Title
(EN) SULFUR DIOXIDE REMOVAL FROM WASTE GAS
(FR) ÉLIMINATION DE DIOXYDE DE SOUFRE PRÉSENT DANS DES GAZ RÉSIDUAIRES
Abstract
(EN)
The present invention concerns a process wherein a gas, containing SO2 and O2 is brought in contact with a mixture of from 95% vol. to 50% vol. of activated carbon catalyst and from 5% vol. to 50% vol. of an inert filler material; wherein the SO2 is converted to H2SO4 on the activated carbon catalyst and is then washed from the activated carbon catalyst to obtain a H2SO4 solution.
(FR)
La présente invention concerne un procédé dans lequel un gaz contenant SO2 et O2 est amené en contact avec un mélange de 95 % en volume à 50 % en volume de catalyseur au charbon actif et de 5 % en volume à 50 % en volume d'un matériau de charge inerte, le SO2 étant converti en H2SO4 sur le catalyseur au charbon actif et étant ensuite éliminé du catalyseur au charbon actif par lavage afin d'obtenir une solution de H2SO4.
