Abstract

UN NUEVO REACTOR QUIMICO; UNO PARTICULARMENTE UTIL PARA LA PRODUCCION DE POLIMEROS, ESPECIALMENTE ELASTOMEROS TALES COMO CAUCHO BUTILICO. EL REACTOR (10) CONTIENE: (1), UN SISTEMA DE PASO DE DOS TUBOS, FORMADO POR UN HAZ (20) DE TUBOS CENTRALES O INTERNOS, A CUYO TRAVES PASA EN UNA DIRECCION UNA MEZCLA O LODO DE MONOMEROS POLIMERIZABLES Y CATALIZADOR, RECICLANDOSE VIA UN HAZ (30) DE TUBOS EXTERNOS, EN LA DIRECCION OPUESTA, EN DISTRIBUCION (2) DE FLUJO ESENCIALMENTE UNIFORME, MIENTRAS LOS TUBOS DE LOS HACES TUBULARES EXTERNOS Y CENTRALES SE MANTIENEN DENTRO DE UNA SECCION CON ENVUELTA, O SECCIONES DEL REACTOR, DENTRO DEL CUAL SE INYECTA UN FLUIDO REFRIGERANTE, O REFRIGERANTE, Y SE VAPORIZA PARA EXTRAER EL CALOR DE LA REACCION. EL FLUIDO REFRIGERANTE, O REFRIGERANTE, EN RELACION TERMOPERMUTADORA CON LOS TUBOS, EXTRAE LOS CALORES EXOTERMICOS DE LA REACCION DE LA MEZCLA DE POLIMERIZACION, Y MANTIENE LA MEZCLA DE POLIMERIZACION A UNA TEMPERATURA UNIFORMEMENTE BAJA. SE DISPONE UNA CIRCULACION UNIFORME DE FLUJO DEL LODO, QUE CONTRIBUYE AL MANTENIMIENTO UNIFORME DE TEMPERATURA BAJA, MEDIANTE EL USO DE (3) UN DIFUSOR (60) Y (4) SISTEMA (40) DE BOMBEO DE FLUJO MEZCLADO, CON SU IMPULSOR (43), EN VIRTUD DEL CUAL SE DESARROLLA UN CABEZAL DE PRESION ADECUADA DE PERFIL DE PRESION UNIFORME, A TRAVES DE LOS LADOS DE ENTRADA DE LOS TUBOS CENTRALES (20) PARA MANTENER LA DISTRIBUCION DE FLUJO UNIFORME DENTRO DEL SISTEMA DE PASO DE DOS TUBOS, A RITMO ELEVADO DE CIRCULACION. NO HAY ROTACION VORTICIAL EN LA SALIDA DEL CONJUNTO IMPULSOR-DIFUSOR, Y NO HAY BURBUJAS DE CAVITACION COMUNMENTE ASOCIADAS CON SISTEMAS DE PASO DE UN TUBO, QUE EMPLEAN UN TUBO DE ASPIRACION CENTRAL Y BOMBEO AXIAL DE FLUJO. SE OBTIENEN MEZCLAS PERFECCIONADAS, EFICACIA HIDRAULICA ELEVADA Y RITMOS DE PRODUCCION SUPERIORES, CON FONDOS SUCIOS DE POLIMERO BAJO.
