Abstract
SE DESDESCRIBE UN REACTOR DE COLUMNA DE BURBUJAS, QUE ESTA CARACTERIZADO A TRAVES DE UN GRADO DE ESBELTEZ CON UNA RELACION DE LA ALTURA A SU DIAMETRO DESDE 2 HASTA 50, CON UNA AFLUENCIA PARA LOS ELEMENTOS QUE SIRVEN COMO MEDIO DE REACCION, EL CARBONATO ETILENGLICOL (EGC) PRESENTE O EL CARBONATO PROPILENGLICOL (PGC), EN EL EXTREMO INFERIOR DE LA COLUMNA DE BURBUJAS Y/O UNO O MULTIPLES LUGARES DOSIFICADORES PARA LOS EDUCTOS CO2 Y OXIDO DE ETILENO (EOX) U OXIDO DE PROPILENO (POX) POR ENCIMA DE LA AFLUENCIA PARA EL MEDIO DE REACCION, CON UNA EVACUACION PARA LA MEZCLA DE REACCION EN EL EXTREMO SUPERIOR DE LA COLUMNA DE BURBUJAS. CON UN DISPOSITIVO DE DISTRIBUCION A CONTINUACION PARA LA MEZCLA DE REACCION DESARROLLADA PARA LA DISTRIBUCION DE LA MEZCLA DE REACCION A SER EXTRAIDA Y A SER PREPARADA POR UNA PARTE Y LA MEZCLA DE REACCION CICLIDIZADA POR OTRA PARTE, Y ADEMAS CON UNA CONDUCCION DE GUIA DE RETORNO PARA LA ADICION DE LA MEZCLA DE REACCION RECICLIDIZADA. ESTE REACTOR DE COLUMNA DE BURBUJAPUEDE SER UTILIZADO EN FORMA VENTAJOSA EN UN PROCESO PARA LA ELABORACION CONTINUA DE EGC O PGC, DE FORMA QUE SE REALIZA EN UNA ZONA DE TEMPERATURAS DESDE 100 HASTA 200 UNA ZONA DE PRESION DESDE 5 HASTA 200 BAR Y EN UNA RELACION MOLAR DESDE 1,01 HASTA 1,5 MOLES DE CO2 POR MOL DE OXIDO ALQUILENO EN PRESENCIA DE EGC O PGC COMO MEDIOS DE REACCION EN UNA CANTIDAD QUE ALCANZA DESDE 7 HASTA 350 VECES LA CANTIDAD EGC O PGC NUEVA FORMADA.
