Abstract
UN PROCESO DE AMONIACO/UREA INTEGRADO Y UNA FABRICA PARA LLEVAR A CABO EL MISMO. EL PROCESO COMPRENDE RECICLAR UNA CORRIENTE DE PURGA A ALTA PRESION COMPUESTA PRINCIPALMENTE DE AIRE DESDE EL CICLO DE SINTESIS DE UREA HASTA EL REFORMADOR AUTOTERMICO EN UNA UNIDAD DE PRODUCCION SINGAS DEL PROCESO DE AMONIACO. DE TAL MANERA QUE UNA ENERGIA DE COMPRESION NECESARIA PARA LA SINTESIS DE AMONIACO PUEDE SER REDUCIDA YA QUE UNA PARTE DE LA ALIMENTACION DE AIRE A ALTA PRESION AL REACTOR AUTOTERMICO ES SUMINISTRADA POR LA RECIRCULACION DE LA CORRIENTE DE PURGA DE UREA. ADEMAS, EL EQUIPO QUE SE NECESITA PARA LIMPIAR COMPLETAMENTE LA CORRIENTE DE PURGA DE UREA ES ELIMINADO CONSIDERABLEMENTE.
