    • The present invention relates to a method of removing hydrogen sulphide from a gas stream wherein the hydrogen sulphide is scrubbed from the gas phase by means of an aqueous solution, the hydrogen sulphide in the aqueous solution is biologically oxidized in a bioreactor to produce elemental sulphur, and the elemental sulphur is separated from the aqueous solution, characterized in that the gas stream to be treated is cooled to such a degree that at least sufficient water vapour condenses from said gas stream to compensate for the discharge stream for the purpose of removing salts. This means that no water need be supplied to the bioreactor. This method is suitable, in particular, for gas streams which contain hydrogen sulphide, the hydrogen sulphide having been obtained by catalytic conversion of sulphur compounds.

    • A process for converting hydrogen sulfide which is contained in a gaseous feed stream to elemental sulfur and hydrogen. The process comprises contacting said gaseous feed stream with a polar organic solvent having an anthraquinone, and optionally a complexing agent, dissolved therein, reacting the hydrogen sulfide gas and anthraquinone to produce sulfur and an anthrahydroquinone in the solvent, and catalytically dehydrogenating the anthrahydroquinone to anthraquinone and hydrogen. In accordance with the present invention, a relatively small quantity of water is added to a polar organic solvent thereby increasing the elemental sulfur which is precipitated and thus recovered. The addition of water prior to or during sulfur production also increases hydrogen product selectivity in the subsequent dehydrogenation of anthrahydroquinone.

    • Hydrogen sulphide can be removed from a gaseous stream by contact with a 2,3-dialkyl substituted naphthoquinone in the presence of a catalytic amount of an amine catalyst dissolved in a hydrophobic organic solvent system, with consequential formation of a corresponding quinhydrone and insoluble elemental sulphur. Preferably the total number of carbons in the alkyl substituents is from 2 to 6. Particularly suitable compounds comprise dimethyl and/or ethyl/methyl naphthoquinones. Preferably the amine catalyst has a pK in the range of about 9 to 11.5. Preferred solvent systems comprise mixtures of aromatic hydrocarbons with aliphatic esters such as methyl cyclohexanol acetate or dialkylketones such as diisobutylcarbinol. Advantageously, the naphthoquinones react with hydrogen sulphide significantly faster than do the anthraquinone or tetrahydroanthraquinone compounds hitherto proposed. The insoluble sulphur can be recovered as product and the resultant solution containing a reduced species, believed to be naphthoquinhydrone, can be contacted with an oxygen-containing gas for generation of hydrogen peroxide and reformation of the naphthoquinone. After extraction of the hydrogen peroxide with water, the organic solution is available for contact with further hydrogen sulphide.
