Sulfuric acid production

Sulfuric acid is an important bulk chemical which is used primarily in the production of fertilizer. With SO2 and SO3 as intermediate products, highly corrosive components are part of the production process. These oxides and their acids exhibit increased dew points, which is a particular challenge for analysis after extraction from the process. When it comes to both process control and emission monitoring, modern hot/wet extractive processes are superior to conventional cold/dry extractive processes. Typical applications are the analysis of SO2 and O2 at the inlet of the contact ovens as well as SO2, SO3 or H2SO4 at the stack.
