Abstract
PROCEDIMIENTO PARA EL TRATAMIENTO DE UNA CORRIENTE GASEOSA QUE CONTIENE OXIDOS DE NITROGENO, EN PARTICULAR PARA LA SEPARACION DE LOS OXIDOS DE NITROGENO DE LA CORRIENTE GASEOSA QUE LOS CONTIENE.COMPRENDE LAS SIGUIENTES OPERACIONES: PRIMERA, SE PREPARA UN DISPOSITIVO DE CONTACTO GAS-LIQUIDO EN CONTRACORRIENTE; SEGUNDA, PARA VALORES DE LA RELACION NO/NO2 SUPERIORES A LA UNIDAD, SE AUMENTA LA RELACION K DEL VOLUMEN DE RETENCION LIQUIDO, EN M, AL CAUDAL DE LA CORRIENTE GASEOSA, EN METROS CUBICOS NORMALES/HORA, AL OBJETO DE QUE LOS OXIDOS DE NITROGENO SEAN ABSORBIDOS; Y POR ULTIMO, SE PROVOCA A CONTINUACION UNA OXIDACION DEL MEDIO AL OBJETO DE DISMINUIR LOS VALORES DE LA RELACION NO/NO2 Y VOLVER A SITUARSE EN LAS CONDICIONES DE PARTIDA.
