Title
(EN) DESULFURIZATION OF INCONDENSIBLE GASES FROM THE VACUUM DISTILLATION OF CRUDE OIL
(FR) DESULFURATION DE GAZ NON CONDENSABLE PROVENANT DE LA DISTILLATION SOUS VIDE DE PETROLE BRUT
Abstract
(EN)
Process and apparatus for desulfurizing the gaseous product of the vacuum distillation of the heavy fraction of crude oil. The initial gaseous mixture (8) to be desulfurized is an incondensible gas that contains hydrogen sulfide. A gas-liquid contact column (2) contains first and second sections (3, 4) that contain beds of packing material, which may be structured or random packing. The beds are supported below irrigation devices (18) that promote the wetting of the beds but cause minimal pressure loss in the gases passing through the column. The initial gaseous mixture is dried and introduced (14) into the first section (3) of the column. Also introduced into the first section of the column is a fresh ammonia solution (9) containing the stoichiometric quantity for reacting with the amount of hydrogen sulfide present in the initial gaseous mixture. Finally, the first section of the column receives a second ammonia solution that is passed from the second section of the column into the first section.
(FR)
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.
