Abstract

EN EL PROCESO DE SINTESIS DE AMONIACO, LA PIEZA DEL CONVERTIDOR IMPULSADO POR GAS CALIENTE SE REFRIGERA A TRAVES DE UN GAS FRIO. PARA SOLUCIONAR ESTE PROBLEMA Y PODER POSIBILITAR CONSTRUCCIONES DE PAREDES DELGADAS PARA EL CONVERTIDOR Y PODER TRABAJAR CON SUSTANCIAS ACTIVAS ECONOMICAS, EL GAS DE PROCESO MULTIPLE SE CONDUCE POR EL CONVERTIDOR DE AMONIACO. EL AMONIACO SE SEPARA POR EL EXTREMO DE UN TRAYECTO DE ENFRIAMIENTO COMO CONDENSADO. EL AIRE FRESCO COMO GAS REFRIGERANTE LIGRA DE AGITACION SE CONDUCE A LA ZONA DE GAS CALIENTE DE PROCESO. EL DISPOSITIVO SE CARACTERIZA POR UN CONVERTIDOR, UN CAMBIADOR DE CALOR Y UN SEGUNDO CONVERTIDOR (3) PARALELO AL PRIMER CONVERTIDOR (2) CON UN GENERADOR DE VAPOR (4) COMO CAMBIADOR DE CALOR SITUADO ENTRE AMBOS CONVERTIDORES (2,3) Y EN LA PARTE BAJA. UNA ALIMENTACION DE GAS REFRIGERANTE SE REALIZA DELANTE DE LA CAMARA DE LOS CAMBIADORES DE CALOR. ASI COMO UN AFIANZADOR DE DOBLE TUBO DEL PRIMER CONVERTIDOR QUE LLEVA UNOS TUBOS DE GAS CALIENTE AL SEGUNDO CONVERTIDOR (2).
