gas to be scrubbed, which carries along the major part of the methanol, which allows to collect practically pure water. Before this step, all or part of one or both of the aqueous liquid phases and/or all or part of the aqueous liquid phase from a washing zone is sent to a distillation stage where practically pure methanol is collected at the top and a methanol-depleted aqueous liquid phase is collected at the bottom prior to being sent back to the first stage or used for the washing stage.

摘要： In order to make an optical connector (1, 4), particularly the female part (4) thereof, easier to clean, it is provided that, upon disconnection, ferrules (5) embedded in the female cavities (9) of the complementary connector are drawn flush (7) with the complementary connector by sliding the sleeve (6) which forms it. It is shown how, by this arrangement, optical connectors may be cleaned more frequently and easily. The connector is improved by providing a clip (37) which accommodates a pusher at the end of its pushing stroke.

摘要： The gas to be processed, flowing in through line 10, contains impurities. This gas is contacted in column C1 with a solvent flowing in through line 18. The scrubbed gas is discharged through line 19. The impurity-laden solvent recovered through line 12 is regenerated by expansion, then by distillation in column C2. The invention proposes carrying out expansion by means of two-phase turbines T1 and T2.
