Abstract
A method of manufacturing sulfuric acid according to the contact method, in which a gas with SO2 that normally contains at least 10 volume percent SO2, and obtained by combustion of sulfurous materials, with air, in an oven, usually sulfur in a sulfur furnace or sulfur pyrite or other sulfide in a roasting furnace, it is introduced into a contact apparatus (furnace) where a gas containing SO3 is produced, by catalytic oxidation of SO2 to SO3, usually 98 volume percent, approximately, after which SO3-containing gas is introduced into an absorption tower where SO3 and some SO2 are absorbed in concentrated sulfuric acid, typically approximately 98%, and the waste gas leaves the system from the absorption tower, characterized in that all the sulfuric acid that comes from the absorption tower, substantially without cooling, possibly with the addition of water necessary for the The process, or preheated, is introduced into a ventilation tower and there it passes in the opposite direction to the main part, at least, of the air destined to the combustion of the sulfur material and to the adjustment of the SO2 content for the contact procedure, whose Air takes in the SO2 absorbed from the sulfuric acid and is then supplied to the combustion furnace.
