ABSTRACT:
A noncatalytic process for producing sulfur trioxide and sulfuric acid in which sulfur is combusted with an oxygen-rich gas in the presence of recycled sulfur dioxide-rich gas to form sulfur trioxide which is absorbed in sulfuric acid and yield a sulfur dioxide rich gas which is compressed to form the recycled sulfur dioxide rich gas.
