Abstract
PROCEDIMIENTO E INSTALACION DE RECUPERACION DE OXIDOS DE NITROGENO DE UNA MEZCLA GASEOSA. EL PROCEDIMIENTO CONSISTE EN HACER PASAR SIMULTANEAMENTE LA MEZCLA GASEOSA Y UN LIQUIDO ACUOSO, TAL COMO AGUA PURA O UNA SOLUCION NITRICA, SOBRE UN LECHO DE ABSORBENTE CARBONADO, TAL COMO CARBON ACTIVO. EL PASO DE GAS Y LIQUIDO SE PUEDE EFECTUAR EN CORRIENTES DEL MISMO SENTIDO, EN CONTRACORRIENTE O EN CORRIENTE CRUZADAS. LA PRESION OSCILA ENTRE 0,9 Y 12 BARES ABSOLUTOS, Y LA TEMPERATURA ESTA COMPRENDIDA ENTRE 2 Y 80 C. LA INSTALACION CONSTA DE LOS SIGUIENTES ELEMENTOS: 1) UNA COLUMNA CON ENTRADA DE LIQUIDO EN LA PARTE ALTA, ASI COMO CON SALIDA DE GASES PARA SU DEPURACION. 2) UN RECIPIENTE DE RECUPERACON DE LIQUIDO EN LA PARTE INFERIOR. 3) UNA BOMBA CON ENTRADA DE LIQUIDO DE RIEGO Y DE LIQUIDO DE RECIRCULACION Y SALIDA DE COLUMNA. 4) UN DISPOSITIVO RECUPERADOR. 5) VALVULAS DE CONTROL.
