Abstract:
1. A method for disposal of alkyl di-sulphide compounds having the general formula of R—S—S—R, wherein R is an alkyl group, the method comprising the steps of: (a) combusting said alkyl di-sulphide compounds in the presence of an oxygen-containing gas in a sulphur dioxide generation zone using a di-sulphide burner, whereby at least part of the alkyl di-sulphide compounds is converted to sulphur dioxide to obtain a gas stream comprising sulphur dioxide and wherein the alkyl di-sulphide compounds are combusted at a temperature in the range of from 700° C. to 1800° C.; (b) reacting the gas stream comprising sulphur dioxide with hydrogen sulphide to obtain elemental sulphur in a Claus furnace, wherein the di-sulphide burner is coupled to the Claus furnace and oxygen-containing gas is fed to the di-sulphide burner.
