Abstract

PROCEDIMIENTO DE SEPARACION DE CLORURO DE VINILO NO REACCIONADO DESDE UNA DISPERSION DE POLIMERIZADO ACUOSA. LA SEPARACION SE REALIZA EN UN DESGASIFICADOR DONDE SE LLEVA LA DISPERSION A UNA TEMPERATURA POR DEBAJO DE 120 C., A LA VEZ UE SE LA SOMETE A UN ARASTE POR FLUIDO INERTE, VAPOR DE AGUA, PROVOCANDO A CONTINUACION UNA BAJADA DE PRESION PARA MANTENER LA EBULLICION SIN APORTACION DE VAPOR DE AGUA. SE PRODUCE ASI UNA SALIDA DE VAPOR DE AGUA QUE ARRASTRA CLORURA DE VINILO, QUE LLEGA AL CONDENSADOR, DONDE SE SEPARA EL CLORURO DE VINILO QUE SE EXTRAE POR LA SALIDA .
