摘要： Hydrogen sulphide is extracted from a supply gas as elemental sulphur using a reactor comprising a vertical cylinder (12) containing a downwardly moving bed of catalyst. Catalyst extracted at the bottom is elevated by a stream (26) of the supply gas in an unheated condition and is cooled by contact with the gas and subsequently by contact with suppiy air (11) to a temperature of the order of 150°F for injection into the top of the cylinder (12). A plurality of slip stream condensers (54-57) arranged seriatim along the length of the cylinder each act to extract 60% of the total gas flow upwardly in the cylinder and return the extracted gas downstream of the next adjacent extraction point so that the whole of the gas is extracted into one or more condensers for condensation of the sulphur formed on the catalyst. A water vapour condenser (100) is positioned downstream of the condensers to extract water vapour to further complete the reaction. The ratio of hydrogen sulphide to sulphur dioxide is maintained less than 2:1 and is corrected at a later stage of the process by injection of hydrogen sulphide.
