Abstract

L'invention concerne un procédé et un appareil de production d'acide sulfurique concentré au moyen d'un absorbeur. Pour l'absorption de grandes quantités de SO3 (ou H2O) dans de l'acide sulfurique à concentration différente, un tube vide est intégré à l'intérieur dudit absorbeur garni, le gaz et l'acide étant introduits dans la partie supérieure du tube vide et passant de manière cocourante dans la partie inférieure dudit absorbeur garni suivant. Le gaz remonte ensuite à travers la garniture, de l'acide supplémentaire est introduit à l'intérieur de l'absorbeur garni au-dessus de la garniture et est mélangé à contre-courant avec le gaz dans la région de la garniture, le gaz provenant de la partie supérieure de l'absorbeur fixe étant retiré et l'acide étant évacué du fond de l'absorbeur garni.
