Abstract

PROCEDIMIENTO PARA LA OBTENCION DE ETANOL. CONSISTE EN EFECTUAR UNA HIDRATACION CATALITICA DE ETILENO. SE OBTIENE ETANOL ACUOSO BRUTO, EN QUE UNA SECCION DE PURIFICACION SE HACE PASAR A LA PRIMERA COLUMNA DE DESTILACION, SE DESCARGA UNA FRACCION DE CABEZA QUE CONTIENE LA MAYOR PARTE DE IMPUREZAS Y EL PRODUCTO DE COLA SE PASA A UNA SEGUNDA COLUMNA. SE RECUPERA EL AZEOTROPO ETANOLAGUA, SE HACE PASAR UNA O MAS CORRIENTES LATERALES QUE CONTIENEN IMPUREZAS DE PUNTOS DE EBULLICION SUPERIOR DESDE UNA PARTE INFERIOR DE LA SEGUNDA COLUMNA A UNA TERCERA COLUMNA, SE SEPARA UNA FRACCION DE CABEZA QUE CONTIENE IMPUREZAS.
