Abstract

Procedimiento para el tratamiento del gas residual resultante en la preparación de cloruro de cianurilo, caracterizado porque este gas residual es introducido con una presión de 1-5 bares (absolutos), preferentemente de 1-4 bares (absolutos), en la parte inferior de una columna, se hacen reaccionar en la columna con la cantidad de cianuro de hidrógeno por lo menos equivalente para la formación de cloruro de cianógeno y se conduce en contracorriente con respecto al agua alimentada en la parte superior de la columna, después de lo cual la solución acuosa de cloruro de cianógeno formada en tal caso se retira de la parte inferior de la columna y se devuelve preferentemente a la parte de preparación para la obtención de cloruro de cianógeno, mientras que el gas de escape purificado sale de la columna en su parte superior.
