Abstract

DONDE EL METODO COMPRENDE: a) PASAR UNA MUESTRA DEL MEDIO DE DICHO PROCESO EN UN BUCLE LATERAL Y AISLAR LA MUESTRA DEL MEDIO DE PROCESO REMANENTE EN EL REACTOR; b) CIRCULAR LA MUESTRA EN EL BUCLE Y TEMPERARLA ALLI A UNA TEMPERATURA DESEADA; c) REALIZAR UNA MEDICION DE POR LO MENOS UN SOLO PARAMETRO DE PROCESO DE LA MUESTRA A LA TEMPERATURA DESEADA; Y, d) CIRCULAR DE MANERA AISLADA UNA FRACCION DE MUESTRA OBTENIDA DEL SUB-BUCLE DEL BUCLE LATERAL, MIENTRAS EL REMANENTE SE MANTIENE INACTIVO, POR LO CUAL NO SE REALIZA TEMPLADO EN EL SUB-BUBLE MIDIENDOSE UNO O MAS PARAMETROS EN LA MUESTRA DEL SUB-BUCLE. EL TEMPERADO SE LOGRA OPERANDO UN INTERCAMBIADOR DE CALOR EN EL BUCLE. LA TEMPERATURA DEL REACTOR DE DICHO SUBBUCLE SE MIDE OPCIONALMENTE. EL SISTEMA INCLUYE: UNA SALIDA Y UNA ENTRADA; EL BUCLE LATERAL CONECTADO AL REACTOR VIA LA SALIDA Y ENTRADA Y CONTIENE UN SUB-BUCLE, INCLUIDO EN UNA CAJA DE MEDICION, QUE NO TIENE MEDIOS PARA EL TEMPLADO Y ES OPERADO AISLANDOLO DEL BUCLE; MEDIOS PARA LA CIRCULACION DE LA MUESTRA; VALVULAS PARA AISLAR LA MUESTRA EN EL BUCLE DEL MEDIO DE PROCESO REMANENTE EN EL REACTOR; MEDIOS PARA TEMPLADO DE LA MUESTRA; MEDIOS PARA MEDIR POR LO MENOS DICHOS PARAMETROS, TAL COMO SENSORES; Y, MEDIOS DE TAMIZADO QUE COMPRENDE UNA CARCASA CON ENTRADA Y SALIDA, UNA ESTRUCTURA DE MALLA Y UN MARCO DENTRO DE LA CARCASA QUE SOPORTA EL TAMIZ. LA CARCASA CUENTA CON DOS CUMBRERAS EN SUS PAREDES VERTICALES. EL SISTEMA SE EMPLEA PARA LA PRODUCCION CONTROLADA DE RESINASWHERE THE METHOD INCLUDES: a) PASSING A SAMPLE OF THE MEDIA OF SAID PROCESS IN A SIDE LOOP AND ISOLATING THE SAMPLE OF THE REMAINING PROCESS MEDIA IN THE REACTOR; b) CIRCULATE THE SAMPLE IN THE LOOP AND TEMPER IT THERE TO A DESIRED TEMPERATURE; c) MAKE A MEASUREMENT OF AT LEAST ONE SINGLE PROCESS PARAMETER OF THE SAMPLE AT THE DESIRED TEMPERATURE; AND, d) CIRCULATE IN AN ISOLATED WAY A SAMPLE FRACTION OBTAINED FROM THE SUB-LOOP OF THE SIDE LOOP, WHILE THE REMNANT REMAINS INACTIVE, THEREFORE IT IS NOT PERFORMED TEMPERED IN THE SUB-BUBLE BY MEASURING ONE OR MORE PARAMETERS IN THE SUB SAMPLE -LOOP. TEMPERATURE IS ACHIEVED BY OPERATING A HEAT EXCHANGER IN THE LOOP. THE TEMPERATURE OF THE REACTOR OF SUCH SUB-LOOP IS OPTIONALLY MEASURED. THE SYSTEM INCLUDES: ONE EXIT AND ONE ENTRY; THE SIDE LOOP CONNECTED TO THE REACTOR VIA THE OUTLET AND INLET AND CONTAINS A SUB-LOOP, INCLUDED IN A MEASURING BOX, WHICH DOES NOT HAVE MEANS FOR TEMPERING AND IS OPERATED BY ISOLATING IT FROM THE LOOP; MEANS FOR THE CIRCULATION OF THE SAMPLE; VALVES TO ISOLATE THE SAMPLE IN THE LOOP FROM THE REMAINING PROCESS MEDIA IN THE REACTOR; MEANS FOR TEMPERING THE SAMPLE; MEANS FOR MEASURING AT LEAST SUCH PARAMETERS, SUCH AS SENSORS; AND, SCREENING MEANS INCLUDING A HOUSING WITH INLET AND OUTLET, A MESH STRUCTURE AND A FRAME INSIDE THE HOUSING THAT SUPPORTS THE SCREEN. THE HOUSING HAS TWO RIDGES ON ITS VERTICAL WALLS. THE SYSTEM IS USED FOR THE CONTROLLED PRODUCTION OF RESINS
