Abstract

La invención consiste en un proceso para producir continuamente dióxido de cloro, comprende los siguientes pasos: diluir ácido sulfúrico de una concentración inicial que excede 90% en peso con agua; llevar el ácido sulfúrico diluido a una temperatura por debajo de los 100C; alimentar a un reactor el ácido sulfúrico diluido con una temperatura por debajo de los 100C a través de una primera boquilla de alimentación; alimentar al reactor mencionado (5) con una solución acuosa que comprende clorato de metal alcalino y peróxido de hidrógeno a través de una segunda boquilla de alimentación, donde las mencionadas primera y segunda boquilla de alimentación (1,2) son opuestas y dirigidas de manera enfrentada; reaccionando el clorato de metal alcalino con el ácido mineral y el peróxido de hidrógeno para formar una corriente de producto que contiene dióxido de cloro; y, extrayendo la corriente de producto del reactor. La invención se relaciona también con un aparato para producir dióxido de cloro.
