Abstract

APARATO PARA LA SEPARACION DE AGUA DE MEZCLAS CON ACETATO DE VINILO Y ACIDO ACETICO. EL RECIPIENTE (2) POSEE CONDENSADO CON AGUA ABUNDANTE. EL RECIPIENTE (6) POSEE FRACCION DE SALIDA CON COLAS CON POCA AGUA. AMBOS APORTAN SUS CONTENIDOS A UNA COLUMNA (1) DE 60 PLATOS CON CALENTAMIENTO ELECTRICO DE COLAS. EL RECIPIENTE (2) LO APORTA AL PLATO 45 G Y EL RECIPIENTE (6) PUEDE HACERLO AL 45 G O AL 30 G. LOS VAPORES QUE SALEN POR LA PARTE SUPERIOR VAN A PARAR AL COLECTOR (16), A TRAVES DE UN REFRIGERADOR (14), DONDE SE SEPARAN EN DOS FASES. LA FASE DE ACETATO DE VINILO (19) SE DEVUELVE A LA PARTE SUPERIOR DE LA COLUMNA. LA FASE DE AGUA (17) SE RETIRA. EL RECIPIENTE (25) BOMBEA UNA SOLUCION DE ESTABILIZADOR. EL NIVEL DE LIQUIDO EN LAS COLAS (29) SE MANTIENE CONSTANTE RETIRANDO MEZCLA ANHIDRA DE ACETATO DE VINILO-ACIDO ACETICO A TRAVES DE LA CONDUCCION (30). L
