Abstract

DISPOSITIVO PARA QUITAR EL NITROGENO DE GASES DE SALIDA DE CENTRALES ELECTRICAS(GAS BRUTO) PROCEDENTES DE UNA INSTALACION DE DESULFURACION POR GASES DE HUMO QUE ANTES DE INYECTAR AMONIACO SE CALIENTAN POR INTERCAMBIO DE CALOR CON LOS GASES DESNITROGENADOS (GAS PURO) Y METIENDO CALOR ADICIONAL A LA TEMPERATURA DE CATALIZADOR NECESARIA. INSTALACIONES DE DESNITROGENACION CONOCIDAS, EQUIPADAS CON INTERCAMBIADORES DE CALOR DE REGENERACION TRABAJAN CON GRANDES PERDIDAS DE RANURA Y DE FUGA LO QUE LIMITA EL GRADE DE DESNITROGENACION ALCANZABLE Y POR LO TANTO EL GRADO DE EFECTIVIDAD. ADEMAS PARA LAS INSTALACION ES CONOCIDAS DE DESNITROGENACION OCUPAN MUCHO DESPACIO LO QUE REQUIERE GRANDES MEDIDAS DE AISLAMIENTO CALORICO A CAUSA DE LAS GRANDES SUPERFICIES LIBRES PARA QUE NO EMPEORA EL GRADO DE EFECTIVIDAD POR PERDIDA DE CALOR. SE PROPONE QUE SE UTILICE PARA EL INTERCAMBIO DE CALOR ENTRE EL GAS BRUTO Y EL GAS PURO UN INTERCAMBIADOR DE CALOR DE PLACAS (4) QUE TRABAJA CON CONTRACORRIENTE CRUZADA, EN CUYO CANAL DE SALIDA (9) SE ALIMENTA CON EL CALOR ADICIONAL Y DONDE REALIZA LA INYECCION DE AMONIACO (14) EL FINAL DE CANAL DE SALIDA (9) SE ENCUENTRA UNA TAPA DE REENVIO (16) Y ENTRE SU SALIDA Y LA NUEVA ENTRADA DE LOS GASES DESNITROGENADOS EN EL INTERCAMBIADOR DE CALOR DE PLACAS (4) SE ENCUENTRAN LOS CATALIZADORES (9A, 9B).
