Abstract

CON UN DISPOSITIVO PARA LA REGULARIZACION ESPECIALMENTE DE UN CONVERTIDOR DE AMONIACO CON UNA ENTRADA/SALIDA DEL GAS DEL PROCESO, AL MENOS CON UN CAMBIADOR TERMICO Y AL MENOS CON UN LECHO DEL CATALIZADOR ASI COMO CON UNA ALIMENTACION DEL GAS Y CON UN TUBO CENTRICO, ASI COMO CON UNA ALIMENTACION DEL GAS DE PROCESO PARA EL CAMBIADOR TERMICO O SEA PARA EL LECHO DEL CATALIZADOR, DONDE EL CAMBIADOR TERMICA, Y ALREDEDOR DE ESTE EL PRIMER LECHO DEL CATALIZADOR ESTA DISPUESTO SIMETRICO/ROTATIVAMENTE AL TUBO CENTRICO, HAY QUE BUSCAR UNA SOLUCION, CON QUE EL SOBRANTE DEL GAS REGULADO, GAS DE MEDIA DRACMA Y UNA PARTE DEL GAS DE PROCESO ES CONDUCTIBLE CON OTRAS TEMPERATURAS Y/O CONDICIONES OBVENCIONALES A CADA POSICION DE UN REACTOR EN LA CORRIENTE DEL GAS, HABITUAL, DONDE LA DISOLUCION TIENE QUE ENCONTRARSE DE TAL MANERA, QUE LA MEZCLA ADICIONAL O SEA EL CONDUCTOR BYPASS ES COMPLETAMENTE CERRABLE, Y PARCIALMENTE IMPULSABLE O SEA SE PUEDE ABRIR COMPLETAMENTE. ESTO SE CONSIGUE DE TAL MANERA, QUE ELTUBO CENTRICO (14) PARA LA REGULACION DE LA TEMPERATURA COMO TUBO DE ALIMENTACION DEL GAS REGULADO LLEVA COMPLETAMENTE EL CAMBIADOR TERMICO (4 O SEA, 5, O SEA, 6) Y ESTA EQUIPADO EN SUS FINALES CON SALIDAS REGULABLES (18) PARA LA MEZCLA ADICIONAL, PARCIAL DEL GAS REGULADO EN EL PROCESO DE LA CORRIENTE DEL GAS, ANTE CUYA CIRCULACION DEL LECHO DEL CATALIZADOR (4) O SEA PARA LA MEZCLA ADICIONAL DE LA CORRIENTE DEL GAS REGULADO EN LA CORRIENTE DEL GAS DEL PROCESO SEGUN SU CIRCULACION DEL LECHO DEL CATALIZADOR (4) Y DEL CAMBIADOR TERMICO (7).
