Sulfur removal methods
Abstract:
A method for removing sulphur from a fluid by the steps of providing a first fluid comprising a sulphur-containing compound; adsorbing the sulphur of sulphur-containing compound onto an adsorbent; regenerating the adsorbent by oxidation of the adsorbed sulphur to sulphur dioxide thereby yielding an off-gas stream comprising sulphur dioxide; providing a second fluid comprising hydrogen sulphide, using the second fluid and the off-gas stream as reactants in a Claus process for producing elemental sulphur, wherein a part of hydrogen sulphide provided by the second fluid is oxidized to sulphur dioxide and water at reaction temperature, the residual hydrogen sulphide, the resulting sulphur oxide and the sulphur oxide provided by the off-gas stream are converted to elemental sulphur, the oxygen required for the oxidation of the hydrogen sulphide provided by the second fluid is provided by an air stream, and the off-gas stream dilutes the second fluid in the Claus process.
