Abstract
LA PRESENTE INVENCION SE REFIERE A UN METODO PARA REDUCIR EL CONTENIDO DE OXIDO DE NITROGENO, ESPECIALMENTE DIOXIDO DE NITROGENO DE LOS GASES EFLUENTES PROCEDENTES DE UNA COLUMNA DE ABSORCION PARA LA FABRICACION DE ACIDO NITRICO Y UN APARATO PARA LA REALIZACION DEL METODO. LA ABSORCION EN LAS ETAPAS 1-8 SUPERIORES, PREFERIBLEMENTE EN LAS ETAPAS 2-4 SUPERIORES DE LA COLUMNA, SE REALIZA PARA UNA RELACION ENTRE EL AREA DE CONTACTO EN EL NIVEL DE LIQUIDO PARA ABSORCION EN LOS PLATOS Y EL ESPACIO LIBRE DE GAS PARA LA OXIDACION DE 1,5-5, PREFERIBLEMNETE DE 2-3, MAYOR QUE LA CORRESPONDIENTE RELACION PARA LOS PLATOS HORIZONTALES INDICADA MAS ABAJO. SE AJUSTA LA RELACION ENTRE EL AREA DE CONTACTO Y EL ESPACIO LIBRE DE GAS AUMENTANDO LA ALTURA DE REBOSE PARA EL VOLUMEN DE LIQUIDO EN LOS PLATOS SUPERIORES. DICHA RELACION PUEDE AJUSTARSE TAMBIEN, REDUCIENDO LA DISTANCIA ENTRE LOS PLATOS SUPERIORES. EL APARATO COMPRENDE UNA COLUMNA DE ABSORCION (1) QUE TIENE PLATOS HORIZONTALES (6) CON UN NIVEL DE LIQUIDO (A,B) Y ESPACIOS DE OXIDACION (9) ENTRE LOS PLATOS (6). LA ALTURA DE REBOSE EN LOS PLATOS 1-8 SUPERIORES (6) DE LA COLUMNA PUEDE REGULARSE DE MANERA QUE PROPORCIONE UN NIVEL DE LIQUIDO (A9 DE 1,5 A 5 VECES EL NIVEL DE LIQUIDO (B) DE LOS PLATOS (6) SITUADO MAS ABAJO DE LA COLUMNA, PREFERIBLEMENTE (A) = (2-3).(B). LA PARTE SEMIESFERICA (2) DE LA COLUMNA (1) ESTA SEPARADA DEL VOLUMEN DE OXIDACION SUPERIOR (9) POR UNA PLACA (4) NO PERFORADA. LOS DOS VOLUMENES (2,9) ESTAN EN COMUNICACION MEDIANTE LAS ABERTURAS (10) ENTRE LOS PLATOS O EN LOS PLATOS (4). UN TUBO (3) QUE PASA POR LA PARTE SEMIESFERICA (2) PUEDE TRANSPORTAR LOS GASES EFLUENTES FUERA DE LA COLUMNA (1).
