Abstract (en)
[origin: EP3984621A1] A method (100) for the desulphurisation of a sour gas mixture is provided, wherein the sour gas mixture is subjected to a free-flame oxidation producing a process gas containing sulphur dioxide, and wherein the process gas is at least in part subjected to a catalytic conversion converting the sulphur dioxide at least in part to elementary sulphur, the sour gas mixture being subjected to the free-flame oxidation in a first amount per time unit in a first mode of operation and in a second amount per time unit not exceeding a third of the first amount per time unit in a second mode of operation, and the free-flame oxidation being performed using an oxydant stream with an oxygen content exceeding that of atmospheric air in the first mode of operation. The free-flame oxidation is performed using the oxydant stream with the oxygen content exceeding that of atmospheric air in the second mode of operation, and heat is supplied by combusting a fuel stream other than the sour gas mixture in the second mode of operation. A corresponding apparatus is also part of the invention.
