Abstract
The concentration of sulfuric acid exiting a countercurrent SO.sub.3 absorber is controlled by controlled addition of water vapor to the SO.sub.3 -containing process gas stream entering the absorber. The novel means of concentration control is useful for control of the acid concentration gradient in an SO.sub.3 absorption process and apparatus for high temperature absorption, so as to achieve high temperature absorption heat recovery while minimizing corrosion and formation of acid mist.
