Abstract
A process is described for the conversion of sulfur dioxide into sulfur trioxide, and derivatives of sulfur trioxide, such as sulfuric acid. The process is particularly efficient for removing sulfur dioxide from stack gas, such as exhaust and waste gas associated with industrial processes, such as chemical processes, combustion of coal and oil, and processes for treating liquid and solid wastes.
