Abstract
La presente se refiere a un proceso para la produccion de dioxido de cloro, comprendiendo dicho proceso, en forma continua, las etapas de: (a) alimentar a un reactor un ácido, clorato de metal alcalino y un agente reductor; (b) hacer reaccionar el clorato de metal alcalino con el ácido y el agente reductor para formar una corriente de producto que comprende dioxido de cloro y sal de metal alcalino del ácido; (c) llevar la corriente de producto desde el reactor hasta un eductor y mezclarla con fluido en movimiento alimentado al eductor y formar de este modo una corriente de producto diluido; (d) llevar la corriente de producto diluido a un separador gas-líquido en donde el gas es separado del líquido en el mismo; (e) retirar una corriente de producto gaseosa que comprende dioxido de cloro y gas inerte de dicho separador gas-líquido; y (f) retirar una fase líquida del separador gas-líquido. La presente también se refiere a una unidad de produccion para producir dioxido de cloro.This refers to a process for the production of chlorine dioxide, said process comprising, continuously, the steps of: (a) feeding a reactor an acid, alkali metal chlorate and a reducing agent; (b) reacting the alkali metal chlorate with the acid and the reducing agent to form a product stream comprising chlorine dioxide and alkali metal salt of the acid; (c) bringing the product stream from the reactor to an eductor and mixing it with moving fluid fed to the eductor and thereby forming a stream of diluted product; (d) bringing the stream of diluted product to a gas-liquid separator where the gas is separated from the liquid in it; (e) withdrawing a stream of gaseous product comprising chlorine dioxide and inert gas from said gas-liquid separator; and (f) withdrawing a liquid phase from the gas-liquid separator. This also refers to a production unit for producing chlorine dioxide.
