摘要： In a process and apparatus for treating a gas containing hydrogen sulphide and sulphur dioxide, the gas is contacted with an organic solvent (1)for example, a polyalkylene glycol, containing a catalyst for example, an alkaline salt of a week organic acid, in at least one gas-liquid reactor contactor (2) and a gas (20) substantially no longer containing hydrogen sulphide and sulphur dioxide is recovered. The effluent contains sulphur vapor. It is cooled by mixing with a solvent-water mixture (14) or by cooled solvent in a cooling zone (7) to produce a suspension of sulphur crystals in the solvent. The crystallised sulphur is separated from the solvent in a separation zone (30) and the cooled solvent is recycled (13). An effluent (17) which is free of sulphur gas is obtained.

摘要： A process for pretreating a very acid natural gas containing a substantial amount of hydrogen sulfide (H2S), possibly combined with carbon dioxide (CO2), includes at least a stage wherein the initial natural gas is contacted in a distillation column with a liquid condensate itself resulting from cooling of the gaseous fraction obtained during the contacting stage. This solution allows to eventually recover at a lower cost a gas enriched in methane, depleted in hydrogen sulfide and freed from substantially all of the water it contains, and a liquid phase containing most of the hydrogen sulfide, substantially all of the water and depleted in hydrocarbon. Control of the thermodynamic conditions during the stages that characterize the process, according to the water content of the gas during treatment, allows progressive exhaustion of the water contained in the gas while preventing hydrates formation.

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 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.
