The present invention relates to a process and a device for the combustion of sulphur and/or sulphur-containing compounds, via which a sufficient production of SO-containing gases having a high SOconcentration is made possible. The combustion preferably proceeds using a combustion gas which has an oxygen fraction at least as high as air, but preferably a higher fraction of oxygen. The process and the device should be suitable, in particular, for providing sulphur dioxide as a source for further production of sulphuric acid or highly concentrated SO-containing gases. In addition, the device and the process should be suitable for oxidizing hydrogen-sulphide-containing gases, such as occur, for example, in the refinery industry, in high concentrations to SO.

Device and method for the combustion of sulfur and sulfur-containing compounds

Regenerator and process for regenerative thermal oxidation of offgases comprising halooganosilocon compounds in which offgases are heated in the regenerator, fed to an oxidation zone present in the regenerator to oxidize the haloorganosilicon compounds to SiOand hydrogen halides which form a flue gas which is then cooled in the generator to a temperature below its acid dew point and is discharged.
