Abstract:
In a production mode a process for preparing sulfuric acid may involve oxidizing sulfur to sulfur dioxide in a first oxidation stage, and catalytically oxidizing the sulfur dioxide to sulfur trioxide in a second oxidation stage. The sulfur trioxide may be absorbed in at least one absorption stage. In the production mode, process gases from a last of the at least one absorption stage with respect to a flow direction are discharged. In a standby mode of the process, at least one heating stage for heating the process gases is connected. The process gases exiting from the at least one absorption stage are conveyed to the heating stage, and the process gases are circulated via the heating stage, the second oxidation stage, and the absorption stage.

Claim (Index 20):
The apparatus of  claim 19  wherein the closeable process gas discharge conduit and the closeable process gas feed conduit are connected via a closeable bypass conduit, with the closeable bypass conduit being open in the standby mode of the apparatus so that process gas from the first convertor stage is introducible via the closeable bypass conduit, bypassing the intermediate absorption apparatus, into the second convertor stage.
