Abstract
Stack gases derived from combustion of hydrocarbons are scrubbed by direct contact with an inert liquid capable of taking sulphur compounds into solution. The inert liquid pregnant with sulphur compounds is injected into a reactor where the sulphur compounds are converted into sulphurous acid or in the presence of a catalyst wet oxidized into sulphuric acid. Product acid is withdrawn from the reactor and the stripped inert liquid is returned to the scrubber to repeat the process. Waste heat is captured for further useful work.
