Sulfur Trioxide and Oleum - Veolia North America

sulfuric acid. As you can see, sulfur and air are brought in and burned to make sulfur dioxide (SO 2). The SO 2 goes through a series of gas cooling and heat recovery operations, and then is run through a catalytic converter to make sulfur trioxide (SO 3). The sulfur trioxide is absorbed in sulfuric acid. Water is added to control the sulfuric
