Abstract
In order to provide a method for the purification of a raw gas stream containing water vapour that is simple and cost-efficient to perform, it is proposed that the method should comprise the following: feeding the raw gas stream to a reforming region in which contaminants in the raw gas stream react chemically with the water vapour in the raw gas stream, as a result of which a reformed raw gas stream is obtained; feeding the reformed raw gas stream and an oxidising agent stream to an oxidation region in which constituent parts of the reformed raw gas stream react chemically with oxidising agent of the oxidising agent stream, as a result of which a clean gas stream is obtained. Moreover, optionally a closed-loop control of the oxygen content is provided. Further, it is optionally provided for the clean gas stream to be fed to a condenser, as a result of which the volumetric flow of the clean gas stream is reduced and/or as a result of which energy can be recovered and used for pre-heating the oxidising agent and for other production processes.
