Abstract

Un procedimiento para la eliminación por oxidación directa catalítica de sulfuro de hidrógeno de una corriente gaseosa (1) que contiene sulfuro de hidrógeno, consistiendo dicho procedimiento en a) mezclar una corriente gaseosa (1) que contiene sulfuro de hidrógeno con un gas que contiene oxígeno (2) para obtener una corriente gaseosa que contiene tanto sulfuro de hidrógeno como oxígeno; b) transferir la corriente gaseosa que contiene tanto sulfuro de hidrógeno como oxígeno a una primera sección (8) de un primer reactor (20), donde dicha primera sección (8) contiene un lecho adiabático no enfriado que contiene un primer catalizador que cataliza la oxidación del sulfuro de hidrógeno con oxígeno y la oxidación del sulfuro de hidrógeno con dióxido de azufre, donde la temperatura del lecho adiabático es T1; c) transferir la corriente gaseosa de la primera sección (8) del primer reactor (20) a una segunda sección (9) del primer reactor (20), donde dicha segunda sección (9) contiene un segundo catalizador que es diferente del primer catalizador y donde dicha segunda sección (9) es mantenida a una temperatura T2, donde T2 £ T1 y T2 es superior a la temperatura del punto de rocío del azufre elemental y no mayor de 300 °C, mediante lo cual se obtiene una corriente gaseosa empobrecida en sulfuro de hidrógeno; d) transferir la corriente gaseosa empobrecida en sulfuro de hidrógeno a un condensador de azufre (30) para obtener una corriente gaseosa empobrecida en azufre; e) transferir la corriente gaseosa empobrecida en azufre a la primera sección (22) de un segundo reactor (21), donde dicha primera sección (22) contiene el mismo catalizador que la primera sección (8) del primer reactor (20), donde la primera sección (22) del segundo reactor (21) es mantenida a una temperatura que está por encima del punto de rocío del azufre elemental, de tal forma que, en la primera sección (22) del segundo reactor (21) no precipita ningún azufre elemental como líquido o sólido sobre el catalizador; f) transferir la corriente gaseosa de la primera sección (22) del segundo reactor (21) a la segunda sección (23) del segundo reactor (21), que contiene el mismo catalizador que la segunda sección (9) del primer reactor (20), y donde dicha segunda sección (23) es mantenida a una temperatura que es igual o inferior al punto de rocío del azufre elemental, de tal forma que, en la segunda sección (23) del segundo reactor (21), precipita azufre elemental como líquido o sólido sobre el catalizador; g) retirar la corriente gaseosa desazufrada del segundo reactor (21), y h) después de un tiempo definido, cambiar las condiciones de operación del primer reactor (20) y del segundo reactor (21) y cambiar el flujo de gas simultáneamente, de tal forma que el anterior segundo reactor (21) se convierte en el nuevo primer reactor y el anterior primer reactor (20) se convierte en el nuevo segundo reactor, i) donde la corriente gaseosa que contiene sulfuro de hidrógeno (1) que se introduce en el primer reactor no ha sido previamente sometida a la etapa de combustión de un procedimiento Claus.
