Abstract

La presente invención se refiere a un proceso para la remoción de azufre a partir de un gas que contiene compuestos de azufre como H2S, SO2, COS, CS2..., en una cantidad de hasta 15% en peso; en particular se refiere a gases que se emanan del proceso Claus. El proceso comprende una primera hidrogenación de componentes de azufre en H2S, el gas de hidrogenación es usado para regenerar un lecho desactivado de catalizador de oxidación, ambos se llevan a cabo a 200-500 °C. Después de la remoción de azufre, el gas resultante se somete a una segunda etapa de hidrogenación y después a una etapa de oxidación directa, tal etapa es operada por debajo del punto de rocío del azufre para atrapar el azufre formado en el catalizador. En el ciclo adicional, las corrientes de gas son intercambiadas para así regenerar el catalizador en la corrida el cual es desactivado. En una modalidad preferida, el proceso opera en al menos 2 reactores idénticos, cada uno contiene un lecho de catalizador de hidrogenación al que le sigue (en el sentido del flujo de gas) un lecho catalizador de oxidación directa que contiene un intercambiador de calor integrado.
