摘要： A method of removing hydrogen sulphide from a gas stream wherein the hydrogen sulphide is scrubbed from the gas phase by 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 the 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.

摘要： The invention is directed to a process to prepare a gas mixture of hydrogen and carbon monoxide from an ash containing carbonaceous feedstock. The process involves a partial oxidation obtaining liquid ash and a gas mixture comprising hydrogen, carbon monoxide and solids. The liquid ash is separated from the gas mixture and the temperature of the gas mixture is reduced in the absence of the separated ash. The gas mixture is passed through a vertically positioned diptube wherein water is added to the gas mixture flowing through the diptube to obtain a gas/water mixture. The liquid is separated from the gas/water mixture. The gas thus obtained is passed together with an amount of liquid water through a venturi mixer and scrubbed.
