Abstract

EL CRISTALIZADOR (1) ABARCA UN RECIPIENTE (2), QUE INCLUYE UN TUBO (4) DE NERVIOS EN FORMA DE U SEGUN UNA DISPOSICION DE TIPO DE HAZ. CADA TUBO (4) DE NERVIOS ESTA SUJETO EN UNA PARED (8) FRONTAL DEL RECIPIENTE (2) Y SE APOYA DE FORMA MOVIL RELATIVA EN LA OTRA PARED (25) FRONTAL. LOS ARCOS (18) TUBULARES DEL TUBO (4) DE NERVIO DESCANSAN EN UNA CAMARA (26) DE DILATACION. LOS EXTREMOS (22) DE PATILLA LIBRES DEL TUBO (4) DE NERVIOS DESEMBOCAN EN LOS ESPACIOS (29-35) DE SOBRECONDUCCION DE UNA CAMARA (36) DISTRIBUIDORA, QUE SE SUELDA SOBRE LA PARED (8) FRONTAL. LOS TUBOS (4) DE NERVIOS SE ALIMENTAN A PARTIR DE UN GAS (RG) DE REACCION Y SE DISPONEN EN EL LADO INTERNO CON UN MEDIO (KO) REFRIGERANTE. CON ELLO PRECIPITA EL ANHIDRIDO DE ACIDO FTALICO A PARTIR DEL GAS (RG) DE REACCION SOBRE LOS TUBOS (4) DE NERVIOS. MEDIANTE LA ALIMENTACION DE LOS TUBOS (4) DE NERVIOS CON ACEITE DE CALENTAMIENTO (HO) SE FUNDE EL ANHIDRIDO DE ACIDO FTALICO A PARTIR DE LOS TUBOS (4) DE NERVIOS. EN LA PROXIMIDAD DE LAS PAREDES LATERALES DEL RECIPIENTE (2) PUEDE DISPONERSE UNA CONFIGURACION EN FORMA DE U QUE SE EXTIENDE LONGITUDINALMENTE DESDE LOS TUBOS NO NERVADOS EN LA ZONA NO OCUPADA POR LOS TUBOS (49 DE NERVIOS. TODOS LOS TUBOS (4) DE NERVIOS Y LOS TUBOS NO NERVADOS SE INTERCEPTAN DE FORMA TRANSVERSAL CON RESPECTO A LOS TUBOS (40) SOPORTE.
