摘要： Process for pretreating a natural gas under pressure containing hydrocarbons, acid compounds such as hydrogen sulfide and carbon dioxide, and water. The natural gas is cooled to condense part of the water. The partially dehydrated natural gas is then contacted with a liquid stream consisting of a majority of hydrogen in two successive contact zones so as to obtain a natural gas containing substantially no water any more. Finally, this dehydrated natural gas is cooled to condense and separate the acid compounds, this cooling stage being carried out by means of a heat exchanger, an expander or a venturi neck.

摘要： A process is provided for removing hydrogen sulfide out of a gas, such as natural gas. The hydrogen sulfide contaminated gas is contacted with a catalytic aqueous solution containing a polyvalent metal chelating agent under conditions in which the hydrogen sulfide is oxidized into elemental sulfur and the polyvalent metal chelating agent is reduced to a lower oxidation state, and the treated gas is recovered. The solution containing the polyvalent metal chelating agent and the elemental sulfur is filtered at a pressure of at least 1 Mpascals. At least a portion of the filtered solution containing the polyvalent metal chelating agent is degassed and/or depressurized for the removal of components such as light hydrocarbons and carbon dioxide; contacted with an oxidizing agent and recycled back to the hydrogen sulfide removal step. By filtering the sulfur out of the solution at a pressure of at least 1 Mpascal, foam formation and clogging problems can be avoided.

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.

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.
