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 19):
The apparatus of  claim 17  wherein the second oxidation facility is configured as a multistage converter, wherein each converter stage of the multistage converter comprises a catalyst tray, wherein a first converter stage of the multistage converter is connected via a process gas discharge conduit to an intermediate absorption apparatus, wherein the intermediate absorption apparatus is connected via at least one process gas feed conduit to a second convertor stage of the multistage converter so that process gases from the first convertor stage are introducible via the intermediate absorption apparatus into the second convertor stage in the production mode.
