Abstract:
A process for preparing sulfuric acid may involve melting elemental sulfur in a melting stage to give molten sulfur. Sulfuric acid is subsequently produced from the molten sulfur. Further, sulfur-containing offgases formed in the melting stage may be subjected to oxidation in a supplementary oxidation stage in which sulfur-containing components of the offgases are oxidized to sulfur dioxide. The process may further involve processing the sulfur dioxide to give at least one reaction product. The melting stage may be operated without emissions by processing all of the offgases from the melting stage. An apparatus may be employed for carrying out such a process.”

Claim (Index 31):
The apparatus of  claim 30  wherein a second multistage converter of the multistage converter is connected to the intermediate absorption tower such that offgases and process gas from the intermediate absorption tower is introduced into the second converter stage.
