Title (EN) A METHOD OF MANUFACTURING SULPHURIC ACID
(FR) PROCEDE DE PRODUCTION D"ACIDE SULFURIQUE
Abstract: front page image
(EN)A method for manufacturing sulphuric acid from sulphur-dioxide containing gas, particularly furnace gas obtained from metallurgical processes by oxidation to sulphur trioxide in the presence of a catalyst and conversion of the sulphur trioxide to sulphuric acid. The sulphur dioxide is first separated from the gas preferably converted to liquid form and is then subsequent to being vaporized in a stoichiometric excess oxidized with oxygen.
(FR)Procede de production d"acide sulfurique a partir d"un gaz contenant de l"anhydride sulfureux, en particulier du gaz de four obtenu a partir de procedes metallurgiques par oxydation en anhydride sulfurique en presence d"un catalyseur et par conversion de l"anhydride sulfurique en acide sulfurique. L"anhydride sulfureux est d"abord separe du gaz de preference converti en liquide puis, apres avoir ete vaporise en exces par rapport aux proportions stoechiometriques, il est oxyde avec de l"oxygene.
