Abstract

A method for the manufacture of sulfuric acid by a process of the aforementioned class, characterized in that two gas springs containing sulfur dioxide are used, respectively at high temperature and at low temperature, the spring being fed at low temperature in the tower of Interabsorption through a catalytic system and the residue thereof, leaving the interabsorption tower, is mixed with the spring at high temperature to be fed to the final absorption tower through another additional catalytic system, there being no device of heat exchange between the inter-absorption tower and the additional catalytic system.
