Abstract
This invention relates to the recovery of energy in the manufacture of sulfuric acid, and more particularly to enhanced recovery of energy from the absorption of wet SO3 in sulfuric acid. The invention is further directed to control of mist formation during SO3 absorption, and of the sulfuric acid mist content of the gas stream leaving the SO3 absorption step in a process wherein SO3 absorption energy is recovered from absorption acid in useful form.
