Abstract

When mixing two gases of different temperature and/or composition in a converter for producing SO3 from an SO2-containing gas, a first SO2-containing gas flow is introduced into the converter through a central supply pipe and passed through an integrated heat exchanger arranged around the central supply pipe, which is traversed by the first gas flow from the bottom to the top. A second gas flow is supplied via a ring conduit arranged above the integrated heat exchanger, from which the second gas flow is discharged through a plurality of openings and is fed into the first gas flow, so that it mixes with the same. Then, the gas mixture obtained is supplied to a contact stage of the converter, in which the SO2 is at least partly converted to SO3 on a catalyst.
