Abstract
Procédé et appareil de désulfuration du produit gazeux provenant de la distillation sous vide de la fraction lourde de pétrole brut. Le mélange gazeux de départ (8) à désulfurer est un gaz non condensable contenant de l'acide sulfhydrique. Une colonne de contact gaz/liquide (2) présente une première et une seconde parties (3, 4) contenant des lits de matière de garniture structurée ou aléatoire et disposés sous des dispositifs d'irrigation (18) qui en assurent l'humidification tout en n'occasionnant que des pertes minimes de pression dans le gaz traversant la colonne. Le mélange gazeux de départ (8) est séché puis introduit (14) dans la première partie (3) de la colonne avec une solution neuve de gaz ammoniac (9) en quantité
stoechiométrique pour assurer la réaction avec la quantité d'acide sulfhydrique présente dans le mélange gazeux de départ. La première partie de la colonne reçoit enfin une deuxième solution de gaz ammoniac qu'on fait passer de la deuxième partie de la colonne dans la première partie.
